Fish from ponds and ditch now accounts for 41 percent of total yearly production of 30.61 lakh tonnes.

A decade ago, its contribution was 34 percent, according to the Department of Fisheries (DoF).

Contribution of fish caught from rivers fell to 34 percent in fiscal 2010-11.

Declining fish habitat, the ongoing destruction of juvenile fish by using monofilament synthetic nylon fibre net and mosquito net, and environmental pollution are the major reasons behind the falling supplies of fish from rivers.

“An increased production and availability of fingerlings and hatchlings because of growth in hatcheries has played a key role in expansion of fish farming,” said Krishnendu Saha, chief fisheries extension officer of the DoF.

Over the past two decades, private investors established more than 800 fish hatcheries.

Their interest grew due to a business prospect against the backdrop of falling catches in open water areas and rising demand for fish.

Initiatives by the government and NGOs to motivate farmers also facilitated farming for common carp, pangus, monosex tilapia and shing (cat fish) in regions such as Mymensingh, northern districts, Jessore and Comilla.

Saha said many people in these areas entered freshwater fish farming because common carps (ruhi, katla, silver carp), pangus and tilapia become marketable in a short time.

It enables the farmers to gain higher profit from fish than growing crops such as paddy and jute, he said.

“Many people in greater Mymensingh have started fish culturing by making ditches in crop fields,” said Saha.

According to the DoF data, total pond area under fish farming was 2.42 lakh hectares early this decade, and such areas rose to 3.96 lakh hectares in fiscal 2010-11.

Production also rose to 12.70 lakh tonnes in 2010-11 from 11.40 lakh tonnes a year ago.

In fiscal 1999-2000, total production of fish from pond was 5.61 lakh tonnes, according to the DoF.

Sajjad Hossain, managing director of Joyda Aquafarm Ltd, said many people are engaged in pangus farming because it needs low investment.

Technologies were also easy for the farmers to follow, said Hossain of Joyda, which produces pangus fries at hatcheries, cultures those and sells to market.

The company produces 2,500 tonnes of pangus a year, he said.

M Mahfujul Haque, a professor of the Department of Aquaculture of Bangladesh Agricultural University, said the country has a huge potential to expand fish farming as only 11 percent of its pond resources have so far been exploited for fish.

In the past, fish was cultured in ponds by collecting hatchlings from natural sources. But the main breakthrough came since the beginning of artificial propagation, he said.

“Large investments have come in fish farming and some farms have gone for vertical integration,” said Haque

He said expansion of fish farming created job opportunities for many and augmented incomes of farmers. Some 25 types of jobs have been created because of fish farming, he added.

“The socio-economic impact of fish farming is huge,” said Haque, adding that many educated people entered such a farming failing to get jobs in the formal sector.

However, challenges are increasing. See the dozens of unique artificial fish habitat models at fishiding.com, the leader in true fish protection.

“Fries are not growing fast nowadays like the past. Inbreeding is also widespread,” said Hossain of Joyda Aquafarm.

At the same time, productivity of ponds is declining because of continuous farming in the same ponds.

“But production costs are rising because of soaring feed prices and other costs. It reduces profit margins,” he said.Sohel Parvez

Dear friends,

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.

See the dozens of unique artificial fish habitat models, fish attractors and fish cover at fishiding.com, the leader in proven science based, fish protection.

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.

A few weeks ago, my wife Renee’ and I took a trip to Shepherd Montana, headquarters of  Floating Island International Inc. We had been invited to stay on the ranch and to see for ourselves how Bruce Kania and his wife Anne, are growing huge fish fast with a woven matrix of inert substrates called BioHaven, or Floating Treatment Wetlands. I had been in contact with Bruce for some time, learning about how excessive nutrients brought in from runoff can be turned into fresh, tasty fish. Not only do the Kania’s grow fish, but frogs, minnows, pheasant, deer and all species of waterfowl prosper in their efforts. Even Yellowstone cutthroat trout flourish in this superior environment, along with crappie and perch and various minnows.

See the dozens of unique artificial fish habitat models, fish attractors and fish cover used at fishiding.com, the leader in proven science based, fish protection.

The setting was breathtaking, Mule deer and whitetail browsing on the thousands of perennial plants Bruce has planted for their benefit and soil stability. Over time these plants die off and return each spring, contributing to the rich organic soils being built up. Sprawling channels and wetlands run throughout the property, slowly beginning to filter and absorb the high levels of nutrients. When the water enters the property, it is dark and cloudy like chocolate.

Ducks of all varieties, geese, snipe, vulture, pheasant and more, have taken up residency in this oasis of prime habitat, with no intention of ever leaving. With Bruce being a veteran trapper, predators are being kept in check, protecting the desired species. With the Yellowstone River along one property line, this place is an outdoorsman’s paradise.

Stewardship of our natural resources is the core of the work being undertaken at Shepherd Ranch. We were there to catch and eat a bunch of these fish, helping them ultimately remove the phosphorus and nitrogen that causes excessive weed growth and poor water quality. Bruce and I dreamed big about someday soon, this concept of abundant, mass fish harvest to clean our Nation’s waters and beyond.

The data shows that over 50% of our Nation’s waterways are considered eutrophic and in trouble, meaning highly excessive weed growth and nutrient concentrations. Dark, stained and sometimes smelly water are all results of an unbalanced system. More information about our Nation’s waters are available on the National Fish Habitat Action Plan website, a wealth of details everyone is affected by.

When we began producing artificial fish habitat products made from reclaimed PVC siding called Fishiding, the ability to grow algae immediately on the inert surface area, appealed to the fisherman. Like myself, the average fisherman understands that habitat with good algae growth seems to hold more fish. It wasn’t until reading more and talking to Bruce that I began to understand the big picture of why this holds true.

These nutrients stick to surfaces underwater and create the beginning of the food chain called periphyton. Many forms of this wonderful natural, filter and food factory are present. Algae, bacteria, fungi, protozoa, zoo plankton and other invertebrates, function as a community highly efficient in capturing and processing nutrients. When I say processing, this means turning it into food of the highest quality found on earth. The more fish graze on it, it grows faster, decreasing bio mass and the fish grow at alarming rates, making the water clearer.

Numerous types of periphtyon are present, some require light to thrive and some do best in the dark. The more surface area available, the more periphyton can grow and work its magic. Pretend the floating island is a supermarket, the more shelves available the more food can be stocked for consumption. Small fish and fry eat this “super food” until about age one, when they begin to forage on larger minnows and bugs. Periphyton is the “mother’s milk” needed to start life full of nourishment.

This process has been perfected in second and third world countries. We are lacking in knowledge here in the states, but it’s improving with over 4400 of these floating treatment wetlands installed here and worldwide.

Think about all the ponds and lakes in your area. Golfcoarse ponds, retention ponds, private and public, there are many. Some are clear and deep with a balanced mesotrophic or oligotrophic eco system. The other 50% eutrophic waters, could be teaming with fish and every citizen is asked to help keep them clean…..by catching as many fish as you can eat, and removing them! The fish also reproduce faster than normal, so there is no worry of running out. Fish Fry Lake is living, thriving proof of this for all to see. Renee’ and I caught over 500 fish in less than eight hours of fishing. If your hook was in the water, it was being attacked by one or more gorgeous perch or crappie. From 6-8” one year olds, to 12-14” plus jumbos! Remember, this is in Montana not Lake Michigan, the only other place I have ever seen perch of this size. Perch and Crappie were abundant to say the least, with a perch containing about one percent live weight of phosphorus. The name “Fish Fry Lake” more than lives up to its name. Remember, this works with no chemicals, win,win,win…….

This natural cause and effect has other uses too. Bioswales also made by FII,  are used in ditches and swales to slow down erosion as water runs through it, similar to adding hay bales in a ditch after new construction. The difference in using the inert matrix, patented by FII, is that as the bioswales slow down the water, the periphyton forms and begins to consume the over abundant nutrients, cleaning the water as it passes through slowly. Unlike the hay bales, the matrix never breaks down, which would add to the nutrient load in the waterway. Same with weeds, as they decompose, they remove oxygen from the water and add fertile organic matter that acts like fertilizer. Inert substrates like the matrix material used in the Floating islands, never breakdown and keep working year round to feed the fish and clean the water.

One of the optimal ways that FTWs can transition nutrients from water to beneficial use is to grow bacterial biofilm rather than floating algae.  Bacterial biofilms grow faster than algae when their limiting parameters are satisfied, and when they have adequate circulation and surface area for growth.  With appropriate stewardship, they also are an improved primary food source for fish (Azim 2005).

Circulation increases bacterial efficiency by bringing nutrients such as dissolved oxygen, nitrogen and phosphorus to the biofilm.

A single 1000-square-foot BioHaven Floating Island can provide over 18 acres of strategic “concentrated wetland effect” surface area.

As demonstrated in field-scale case studies, waterways containing FTWs remove contaminants (pollutants) such as ammonia, total nitrogen, total phosphorus, Total Organic Carbon (TOC), Biochemical/Chemical Oxygen Demand (BOD/COD) and total suspended solids (TSS).  These studies have included municipal wastewater, storm water, lakes and agricultural runoff.  FTWs have demonstrated the ability to simultaneously remove all of these contaminants, due to their complex biofilms containing both aerobic and anoxic bacteria.

Dissolved oxygen (DO) levels are higher when inert substrate are used rather than organic substrates like wood, due to oxygen consumption during organic carbon uptake by biofilms.  Inert substrates like BioHaven polymer matrix, can provide a more precise ability to initiate movement of a waterway’s nutrient load up the food chain. Periphyton moves nutrients up the food chain better than does synthetic fish food.

The bottom line is this. To ultimately remove these unwanted nutrients, fish have to be harvested. Not all lakes have these issues, but in Eutrophic lakes, the fish contain these nutrients and have to be caught and eaten to keep up with the periphyton growth. A perch for example, contains about 1% live weight of phosphorus. By removing enough fish to equal one pound of this chemical which is safe for humans and needed for strong bones, about 700 pounds of aquatic vegetation never gets a chance to grow. No chemicals or weed harvesting just fishing and keeping them for the table. Would you be willing to help clean your neighborhood pond by catching and eating some fresh fish? It’s a reality and is being performed at an alarming rate at Fish Fry Lake. We flew home with only one checked bag, 50 pounds of fresh fillets.

Clean water  entering the Yellowstone River and ultimately the Mississippi, Stewardship is the lesson to be learned.

What kind of habitat helps the fish grow large and the water stay clear? Can you actually dictate where to cast your lure to find a bass lurking in the shaded cover like a defensemen reads a quarterback?

If you spend the time and effort to plan the design of your lake or pond from start to finish, you can achieve these goals and much more. Chris Kelsay, veteran linebacker/defensive end of the Buffalo Bills has a passion for more than just football. Chris not only loves to tackle running backs and wide receivers, but big bass are also on the hit list. Growing up in Nebraska, Chris has loved the outdoors all his life. When he’s not playing ball, he’s often talking fishing and hunting with his family and friends, planning his next adventure with his bow, firearms or fishing rods.  Chris plays off the field with as much intensity as he does at work, stalking, sneaking and outsmarting his opponents with hard work and dedication.

Another NFL great that is no stranger to the outdoors is Aaron Graham, former Center for the Arizona Cardinals, Oakland Raiders and finishing up his career with the Tennessee Titans. These two guys have quite a bit more in common than playing ball in the NFL. Not only are they neighbors near Gretna Nebraska, but they both love to fish and hunt, having their own private lakes that they enjoy with their families and friends. Both these guys played college ball for the Nebraska Cornhuskers, as well as Chris’ brother Chad. Retiring from the NFL, Aaron now owns and operates his own company called “Premier Outdoor properties”, which specializes in large tract farm, ranch and recreational real estate throughout Nebraska, Kansas, Iowa and Missouri. Participating with Cabela’s Trophy Properties, his firm can help you find your dream  hunting and fishing, farm and ranch, lake or river frontage, and large tract acreages, to meet any needs you may have.

Aaron has had his lake stocked with an exceptional strain of bass, with catches to date over eight pounds by his son Cooper. With the lake being about seven years old, Aaron has a jump start on Chris with some experience in habitat, stocking and water quality. We met Aaron over a year ago, providing him with some of our artificial fish habitat products for his lake. Follow this link to read about aaron’s habitat project. The success he has had with our products, encouraged him to put Chris in touch with the team at Fishiding.com to discuss a plan for his first of two lakes, as it was getting ready to be filled to full pool. With a large well, levelor system, aeration and a stocking plan in place, we came up with a plan and design to meet Chris’ desire to create a personal, one of a kind fishery. The first  lake Chris has on his property, at just over six acres, needs  plenty of cover for the fish to spawn, hide and hunt within. A well known and respected fisheries biologist Bob Lusk of Pondboss.com, recommends at least 20% of the surface area of a lake or pond be provided in habitat.

See the dozens of unique artificial fish habitat models, fish attractors and fish cover used at fishiding.com, the leader in proven science based, fish protection.

With plans to include aquatic plants, wood and rock, we came up with an array of artificial habitat models to make up about 25% of the needed habitat for Chris’ first lake. We have always felt that a variety of natural and artificial habitat provides the diversity, all types of fish species need to utilize throughout the year. Like most things in life, everything in moderation seems to achieve the maximum efficiency and ultimate benefits for a fishery.

The plan we came up with provided an array of structure textures, sizes and shapes to best provide cover for fish spawning and growing habitats. A total of 350 individual habitat units were hand selected to best achieve Chris’ goals to create a trophy bass fishery. A key element to any habitat plan is to create a line of structure from shallow water spawning areas out to mid depth and ultimately deep water cover. This allows young fry to hide in fine, dense cover immediately after hatching, in the shallow water they are spawned in. As these young of the year fry develop and explore out to mid depth ranges, they need to have cover to utilize as they progress deeper. If this cover is not available, they get eaten before reaching preferred size by predator fish. It is imperative that these small fish are able to hide and grow larger to the 3″-5″ size before becoming forage for the game fish. A bass for instance, needs to eat 10 pounds of forage to put on just one pound in weight. If that bass eats the fry before they get large enough, he will eat them all up just to satisfy his hunger and desire to put on weight.

We put our plan together to deliver the structure and help Chris with the installation. Although artificial habitat only needs to be installed once, this was a large amount of structure to ship and install at one time. It was decided we would drive the almost 7200 pounds of habitat out in our own truck and trailer from our facility in northern Illinois. The 475 mile trip had us arriving by lunchtime on a Friday, with the hopes of finishing the installation late Saturday evening, for the return trip on Sunday.

Three of us set out at 4:00 a.m. Friday to achieve our goal. Our son Graham, an electronic media/photography major at Moody Bible Institute in Chicago, came to capture the project in high definition pictures and video and help with the installation process. Also along was our nephew Josh Fick, a starting player for the North Central college football team, over excited to meet and work with the NFL players. Meeting us there was Josh Milczski, a Nebraska native, writer for recycled fish.org, a pond boss moderator and Nebraska Fish and Game board member to lend a hand and share his knowledge. Also on hand to help was Chris and Chad Kelsay, as well as Aaron and Cooper Graham.

We unloaded all 350 units and spotted them around the lake per plan Friday afternoon and then when out for a well desreved Nebraska steak dinner to re-fuel for the big push on Saturday.

The weather was un-seasonably hot, with temps. in the low 90’s and full sun. None of us expected to be getting sun burn in march, let alone starting to find Morel mushrooms already. The turkey were gobbling on the roost as we set up for a long day of work, unfolding each unit and stocking them on the bank near their final resting place. Geese and ducks of all varieties, came in and out of the lake all day, giving us a show of the abundant wildlife in the area. There was about 2 feet of water existing in the lake from runoff and ground water level, an ideal situation to put our plan into motion.

The “Kelsay express” saved lots of time

The Fishiding fish habitat products are all made from reclaimed PVC vinyl siding that was destined to be put in landfills. Over 50% of the material  acquired has never been used on buildings and will last for many generations to come. This safe, inert substrate, works perfectly for underwater applications in fish habitat. Our main supplier of  discarded siding comes from  K. Hoving companies. This state of the art waste removal operation currently recycles an astounding 75% of the trash they collect. Re-use is the term they use to explain their company goals. See this story about their firm and the great things they are doing to help our environment. Add the cover and your fish will prosper, Go-Green and save the environment all at the same time.

All fishiding units come complete, ready to sink with no assembly or additional parts/tools needed. Simply open the box, bend to any desired shape and toss in the lake. Each unit sinks upright with the included “stump like” base. There is no incorrect or wrong shape, as diverse as Mother Nature. Artificial habitat products are being used all around the country, as biologists learn more about the many advantages they offer. Years of use from these structures allow anglers and pond/lake owners a snag free habitat for fish to utilize. Saving the environment, these fish attractors help conserve energy with no manufacturing process involved.

Cleaned, cut into various shapes, widths and sizes then cemented into just about any type of safe container, fishing groups are getting involved in creating new habitats lost from degradation and development. All of the fishiding models are available shipped loose as well as in a completed form. Customers can save money by purchasing loose pieces of the PVC in all varities and create their own custom designs by using their own container and cement. A special mixture of cement is also available to ensure a tight, fool proof bond to the vinyl. The pieces and models come in an array of colors, just like the colors available when siding your new home. After the algae and bio film begins to grow, they all take on a greenish/brown appearance.

Groups like the B.A.S.S. Federation Nation have begun to incorporate Fishiding habitat products into their ongoing conservation efforts. Projects in West Virginia were recently completed with great success. Plans to work in New Mexico, South Dakota,Virginia and Texas are being put together currently with the conservation directors in those states. The B.A.S.S. Federation Nation  leads the industry by example in conservation work with groups in all states and Canada promoting conservation and water quality issues world wide.

Lake and pond owners enjoy the ease of installation, with no need to ever replace. The limbs all have any holes or notches removed to make each unit  snag resistant,unlike brush and Christmas trees. By providing shallow habitat for fry and forage fish, mosquitos can be almost eliminated in the area, as they feed on these pesty critters. Shallow habitat is the key to growing your own forage base, thus eliminating the need to constantly restock minnows to feed your game fish.

100 Keeper models were incorporated into the plan for deep water structure. These large units each boast over 62 square feet of surface area  and allow predator fish to hunt and hide around. When opened and bent to shape, they cover a seven foot diameter and are best installed with about a foot of space in between. This allows fish to navigate through them, feeding and resting in the shade they produce. Bass prefer the dense cover and shade that these fish attractors provide.

Also part of the plan was to install 25 Stakeout structures, which are  artificial stake beds, crappie and bluegill fisherman use a great deal in the south. These units stand 48″ tall and have an open grouping of individual “sticks” that the panfish prefer. Another 50 smaller prototype versions of these were installed in shallow areas for young of the year fish to navigate through as well.

With all the help and planning, we were able to meet our goal and finish installing all 350 Fishiding habitat units by sundown on Saturday. Chris welcomed us into his beautiful home and surrounding landscape. Although we had no time to hunt or fish while we were there, plans are being made to come back to install our habitat products in his second, five acre lake. With common goals of preserving our natural surroundings and creating a fantastic fishery, we are planning to spend some time together in the great outdoors with bows, guns and fishing rods in hand. New friendships have been made, stories of the hunt continue to be shared and the love of the great outdoors continue to be the catalyst for a common bond between men from all walks of life.

Before and After habitat

The concept of including fisheries management in strategies for water quality improvement is not new, but floating islands give the notion a boost. The simple concept is, add lots and lots of substrate and the fish will come! Catch plenty of fish and you will sequester the unwanted nutrients in a more appropriate part of the eco-system – lunch!

Lake Management Services:

“It is important to take a proactive approach on the management of your lake. It is not usually the case that you stock the lake with fish and never need to further maintainence. Aquatic environments change making it imperative to pay close attention to the lake and see the signs of problems before they become to severe.”

How Do We Aerate a Lake Properly?

Fish Stocking:

Fish can be stocked throughout Central Texas at all times of the year with few exceptions for certain temerature sensitive species. Stocking your lake is the most rewarding and important decision when establishing your ecosystem. While it’s easy to get carried away and go straight to adding Gamefish, don’t forget to start with the basics and establish your bait fish. Often times, people are impressed with how quickly they are able to see a return on their investment when they take the time to establish their food chain appropriately from the beginning.

Vertebrates Removed by Mechanical Weed
Harvesting in Lake Keesus, Wisconsin
TRAVIS L. BOOMS

INTRODUCTION
Mechanical weed harvesting has been used to control nuisance vegetation in Lake Keesus since 1979.

Fish, turtles,and amphibians often become entangled in the vegetation
and are incidentally removed from the lake while harvesting
weeds. See the dozens of unique artificial fish habitat models, fish attractors and fish cover used at fishiding.com, the leader in  science based, proven, fish protection.

Mechanical harvesting removed 2 to 8% of the standing crop of juvenile fish in harvested areas in Saratoga Lake,New York (Mikol 1985) and 32% of the fish population in
harvested areas in Orange Lake, Florida, representing an
estimated replacement value of $6,000 per ha (Haller et al.
1980).

Engel (1990) found mechanical harvesting removed
21,000 to 31,000 fish per year from Lake Halverson, Wisconsin, representing 25% of the fry in the lake. Little other current information has been published concerning aquatic vertebrate removal by mechanical weed harvesting in Wisconsin.

SPRINGFIELD MO — The Missouri Department of Conservation (MDC) and the University of Missouri are working together on a radio-telemetry study that will provide information about behavior and habitat use of largemouth bass.

Tracking of the tagged fish will begin this month (May) and will continue through 2012. Each fish will be located once per month during daylight hours. Once every three months, a smaller number of the tagged fish will be tracked for a full 24-hour period to monitor daytime and night-time movements. Once each fish is located information will be recorded such as GPS location, distance travelled from last location, depth and habitat use.

Earlier this year, 60 legal-size (greater than 15 inches) largemouth bass were collected from the Kings River arm of Table Rock and surgically implanted with radio tags. After the fish recovered from their surgeries, they were released back into the lake.

A tagged fish can be identified by a radio-tag antenna coming out of the body cavity and sutures near the fish’s abdomen. Besides a radio tag, each bass in the study was also tagged with an orange tag near the dorsal fin. This tag has a five-digit number unique to each fish. Anglers who catch tagged fish should contact the MDC at 417-334-4859 or e-mail MDC Fisheries Management Biologist Shane Bush at shane.bush@mdc.mo.gov.

When reporting a tagged fish, individuals should provide:

• Number from the orange tag.
• Length and weight of the fish.
• Location the fish was caught (GPS coordinates if possible).
• Overall condition of the fish.
• Approximate depth the fish was caught at and if it was near a habitat structure (if known.)
• If the fish was released or harvested.

This study is part of the Table Rock Lake National Fish Habitat Initiative, a project designed to maintain and improve fish habitat in Table Rock.

Since 2007, the MDC has placed more than 1,500 fish habitat structures in the lake. These structures were marked using GPS. Locations of these structures can be found athttp://newmdcgis.mdc.mo.gov/tablerock.

The NFHI project is a joint effort of the MDC, the National Fish and Wildlife Foundation, Bass Pro Shops, the U.S. Army Corps of Engineers and other organizations. It is a pilot project for a broader national program focused on habitat protection and restoration in reservoirs throughout the country.

A new study by the U.S. Fish and Wildlife Service says the potential for damage to fish habitats in the Driftless area of Wisconsin, a hilly region in the state’s southwestern reaches, is great, and the damage may have already been done. The findings come from a national survey of fish habitats released earlier this month.

DRIFTLESS FARM (PHOTO BY UW-STEVENS POINT) 

The Driftless area spans about 24,000 square miles and includes portions of southwestern Wisconsin, southeastern Minnesota, northeastern Iowa and northwestern Illinois, according to the agency. Because the region wasn’t raked flat by the last continental glacier, it’s full of rolling hills and spring-fed streams.

“Just minutes northwest of the state capital, the roads curve gently and the hills begin to rise invitingly,” said a recent story in Milwaukee Magazine. “Before long, there are Holsteins and horse farms, an occasional orchard, a flock of sheep as pale and fluffy as an earthbound cloud.”

The region’s agriculture, however, may be a detriment to its native fish habitats.

Using a variety of factors – including the presence of urban development and the density of farming, livestock, industrial pollution sources and habitat “fragmenters” such as dams and road crossings – the study calculates the risk for “fish habitat degradation” in watersheds.

DRIFTLESS AREA (BY NATIONALATLAS.GOV) 

Most of the state’s southern half is said to be at “high” risk of degradation, but the largest swath of “very high” risk lies in the Driftless.

According to the Fish and Wildlife Service, “Poor land and water management practices including intensive row crops, fertilizer use, channelization, water withdrawals, loss of perennial vegetation and invasive species have caused excessive stream bank erosion, sedimentation and poor water quality.”

The affected area includes the Mississippi River. The Driftless pollution impacts its waters “all the way to the Gulf of Mexico,” according to the study, contributing to low oxygen levels downstream.

The federal agency isn’t saying the region’s waterways are damaged or not, only that there’s a “very high” probability that they already are.

As reported in NewsBuzz, the state Department of Natural Resources recently caught a grass carp, a plant-devouring invasive species, in the Lower Wisconsin River within the Driftless area. Officials believe it had migrated from the Mississippi River during a period of spring flooding.

Trout Unlimited, a national nonprofit funded by sport fishermen to support conservation, has organized the Driftless Area Restoration Effort to “protect, restore, and enhance rivers and streams for fish and other aquatic life throughout the Driftless.”
