What Exactly Is Fish Habitat and Why Must We Care?Thomas E. Bigford Office of Habitat Conservation, NOAA/National Marine Fisheries Service, Silver Spring, MD 20910. E-mail: Thomas.bigford@noaa.gov
“Fish habitat” is a simple term. We can easily imagine a fish languishing under a log or in a kelp forest, and we can picture a school of forage fish zipping through the water column. We can also grasp that the preferred space for many species might change as the seasons change and the years pass by. But the rest of the story is not quite so simple, mostly because life is more complicated and knowledge is often limited. This month’s “Fish Habitat Connections” seeks to demystify those details so we can appreciate the intricacies in the fish habitat world and become more emboldened to serve fish not just as a meal but as they deserve. Let’s begin with semantics. Each fish occupies its preferred niche in the ecosystem. The environmental conditions of that space define the fish’s preference at each life stage—water temperature, depth, salinity, flow, bottom type, prey availability annual cycles, and much more. It is important for us as professionals to place those variables in proper context so that individual fish can survive, fish stocks can flourish, fishery management can succeed, and society can benefit from our nation’s waters. That simplistic summary reflects our hopes, which are complicated by the reality that we know very little about our most basic habitat questions. With luck, we know where fish live throughout their life cycles. But oft times we have few insights into the shifting preferences of each life stage. Even that knowledge is elusive unless we have close observations from multidecadal stock assessments or the insights offered by a healthy fishery. Almost universally, we rarely understand the relationships between fish and their habitat.
If a wetland is dredged, how will the local fish populations change over the short and long term? If a dam is breached, will the new hydrological regime support native species or invite invasive species? If an acre is protected or restored, how will the population respond? Will harvests increase? These issues read like the final program at many an American Fisheries Society (AFS) conference. They have vexed us as a profession for decades. We must manage fisheries with the best available information, scant as it might be. And we must identify our primary needs so that gaps are addressed. COLUMN Fish Habitat Connections There is also the still-new concept of ecosystem-based approaches. Habitat must be an essential variable in stock assessments, but those analyses must be conducted with an ecosystem in mind. Those perspectives can be as important as data. Without that challenge, we won’t even know we have a data gap. Considering how complex this simple topic can be, and how it reflects human pressures from our coasts to the mountains, it is probably no surprise that we continue to lose habitat function at alarming rates. Along our oceans, marine and estuarine wetland loss was three times higher between 2004 and 2009 than in the previous 5 years (Stedman and Dahl 2008; Dahl 2011). Inland wetland loss is not as severe, but hundreds of rivers representing thousands of river miles are compromised by blockages that prevent fish movement upstream or downstream. The first-ever national fish habitat assessment found that 53% of our estuaries are at high or very high risk of habitat degradation (National Fish Habitat Board 2010). Given those numbers, it is unfortunate that those places provide vital nursery habitats for many of our favorite fish. As fishery professionals from all disciplines, our assignment is to combine our skills to protect important habitats and restore those that are degraded. Our mission will be slightly less daunting if we and our partners can set a pace to match the steady pressure of human population growth and looming challenges such as climate change. AFS represents an incredible knowledge base. If anyone can analyze our habitat knowledge, fill our priority gaps, apply lessons learned, and improve habitats for the benefit of all, it is us.
More habitat articles at fishiding.com Next month we will shift from the nuances of semantics to the harsh realities of the challenge before us. It is imperative that we engage now! Economic and ecological facts urge AFS, its units, each of us, and our home institutions to accept the challenge. We will explain the opportunities before us and how our collective skills are needed for success. REFERENCES Dahl, T.E. 2011.

Fisheries in West Virginia and New Mexico are showcasing a new generation of manmade habitat, thanks to innovative state conservation directors in the B.A.S.S. Nation (BN).
Both Jerod Harman and Earl Conway saw the need for effective and long-lasting habitat in reservoirs that endure huge water fluctuations on a regular basis. More habitat articles at fishiding.com
“Climate change is already impacting the Southwest,” said New Mexico’s Conway. “Over-allocation of water rights and drought have drained many reservoirs in New Mexico and west Texas. Shoreline and aquatic vegetation is gone and replanting is futile when lake levels fluctuate 20 feet or so every year.
“That’s where floating islands come to the rescue.”
In West Virginia, meanwhile, the West Virginia BN has teamed with a company that makes fish habitat from recycled vinyl and reclaimed PVC to build an “oasis for bass” in Sutton Lake, according to Jerod Harman.
It consists of pea gravel, spider blocks, artificial structures fromFishiding, and vegetation growing in a 5,000-square-foot cage on a mud flat, with a creek channel nearby.
“The artificial structures attract the bass looking for a place to spawn,” Harman explained. “The pea gravel provides the correct bottom structure for bedding.
“When the young bass hatch, the artificial structures help provide a protective environment. The periphyton (mixture of algae, microbes, and bacteria that forms the base of food chain) will provide nutrients for growth, and, later on, the small bass fry can relocate to inside of the vegetation cage for protection from predators.
“This is something that I am really excited about!”
Harman added that he believes the habitat made by Dave Ewald’s Illinois company, which features vinyl strips attached to a heavy base, will greatly enhance periphyton growth, as well as provide better cover for survival of young bass than will the spider blocks alone.
“The structures are ready for installation right out of the box, and David was great to work with,” the conservation director said. “I would definitely recommend these, especially for a small group of volunteers who need to complete a larger-scale project in a limited amount of time.”
Conway and the New Mexico BN also are growing periphyton, but on floating islands instead of vinyl strips. One of those islands, complete with spawning platform, won the 2010 Berkley Conservation Award and was the first step in what the conservation director hopes will be a major habitat restoration project for Elephant Butte.
Bruce Kania’sFloating Island International, a Montana company, has provided the New Mexico BN with prototypes and expertise.
“Floating islands aren’t new,” Conway said. “They occur in nature and have a proven track record for improving water quality and enhancing fish production, but I think that we are just beginning to realize how they can add an entirely new dimension to habitat restoration options.
“My experience is that the shade and food they provide makes them better fish attractors than boat docks or tire water breaks. They are being used more often in public waters and it is just a matter of time until someone wins a major tournament or catches a monster bass off a floating island.”
Machado Lake and its surrounding environment are in need of a major recovery effort. The Los Angeles Regional Water Quality Control Board has identified the lake as an impaired water body for DDT, PCBs, pesticides, ammonia, algae, eutrophic conditions, trash, and odor, all of which have negatively affected human as well as aquatic health. This restoration project needs the support of the community to meet the goals of clean water, wildlife improvements, and healthy parks for Los Angeles.
Engineers for the project CDM Smith, specifiy artificial products from Fishiding.com for numerous reasons. The inert, reclaimed PVC limbs will last for decades or more underwater. The PVC material attracts bio-film and peripyton growth excessively, superior to other products. The ability to bend to shape and drop in the water landing upright, is another key feature.
American made from post consumer materials with no manufacturing process, these multi-faceted and species specific habitat units excell in developing protection and food, in the purest and natural form. Leading the Nation and the World in cutting edge design and engineering experience, CDM Smith is the firm, policy makers look to for advice and decisions utilizing BMP’s for our Nation and beyond.
Non native turtles such as red eared sliders as well as snapping turtles have been found, all dumped by people. Essentially, Lake Machado has turned into a repository for unwanted non native aquatic pets. Which is a shame considering the fact long ago , the lake was a natural body of water supporting indigenous species that no longer reside there.
Not everything about the lake is unpleasant. Amazingly, it attracts a wide variety of wading and aquatic bird species: snowy egrets, blue herons, green herons, black crowned night herons, cormorants, coots, ducks, bitterns, Caspian terns and least terns.
Driving by Harbor City’s 231-acre regional park, Machado Lake looks to be a serene and picturesque oasis. Close up, the reality is harsh.
For years the lake, which holds runoff storm water from the area, has collected everything from pesticides to swarms of mosquitoes and piles of trash.
What once was a pristine spot for bird watchers has deteriorated through the decades. The park now draws homeless encampments and has become a haven for lewd activity.
Habitat products both natural and artificial, are designed throughout the lake, creating a perfect environment for aqautic development and health. Hundreds of Fishiding Keeper and Safehouse models will be installed in clusters of five. These models allow engineers to place the habitat structures on ranging degrees of slopes, overseeing detailed specifications regarding spacing, type and texture.
The plan looks like a well designed landscape, only to be submerged for the fish. Large tree trunks, boulders and native plants will also be installed in abundance. Spawning gravels and aggregates will be spread in key areas to promote a yearly, healthy spawn of native fish and aquatic life.
Laddie Flock, owner of Floating Islands West, will be a key player in the installation and maintainence of the Floating Islands.
Floating islands will be created for nesting areas to support native habitat, as well as providing support for additional habitat products to be suspended from the islands, which act as floating treatment wetlands. These magical islands not only provide habitat for fish, birds, bugs etc. , but even more amazing, they remove unwanted, over abundant nutrients and convert them back to food for the fish, naturally without chemicals. Fishing will be fantastic and the water quality will impress anyone and all that enjoy it’s surroundings.
Benches and other park amenities also will be added to the 231-acre Ken Malloy Harbor Regional Park that surrounds the body of water.
“There are four goals: water quality improvements, recreational enhancements, wildlife habitat improvements and flood control,” said Michelle Vargas, public information officer for the city of Los Angeles.
“Clearly this will be a major improvement over what we’ve seen in decades of neglect,” said Jess Morton, also of the Audubon Society.
“You won’t see the summertime die-off of fish and birds caused by nutrient loads,” Morton said.
Algae, pesticides and pollutants such as metals from area industry are likely to be found in the sediment at the bottom of the lake once dredging begins and safely removed.
Once known by locals as “the slough,” the area was owned by the Dominguez family in the 1700s and American Indians remained prevalent around the lake. The property later went to the Sepulveda family.
It was annexed in 1906 to the city of Los Angeles and eventually was designated as a regional park.
In the 1990s, the park was named for Ken Malloy, a San Pedro environmentalist who died in 1991 at the age of 78.
Malloy came upon the undeveloped area in the 1930s when his car bumped into some cows grazing on the property and spent years nurturing it.
Convinced it could someday become a grand regional park, Malloy later formed the 62-acre Machado Youth Campground within the park. He was instrumental in planting hundreds of trees in the park as well, working with the California Conservation Corps.

Official Tournament Rules:The following rules are designed to promote sportsmanship among the anglers and to provide a fair competition. Failure to comply with any rules may result in a weight penalty or disqualification from any tournament.
1. Inclement Weather Plan – In the event of unfavorable weather on the day of the event, the event will continue as scheduled during rain only. In the event of lightning or thunder, all boats will be secured and participants asked to return to the nearest, safest location. It is the responsibility of the Tournament Coordinator to determine whether or not the event should be called or wait until the weather clears. If the event is called, the winning weights will be determined by the fish that were caught up until that point in the day. Cancelling the event may occur if unforeseen dangerous natural events, low water levels, or unexpected problems occur that may impede the tournament.
2. All participants must be back at the boat landing no later than 3:00 pm. There will be a one pound deduction every minute a participants is late getting back to the landing up to 15 minutes. After 15 minutes, no weight will be allowed for that boat’s participants. Boat captains are responsible for making sure the boat is back to the dock by 3:00 pm and at the weigh-in no later than 3:00 PM EST. Boat captains are responsible for notifying the Tournament Coordinator in advance of the 3:00 pm closing time of any problems that may have occurred. 3. Each boat must have a bump board or way to measure the length of the fish. No fish fewer than 12 inches may be kept. Fish brought to the scales at weigh-in less than the 12 inches will not count toward the cumulative weight for a middle or high school club. There will be a five (5) fish black bass limit per individual. Black bass includes largemouth, smallmouth, spotted and/or redeye bass. Fish may be culled if an individual has 5 fish in the live well. No more than 5 fish can be in the live well at any one time individual. All fish must be kept alive. Penalty will be 1/2 pound per each dead fish. If an individual is caught with more than the 5 fish limit in their livewell by tournament officials, the fish will be culled starting with the largest fish until they are down to the stated limit of 5 fish. 4. Ties will be broken, if the poundage is equal, in the following manner: First criteria will be the largest fish; second criteria will be the number of fish. Any fish found to be altered or in poor condition (mashed, mangled or mauled) will not be counted at the discretion of tournament officials. 5. All student anglers and boat captains must wear a US Coast Guard approved Personal Floatation Device (PFD) while boat motor is engaged. Anglers will be disqualified if found to have removed their PFD. 6. Participants must only use the gear that is in the boat when the boat leaves the dock at the start of the day. Permitted methods of fishing will be the use of artificial lures only, no live bait of any sort. Each angler aboard shall have no more than 3 rods. Only one fishing rod may be in use at any one time by an angler. Bass may be landed by use of conventional hook and line. No snagging of fish allowed. In addition to tournament limits, all SC freshwater fishing laws must be adhered to. 7. Nets are allowed. 8. Every boat must have an adult captain, age 21 years old or older, for driving purposes and only that captain can drive when the outboard motor is in use. Student anglers may operate the trolling motor when the outboard motor is not in use. 9. No live bait or trolling is allowed. 10. Boats provided by volunteers must be a minimum of 16 feet in length, have front and rear casting decks, a front mounted trolling motor, an aerated live well capable of keeping alive the [two-man team’s or individual’s] five bass limit. Boats must also have console steering (no tiller), an ignition safety kill switch, and all safety equipment as required by the United States Coast Guard. Boats participating in this tournament must have current boat registration. All boats must be subject to a safety check prior to the blast off. 11. Anytime the gasoline engine is in use, boat captains must be seated in the driver’s seat and anglers should be seated in the appropriate locations aboard the vessel. 12. Boat captains must operate boats in a safe manner abiding all boating laws when carrying student anglers to fishing locations. Student anglers make the decisions on what areas to fish on the lake and what direction to go. Boat captains cannot make suggestions on areas to fish. 13. Boats shall not exceed the maximum horsepower capacity on the boat’s maximum horsepower rating affixed to the boat by the manufacturer or a maximum of 250 hp. The maximum capacity rating must be legible. 14. Use of cell phones by student anglers is prohibited during the tournament. Captains may use cell phones to communicate emergencies only. All boats are required to have a cell phone and must provide the Tournament Coordinator the number of that cell phone in case of an emergency or to notify of bad weather conditions. Any use of a cell phone or any other communication devices to exchange fishing information is prohibited and will result in immediate disqualification. In the event of an emergency, all boat captains should call 911 first and then notify tournament officials. 15. All participants 16 years of age and older must have a valid South Carolina or Georgia Recreational Freshwater Fishing License. 16. Anglers may assist one another in netting fish. Coaches may also assist in netting fish, but are not allowed to assist tying lures or handling fish or gear. 17. After the weigh-in, all fish must be released immediately. All fish that are put in the live well must be kept alive. Dead fish will have a 1/2 pound deduction and cannot count as the large fish for that angler. 18. Dead fish may not be culled. 19. Each school is responsible for bringing 1 boat per 2 anglers. Only two students in each boat. [The total weight of the 5 fish limited to that boat will count for the total weight of the 5 fish limited to each angler will count for the cumulative weight.] 20. The total weights for each of the 5 fish limited to an individual will count towards the overall team total for the tournament. Individual weights will be recorded for the top fish designated by each boat. The largest fish award and most weight boat captain award will be given at the tournament. 21. Participants must stay completely in the boat unless they are using an authorized restroom facility or due to some other emergency or malfunction. If an emergency or malfunction occurs, the boat must contact the Tournament Coordinator prior to leaving the boat. In the event of a needed restroom break, the boat captain needs to contact tournament officials. Student anglers may leave and return to the boat at the official checkpoint designated by tournament officials. 22. Any transfer of fish from one live well to a different live well in another boat due to malfunction must be made in the presence of the Tournament Coordinator or other adults as approved by tournament officials. 23. On the day of the tournament, teams will be limited to putting into the water the number of boats based on the number of participating anglers. No additional boats, contacting coaches or other competitors from a team can be put into the water unless approved by tournament officials. Contestants may not obtain fishing patterns or locations from non competitors, follow a non-competitor’s boat or participate in the practice of “hole-sitting,” a practice wherein a non-competitor sits on a fishing spot, holding it for a contestant. In addition, non-competitors may not place markers for contestants. All of these acts are prohibited and will result in the immediate disqualification of the boat. 24. Only the designated boat captain and the two anglers assigned to that boat may be aboard the boat during competition. 25. At the time of check-in, all student anglers and their boats must comply with all the rules applied by tournament officials. At check-in, boat captains shall report their tournament boat identification number and anglers must present their limit and report any dead fish. Once the individual’s catch has been verified, anglers will proceed to the weigh-in. Boat captains must check in even if they don’t have any fish.

Growing big fish starts with growing lots of food to feed them. In order for the fry and forage fish to thrive and reproduce, they need mass amounts of food to develop and prosper.
Minnows, small panfish and fry feed on film that grows on surfaces underwater called peripyhton. This magical micro-floral community of bacteria and fungi, protozoa and zoo-plankton, dance together forming this wonderful highly efficient, nutrient converting fish food.
Phosphorus and nitrogen are often the biggest culprits in abundant weed growth and eutrophic waters. Converting these nutrients into fish food and ultimately fish, is not new and has been being used with ongoing success sometimes called brush parks. Create the food source and the fish will come.
The more surface area available, the more food can grow. Weed beds are a good example of surfaces for this film to grow and hiding places for the small fish.
The Hangout is where the smaller fish will congregate and eat this highest form of food available, within the protection of the maze of vinyl limbs that surround the feeder bag.
The plastic mesh feeder bag holds an incredible 400 square feet of surface area from a matrix of woven plastic recycled from drinking bottles. Weighing just over two pounds and approximately ten inches diameter and two feet long, these bags hold the key to fish development.
Over thirty two square feet of flexible vinyl limbs, the same material in all fishiding fish habitat products, complete this protective eating establishment. Dozens of unique habitat models at fishiding.com
Bend limbs and pinch crease with fingers, no tools or additional supplies needed.
Opens to a full 46″wide by 48″ tall, hang at any depth, unit sinks.
Each unit comes with 5.5 pounds of pre-drilled vinyl limbs, ranging in length from 12″-28″ long and 1″-4″ wide with feeder bag with ten feet of mono bait-ball line.
Hang unit from underside of dock or pier for year around fishing action.
Suspend unit from raft or tree limb to keep predators close by your food source.
Attach unit to full size habitat unit or anchor and add foam to feeder bag to add buoyancy.
Tie multiple units together for deep water applications.
David Beasley, head Fisheries Biologist for Solitude Lake Management talks about the need for fish habitat for a balanced aquatic environment. Fishiding.com and Solitude Lake Management have been working closely together to help clients up and down the East coast improve water quality and fish habitat. Beasley has been a strong leader in helping lake and pond owners understand the multiple benefits of adding and improving fish habitat in their waters.

Together, working with numerous Federal and State agencies , private lake owners, lake management associations and DNR Biologists, habitat restoration and improvement is near the top of everyone’s list.
Artificial fish habitat made from PVC, never decay and only improve with time. Un-like wood, plants and natural products that decay over time and remove dissolved oxygen from the water, bio film and periphyton growth adhere to PVC, creating nature’s finest available food for fry development. This magical film excels in nutrient uptake, converting over abundant phosphorus, nitrogen and other nutrients from the water brought in from run-off fertilizer, and plant decay. This inert substrate allows algae growth all year long, providing this important “mother’s milk” of small fish development.

Standing on a bank at Smith Mountain Lake, Michael Forte watched as Appalachian Power workers on a barge lowered what looked like a wooden pyramid the size of a small refrigerator into the lake.
Forte, of Franklin County, designed it himself, and now the invention is part of an assortment of habitat devices that will be used to determine how to entice more fish into coves at the lake.
With the help of Internet research, Forte built a similar pyramid habitat and installed it under his boathouse a few years ago. He said it caused a “dramatic difference” in the number of fish swimming in his cove; today, there are dozens and dozens as opposed to very few.
“I just wanted to see if I could attract some fish,” he said. “And it worked.” See the dozens of unique habitat models at fishiding.com
The power company, which uses Smith Mountain and Leesville lakes to produce electricity through a two-reservoir hydroelectric generation dam, hopes to duplicate that kind of success in drawing fish to shallow water areas, said Liz Parcell, a plant manager.
Last week, workers lowered about a dozen similar fish habitat devices in areas shallower than 20 feet in the cove below the Discovery Center at Smith Mountain Lake State Park in Bedford County.
“Fine, dense cover for the smallest of fish.
Some of the habitat designs were natural collections of brush and twigs; others were man-made and included cinder blocks, wood pallets and various pipes.
“It’s kind of like a scientific project,” Parcell said.
Some designs resembled objects that might be seen in art galleries, but that will change over time, she said. (possibly the fishiding structures)“They’ll get covered in algae; they won’t look like this for long,” Parcell said.
The goal is to study what designs work and then share that information with lake homeowners, who in turn could use it to create fish habitats of their own.
Next year, the Virginia Department of Game and Inland Fisheries will send scuba divers near the habitats placed in the water to gauge their effectiveness in drawing more fish, Parcell said.
The work is tied to the 30-year license renewal that the Federal Energy Regulatory Commission granted APCo in 2010, she said. The license, which the commission renewed after years of planning and debate among lake-area stakeholders, calls for a habitat-management plan and improved habitat along the shoreline.
Lake-area residents and landowners will have to obtain permits from the company before installing the habitats, Parcell said. APCo is working to have that process online, she said, and hopes to have it up and running soon.
“Hopefully, no one gets too excited too quickly,” she said.
I was recently contacted by J Harmon, President of the Protect lake Dunlap association in New Braunfels,Texas. He explained to me their struggle with the Guadalupe-Blanco River Authority over existing small diameter standing timber being hazardous to recreation use. Apparently, The GBRA has denied the cutting of these stumps to protect fish habitat and recommends marking these areas off to boat use which has the residents upset.
The PLDA’s plan is to draw down the reservoir and shorten the existing hazards about eight feet from normal surface elevation. I’m told there are hundreds of them and already have caused many accidents and property damage. J says the average depth is about 15 feet, so when cut, they would still stick up about 6-8 feet off the bottom, root ball intact.
After cutting, they plan to set one of our PVC habitat units on the remaining stump and fasten it there for good. This would increase the square footage of surface area approximately three times. The thinking is, with our units within six feet of the surface as water fluctuates, boats, skiers and water craft will be safe, including the fish. J and the group understand the benefits of not only keeping as much existing habitat as possible but to continue to add more habitat. The cut off tops would be kept and fastened to the remaining trunk too.
They have a full understanding of the science behind periphyton, nutrient removal and fish production and feel unwavering in their decision to work with only us in their efforts.
Senator Jeff Wentworth supports PLDA. With his intervention and the phone call from Gov. Rick Perry, GBRA’s action item #8 was tabled. The PLDA has been granted 30 days, (less now) to present their case for a final decision of what will be allowed. The General Manager and staff continue to meet with representatives of Lake Dunlap, enforcement officers, and fishery experts to evaluate the current no-wake area designation and alternative options to provide water safety and assure a balance of all uses including the preservation of fishery habitat and funding mechanisms, and to continue to review and develop alternatives that address congestion and lake boating conflict uses on Lake Dunlap and to report back to the Board at its next regularly scheduled meeting in August 2012.
What I’m asking of you once again is your opinion, hopefully your support. Can you find any adverse effects of removing these hazardous stumps as long as the habitat is replaced in other ways/forms? Can you comment on the benefits of the artificial habitat we produce and results you have seen? What can we expect to see in a 300 % increase in available cover for the fishery? With our help, the PLDA intends to present their plan for approval as a landmark decision for the state of Texas. Safety for the residents and fish is the priority of both sides, in that order. All parties involved want to save and increase fish habitat. Wood is good, just not where people get hurt. Send replies to either Jarod or myself at david@fishiding.com Thanks.
We have a new supplier of material to keep up with demand at fishiding artificial fish habitat products world headquarters in Woodstock Illinois. 30 yard containers of clean sorted siding are delivered to our facility two at a time, twice a week. That’s an average of 10,000 pounds of material per week.
Fellow construction and demolition contractor Ken Hoving, who has been supplying us with material for about a year and a half, helped set up this match made for the fish. These guys process material with a well greased flow to sort and re-use up to 80% of the material they bring in. In the past, as little as six months ago, all this material was destined for the landfill. Needless to say they are more than happy to see it going to such a could use to provide habitat for fish as well as removing excessive nutrients and converting them into fish food.
Bio film, Periphyton and algae grow on the inert substrate and begin the food chain. This natural occurring process mimics nature and cleanses the water of contaminants. This growth provides the “mothers milk” of nourishment for fish up to about one year old. Lasting underwater forever, this process only improves with more time.
The reusable experts
Started in October 2002 with just one truck and 30 boxes, Wendy Gold and her brother Robert Lenzini have modeled the foundations of their family’s generational business, Lenzini Excavating, initiating 37 years ago, into today’s MBL Recycling, established as an operation that specializes in the recycling of construction waste and demolition debris. Slowly but surely, the company has modestly added to its fleet, which now counts to eight trucks and close to 400 boxes.
Over time, the company has grown from its initial days of hand sorting to separate the waste material to a state-of-the-art facility that brings efficiency to the sorting process and new levels to both volume and productivity. The facility current stands at 41,000 square feet.
Based in Palatine, Ill., where the company’s new facility was developed in 2005, MBL Recycling offers full roll-off container services to its customer base, offering anywhere from 10 to 30 yard containers. The recycled material sorted, processed, source separated and is then sold back to the market. For example, recycled shingles are turned to asphalt in order to construct city roads. In 2007, MBL Recycling added concrete washout containers to its extensive line of services, further improving its position in the marketplace, tackling the market with a different style box, while the boxes also better comply with growing environmental standards.
Programs and services
The addition of 11,000 square feet to its new material recovery facility allows plenty of space for future growth.
And as its volume has continued to grow, MBL Recycling has seen an increase in incoming streams from diversifying construction projects, further adding to both the demand and specification of the waste separation. Because of such a high volume with its customers, MBL Recycling was able to hold its percentage in the market as the company successfully navigated the impact of the global economic downturn, which was specifically damaging to the American housing economy.
Business development
“Construction is really down here. Housing has come to a halt. We were pretty fortunate though because we never really focused much on housing,” said Robert. “We did a lot more commercial and it has slowed down…but nowhere near the housing.
“Will next year be any better? It is still too early to tell. We see it from an excavating side because we can tell when they bring in bids and how much work is there for the spring, and there isn’t much,” added Robert, illustrating that the excavating business allows for a unique secondary insight into the future.
“We pinch ourselves everyday that we are here and still going. We are riding the storm and doing everything status quo until everything bounces back. We’re always thinking of new things, but we have a couple hurdles here in Illinois that we are trying to work on now too (like getting into the drywall recycling market),” said Wendy.
“We were able to pick up some of the slack from some of the other guys that were in the housing market. The shingles this year also brought our tonnages way up,” said Robert. “Before we used to have to ship [the shingles] to Wisconsin and they used them in asphalt mix. Just in the last year, Illinois recognized this and got a standard for it.”
“We do a lot of work with Power Construction (based in Schaumburg, Ill.), a high profile contractor. We do a lot of hospital additions. We just finished the Northwest Community Hospital nearby and that was a huge project. Astellas Pharma is another Power Construction job. It’s a three-year project that just started this year,” said Wendy.
But right now our only out is that we recycle our own stuff, so that is our little niche.” Associated with the U.S. Green Building Council, MBL Recycling provides all LEED documentation for its customers, generating environmental sustainability reports on a monthly basis.
The transition to ‘go green’ is something that is becoming a “really big thing with the general contractors…they love to recycle, especially with some of the locations around us,” said Wendy. “Hooray for Chicago because they mandate 50 per cent recycling of construction. It is wonderful that they recognize that.” As such, in 2009, the Illinois Recycling Association recognized MBL Recycling as the Recycler of the Year.
Quality customer service
MBL Recycling prides itself on providing the best possible service to its customer base.
“Service is a big thing nowadays. People call and they want their stuff. It is not all about the pricing because at least when people call us they know we are going to be there,” said Robert.
“People are so thankful. You would be surprised at the phone calls—people go out of the way to call here and say something nice about one of our drivers, or for us being there in a pinch. Everyone gets the feedback and gets to feel good about things,” said Wendy. “We treat all of our customers the same—like gold.”

Researchers at Floating Island International (FII) in Shepherd, Mont., an agricultural region, are fishing nonpoint source nutrients out of 2.6-ha (6.5-ac) Fish Fry Lake. Bruce Kania, FII project development director, uses rod and reel to maintain floating treatment wetlands (FTWs) in the lake. Fishing is all part of the job; experienced anglers can catch one fish every 2 minutes at Fish Fry, he said.
The man-made floating islands transfer excess phosphorus from host water to periphyton, which is a colony composed of algae, bacteria, microbes, and organic matter. This colony serves as a food source for certain types of fish.In 2011, Fish Fry Lake removed 1.1 kg/ha (1 lb/ac) of phosphorus at a cost of $282/kg ($128/lb) and produced 112 kg/ha (100 lb/ac) of harvestable fish, Kania said. The lake’s clarity, measured by Secchi disk, improved to 5.8 m (19 ft) from an initial condition of 0.4 m (1.2 ft) with ongoing removal of suspended solids, according to FII. As of May, data indicate nutrient removal and catch rates are on their way to doubling in 2012, Kania said.

FTWs offer effective, cost-efficient additional treatment to increase nutrient removal. Application is universal — they are operating in various climates. FII has 4400 FTWs installed in such places as New Zealand, where water quality managers grow eels to restock other waterways, and in Singapore, Indonesia, and across the United States, including Alaska. The islands hold fast, surviving typhoons, tornados, and active icy waters, Kania said.Data show that FTWs have vast potential to address water quality and promote aquaculture. “We’re trying to answer the question, ‘Can we engender a viable fishery … to ultimately improve water quality?’” Kania said.
Mimicking Nature Fish Fry Lake has 530 m2(5700 ft2) of FTWs modeled after natural floating wetlands composed of peat and plants. Natural islands — such as an 82-year-old, 12-ha (30-ac) island in Chippewa Floage in northern Wisconsin — remove nutrients from water. Because Fish Fry Lake has several arms to it, there are two aerated floating islands and three small air diffusers (each 140 L/min [5 ft3/min]), which FII runs to increase the pond’s dissolved-oxygen (DO) levels to more than 6.5 mg/L and to stabilize temperatures below 24ºC (76ºF).

According to FII research, FTWs remove 93% of total suspended solids, 88% of phosphorus, 71% of total nitrogen, 88% of total organic carbon and chemical oxygen demand, 90% of copper, 95% of lead, and 36% of zinc. The data indicate that FTWs exceed removal rates of most comparable best management practices, such as retention ponds, wetland basins, media filters, and other manufactured devices.FTWs reduce algae, engender fish by growing periphyton and other biofilms, improve pond aesthetics, cool water, provide shade, and grow plants. FTWs can be used for effluent polishing, stormwater management applications, and lake restoration, Kania said.
FTWs can help a community facing increased effluent standards. “FTWs can be installed into existing [wastewater] lagoons to improve the contaminant removal rates, thereby resulting in cleaner effluent,” said Frank Stewart of Stewart Engineering (Bozeman, Mont.), who is an engineering design consultant for FII. “In most cases, installing FTWs into existing lagoons is cheaper than building new lagoons, especially if land costs are considered,” he said.

FTWs also could reduce peak discharges for occasional out-of-compliance wastewater dischargers, as well as decrease the volume of nutrients generated by livestock lagoons, Stewart added.Half the Cost While the systems do not work well in urban areas because of site restrictions, cities can get credit for contaminants removed from smaller upstream communities. “The cleanup effect for the river is the same, but the removal is much cheaper,” Stewart said.
According to Mark Reinsel of Apex Engineering (Missoula, Mont.), who establishes testing protocols and analyzes FII water data, FTWs cost less than 50% of traditional treatment, including alum. Floating islands cost between $269 and $484 per m2 ($25 and $45 per ft2), depending on whether aeration is incorporated. Plants, which increase longevity and stability, increase costs. Growing Fish FII has been using a recycled, nonwoven polymer matrix since 2006. The material also is used in other FTW models, such as freshwater coral, elevated bioswales, and docks. “It’s the best material we have for growing biofilm in the real world,” Stewart said.
Biofilm and periphyton love dirty water — the more of it in contact with the matrix, “the faster the biofilms remove contaminants,” Stewart said.
Adding aeration increases DO concentrations due to mixing, lowers overall water temperatures, and hastens periphyton growth, researchers explained. With increased sunlight and circulation, FTWs increase in size and density. As periphyton takes in phosphorus and transfers it to the fish that feed on it, DO levels rise and turbidity decreases. Sunlight reaches into lower levels of the water column, enhancing diatom?based periphyton growth. As FTWs grow, they become more diversified and stable, enabling them to remove more phosphorus and generate larger fish populations.
One aerated 230-m2 (2500-ft2) model in Fish Fry Lake circulates up to 2 m3 (72 ft3) of air per minute and 40 m3 (10,400 gal) of direct flow with a 2.25-kW (3-hp) motor. FTWs with aeration destratify the 8.5-m-deep (28-ft-deep) lake and homogenize temperatures when needed, Kania said.
Efficiency and Design Life According to Reinsel, FTWs “are more effective than treatment methods that are relying on settling.”Reinsel measures effectiveness in pounds of phosphorus per year per cubic foot of FTW. Rain gardens and stormwater retention basins are 20% to 30% effective, while the floating islands are 60% to 70% effective, he said.
Data on design life are sparse — FII’s oldest floating island is 8 years old. After 20 to 30 years, an FTW may have to be harvested.
The Art of FTW Maintenance FII harvests 12 to 18 kg (26 to 40 lb) of perch each week for consumption. “The perch fish fry is alive and well,” said Kania. “Our challenge on Fish Fry Lake is harvesting fish fast enough,” he added.
Fish Fry Lake has northern yellow perch, black crappie, and Yellowstone cutthroat trout. FTWs also can support tilapia, catfish, carp, freshwater shrimp, and minnow species. Photo courtesy of Floating Island Interantioanl. Click for larger image.
Other than all that fishing and frying, Stewart said FTWs are easy to manage.“Relative to eutrophied waters, catch-and-harvest needs to be the new mantra,” Kania said.
