Debris from the recent tornado that swept through Oklahoma is already being put to use by state conservation officials, who are submerging it in lakes to form “fish attractors.”

Cinder blocks scattered by the twister that killed 24 last month have been collected by the Oklahoma Department of Wildlife Conservation, which will use them to make what anglers call “spider blocks,” to sink in state lakes, according to The Oklahoman

“We’ve probably got close to 500 right now,” Greg Summers, of the Oklahoma Department of Wildlife Conservation, told the newspaper. More habitat articles at fishiding.com

Fish congregate around the spider blocks, which get their name from the appearance given by the PVC pipe that sticks out from the cinder blocks.

“Predators use them as an ambush point,” Summers said. “That’s why they are valued as fish attractors because they do attract predators.”

Spider blocks are usually placed at depths of 12 feet or less, and marked for anglers.

TPWD stocks stripers at PK Lake

In an effort to continue to increase the fish population at Possum Kingdom Lake, Texas Parks and Wildlife Department stocked 100,000 striper fingerlings May 30. The fish arrived from the new TPWD East Texas fish hatchery in Jasper. They were then transported by boat from North D&D to deeper water before being released into the lake. “We use the deep water transfer to help avoid predators that are usually close to the shoreline,” said Steven Hise, TPWD staff member charged with the job of transferring the fish. According to Wes Studder, TPWD senior technician, the stocking was done following a work project which sank cedars and brush piles to increase fish habitat in the lake. “The new brush piles will provide shelter for the new fish,” he said. “It is great to have a group of people to work with on projects like this.” TPWD is working in conjunction with Hell’s Gate Bass Club on projects to improve the lake. Plans to coordinate with the club were made after an April HGBC meeting where members voted to establish a chapter of Friends of Reservoirs. The program will enable the club to obtain grants and donations for projects done in conjunction with TPWD. TWPD also plans to start 60 small colonies of American pond weed and water willow in the Cedar Creek area of the lake. “We have plans to return to the lake in June to establish vegetation habitats,” said Studder. “It will give us another chance to work with the Hell’s Gate Bass Club.” Dropping water levels and the age of the reservoir have resulted in fewer habitats and less natural plant growth that acts as a refuge for younger fish. To battle this, TPWD began a habitat enhancement project. Its goal is to create natural and artificial habitats, as well as re-introduce aquatic vegetation into the lake creating safe places for young fish. By Sarah Howard.

NORFORK — The North Fork of the White River and the scenic valley that cradles it are expected to offer some new accommodations for fish and humans by the summer’s end.

An award-winning team of biologists is set to begin work in the riverbed, strategically placing a series of boulders and root wads in the stream for fish habitat and bank stabilization.

Meanwhile, an Arkansas Game and Fish Commission construction crew is building a new scenic overlook on the east side of AR Highway 5 to the north of Norfork.

Fish habitat

AGFC Biologist Tim Burnley told The Bulletin the river work is a second phase of the North Fork River Habitat Project that began in January 2012.

The work involves about 1.5 miles of riverbed and riverbanks from the head of Cooper’s Island downstream to waters fronting River Ridge Inn. Burnley said the stretch of river below Cooper’s Island — known to anglers and biologists as The Flats — hasn’t contained many objects to create holding places for fish, also known as “lunker bunkers.”

“We plan to come in with in-stream cover — mostly rocks and rootwads,” Burnley said. “With that and new water from minimum flow, we expect to have some good fishing in this area of the river.”

Burnley heads up the $100,000 project with AGFC biologists Tony Crouch and Eli Powers.

A series of large boulders is planned for placement at the head of Cooper Island to offer some floodwater protection for the natural island structure and, at the same time, create new holding places for fish.

A similar series of boulders was placed on Charlie’s Island in the first phase of the project.

Overlook project

Mike Cantrell, coordinator of AGFC’s Calico Rock Regional Maintenance, leads an AGFC team in construction of a new public overlook on the east side of Highway 5 just north of its intersection of AR Highway 341.

Cantrell said the overlook will offer a much broader view of the river valley than can been seen from an unmarked pull-off to the north of the new overlook site.

A platform is planned for sightseers with disabilities.

A second viewing site higher on the ridge is planned for hikers. Parking for up to eight passenger cars or trucks is planned, but not for buses due to a relatively steep grade to the parking area, Cantrell said.

The material cost for the overlook is about $27,000, Cantrell said.

Both projects are funded mostly through the U.S. Fish and Wildlife Service’s Sport Fish Restoration Fund administered by AGFC. That fund matches $3-to-$1 a contribution of $25,000 for the fish habitat project from the the state’s Overlook Estates Settlement Fund held jointly by the Arkansas Department of Environmental Quality and Trout Unlimited.

Award-winning work

Burnley‘s group and an array of contributors including the U.S. Fish and Wildlife Service, Explorer Scouts, Trout Unlimited, the U.S. Army Corps of Engineers and the Friends of the North Fork Fish Hatchery, are 2010 recipients of the American Fisheries Society’s Sport Fish Restoration Project of the Year Award.

The project included substantial stream-bed and bank stabilization for Dry Run Creek with major access for anglers with disabilities.

What Exactly Is Fish Habitat and Why Must We Care?

What Exactly Is Fish Habitat and Why Must We Care?Thomas E. Bigford

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.

IMG_0604Fish Fry Lake may be the best fishing hole in Montana…at least for kids!  The lake is only 6.5 acres, but the water’s invitingly clear and it is extremely easy to catch yellow perch, crappie and bluegills.  Even some Yellowstone Cutthroat trout happen here…which may be their easternmost extension.  Fish grow fast in this lake at Floating Island International’s headquarters 25 miles from Billings, Montana.  Fish Fry Lake is a test site for BioHaven® floating islands as well as other embodiments of BioHaven technology.Last year over forty kids (and a couple adults) caught their very first fish on the lake.  For most of these fisher people it was as simple as attaching a piece of nightcrawler onto a small jig head, then flipping the baited hook into the crystal clear water and watching their line for some indication of a bite.  Typically the line will twitch when a fish picks up the offering, and then it’s a straightforward process.  Lift the rod tip and reel in a scrappy panfish.  Some kids start off with a cane pole, just like I did way back when.  Today there’s even lighter fiberglass extension poles and it’s pretty easy for little guys, and gals, to swing the offering over open water, wait a moment, then pull up a seriously exciting fish!The pond is also home to painted turtles, leopard frogs, bullfrogs, tadpoles, blue herons, mallards, wood ducks, teal, spoonbill, widgeon, yellow and red headed blackbirds, woodpeckers, garter snakes, the occasional bull snake, crawfish, salamanders, Canada geese, osprey and even the occasional Bald Eagle, all of which tend to be of great interest to kids.  As I was growing up there was a similar wetland within walking distance…and kid tracks along the shoreline evidenced fascination with critters and plants, and pretty much everything wild.  Episodes with poison ivy notwithstanding, kids and water and fields and wildlife, they used to go together as naturally as water flows downhill.  Today though, computers seem to have taken over some of that space, some of the territory that used to be reserved for kids and nature to get to know each other. 

We are not against computers!  The advances associated with the huge strides in information transfer technology that we’ve experienced in the last twenty years are life changing, and mostly positive.  But wouldn’t it be ideal if we could retain some connection with nature?  And certainly not just on a computer screen, but in person and up close!  Catching a fish, splashing after a leopard frog, or sneaking up on a big old gander goose is the stuff of childhood, and I don’t think it’s a good thing to miss out on.

I remember a troupe of kids passing by with fishing rods in hand one day last summer, when one of the boys, lagging behind, complained about the sun being “too hot!”  A young gal in the group suggested he “man up”, at which point the young lad was pretty much forced by the amazing power of peer pressure to deal with conditions.  Not sure if those kind of life lessons happen frequently in front of a computer screen.

And kids don’t catch fish automatically.  Not even on Fish Fry.  They must learn the process, think it through, and then connect the dots.  Along the way, with a bit of patience, they are rewarded.  This is good stuff for kids.

There was a young gal that could not handle touching a worm.  When it came to touching a fish, that was at least as bad as the idea of touching a worm.  An hour later she was independently doing both.  Real life lessons, and a new connection with where food comes from.  More good stuff!

Today the majority of fresh water lakes in the U.S. are so nutrient rich that they are at risk of running out of dissolved oxygen, without which fish die.  Fish Fry Lake has turned this condition on its head.  We have learned how to cycle those same nutrients into fish, instead of algae.  Catch rate on Fish Fry is a fish every two minutes on average.  The 6.5 acre lake yielded 5,168 fish last year, which translates to 210 pounds of fish per acre.  And along the way the water in Fish Fry was kept within Cutthroat Trout temperature requirements.  A nearby public lake, with conventional management, yielded about ten pounds of fish per acre.  And those fish were stocked, while Fish Fry’s are wild and naturally reproductive.  In late summer, the bottom half of the public lake is devoid of breathable oxygen.  Trout that were stocked in that lake in the spring have a choice…they can cook in the warm water on top, or suffocate in the stratified cooler water below.  The same conditions repeat themselves in thousands of U.S. waterways every summer.  But it doesn’t have to stay this way.

What if we focussed on our public waterways, especially in cities and villages?  What if we took that water and cycled the nutrients that are already there, into fish?  This is a very real prospect.  We do have the science, and we have the tools.  Dive into our website and keep this vision in mind…of kids catching fish hand over fist.  This is a new vision of abundance, and it’s within reach.  We can concentrate nature’s wetland effect and the result is an upward spiral that leads to both clean water and huge abundance of healthy, vibrant and edible fish.

Following are a few Thank You notes by kids who’ve fished here on Fish Fry:

Dear Ms. Anne and Mr. Bruce.

Thank you for letting us go to Floating Islands.  It was a lot of fun. I loved catching fish.  It was fun.  I like your dogs.  I think the picnic was fun, too.  I think I learned a lot about fishing.  You made my day.  Thank you for everything.
Thank you for letting us fish and play with the dogs.  I caught four fish.  It was awesome!  The floating islands are really cool and I hope to come back again.
I liked….. fishing, seeing the fish.  Thank U.
Thank you for letting us fish for different kinds of fish.  I enjoyed fishing.  I also caught a ton of fish within the small amount of time I spent fishing.  I also enjoyed walking on the floating islands.  I really enjoyed throwing frisbees for the three cute dogs….. I thoroughly enjoyed going to Floating Islands and I hope to come again.  Thank you very much.

The unexpected consequences of fighting Eurasian Watermilfoil, preventing fish from successfully reproducing?

Lake on the Brink:

The unexpected consequences of fighting Eurasian Watermilfoil

By Eric Engbretson

 

 

In 2012, Greg Matzke, a fisheries biologist for the Wisconsin Department of Natural Resources, made a startling discovery on Florence County’s Lake Ellwood. During a comprehensive fish survey which included spring, summer and fall netting and electrofishing surveys, Matzke discovered that all of the lake’s largemouth bass were older than 5 years of age, with approximately 91% of the largemouth bass population being at least seven years old.  The absence of younger fish indicated a recruitment failure for a number of years.  Such failures in largemouth bass recruitment over multiple years are unprecedented in the state of Wisconsin.

 

“The current largemouth bass population is in serious trouble,” Matzke reported. “It appears that natural reproduction of largemouth bass has not occurred since 2007. As these older/larger fish move through the population, a significant reduction in largemouth bass abundance will take place, with the potential for the complete loss of this species of fish unless the current situation changes.”

 

Matzke next began looking at the lake’s panfish population.  What he found was stunning. Overall, the lake’s panfish abundance had fallen an estimated 75% in just the last 10 years, with bluegill and rock bass abundance down an estimated 65% and 89% respectively, showing that these populations also appear to be collapsing. Intense sampling throughout 2012 found only a single black crappie under six years of age, showing another alarming recruitment failure in several consecutive years. When Matzke analyzed the ages of Lake Ellwood’s northern pike population, the results were even more disappointing: There were no pike under the age of eight!

 

Matzke stared at the data he had collected. His department had never seen a mystery like the absolute and complete recruitment failures of native northern pike, black crappie, and largemouth bass (along with significant reductions in recruitment of other panfish populations). He shared his findings with other fisheries professionals across the state and they all said the same thing.  They had never seen a collapse like this in their careers. Matzke and his team scrambled to collect more data and tried to find a cause that could have brought the fish to the brink of extirpation in Lake Ellwood. Surveys from 2002 had shown normal abundance, size structure, growth, and recruitment in all of these species. What had happened in the last ten years that was preventing fish from successfully reproducing?

 

The only thriving species of game fish in the lake were smallmouth bass. Their abundance and size structure had grown in the last decade and recruitment was high.  This suggested that the problem was targeting specific species of fish. Because Lake Ellwood’s smallmouth bass were doing so well while the other species were collapsing, the focus turned to the lake’s historically sparse but important aquatic plant community. All the species showing recruitment failures are highly dependent on aquatic vegetation for spawning as well as cover and food for their young. Matzke observed that smallmouth bass seem to be different. “The fact that this species was not affected by the reduction in plant life,” he said, “is not a major surprise since as a species smallmouth bass are less dependent on aquatic vegetation.”

 

The Smoking Gun

 

Eurasian Water Milfoil was discovered in Lake Ellwood in 2002. Herbicide treatments began in 2003 and increased every year. By 2007 recruitment of northern pike, largemouth bass and black crappie had come to an end. “When I started to analyze the data it was strikingly obvious to me that there are some problems associated with the herbicide”, said Matzke. When he graphed the fish abundance (by year class) over the last decade and overlaid it with a graph showing yearly herbicide treatments, he found what he believed was a critical connection.  Fish numbers fell as the amount of herbicide increased.  Interestingly, in the year following a relatively low application of herbicide, young bluegill (and black crappie to a much smaller degree) began to appear again, but their numbers are still very low and they will likely disappear before they reach age 2.

 

 

 

Year class strength, indexed using age estimation to determine number of individuals of each year class captured during a 2012 comprehensive survey, for northern pike, black crappie, largemouth bass and bluegill plotted against the number of pounds of 2,4-D (not acid equivalent) used to treat aquatic plants in Lake Ellwood, Florence County, 2003-2012.

 

 

 

“We still wonder which stage of reproduction has failed in these species”, says Matzke. “Aquatic vegetation plays a major role in spawning site selection and in the survival of eggs and fry. Plants are also the source of primary production providing food and habitat for young fish and prey items, including invertebrates and minnows. It seems likely that one or all of these important phases of reproduction are dwindling in Lake Ellwood.”

 

On April 17, 2013 Matzke met with the Lake Ellwood Association to reveal his data and conclusions. He told the group, “The main cause for failed northern pike, largemouth bass and black crappie recruitment (along with the massive reduction in panfish abundance) appears to be the loss of aquatic vegetation.” The 2-4-D herbicide used on Eurasian watermilfoil had been successful in reducing the abundance of this invasive species significantly. Conversely, other native plants were also harmed by years of chemical treatment. Matzke said he has no reason to believe the chemicals have directly caused a failure in reproduction of any species of fish in Lake Ellwood. However, Matzke does believe that the chemicals have indirectly caused recruitment failure by eliminating too many of the aquatic plants young fish need in order to survive.  Matzke has called for a change in the way the Lake Ellwood Association has been managing the lakes aquatic plants.  He recommended that further chemical treatments for milfoil be stopped.

 

“First and foremost,” says Matzke, “we need to promote and strengthen aquatic vegetation in Lake Ellwood.” He stresses the role of aquatic vegetation in spawning and concludes that the loss of vegetation (including the invasive milfoil) has almost certainly wiped out a great deal of forage for young fish.

 

It seems that milfoil treatments controlled the invasive plant but also jeopardized the health of the lakes fishery. Today the lake contains a dwindling and rapidly aging population of largemouth bass, black crappie, northern pike, and bluegill. Matzke hopes the plants will come back in time for the remaining old fish to produce at least one year class before they die. If that doesn’t happen, many fish populations will likely be extirpated from Lake Ellwood. New fish can be stocked, of course, but the lake would lose the unique genetic lineage of the fish that have lived there for thousands of years.

 

 

The Future

 

Could chemical herbicide treatments for Eurasian watermilfoil be reducing fish recruitment in other lakes? None of the other lakes that have been receiving chemical treatments have had their fish populations surveyed this intensely. Large scale recruitment problems due to loss of important plant cover could be taking place throughout the region where the invasive plant is now being fought. There is no way to know if this is happening, and frankly, up until now, there has been no reason to find out.  Fisheries experts around the state are only now learning of Matzke’s findings on Lake Ellwood. In the future, they will likely start paying more attention to fish recruitment on lakes treated for Eurasian watermilfoil which would allow the Department of Natural Resources to determine whether this crisis is an isolated instance or a more widespread problem.

 

In the meantime, it’s a race against time for Lake Ellwood’s native fish. The question remains: Will the plants come back in time to save these fish populations?

SLM at Family and Youth Casting Call 2013-1.1

May 30, 2013 – Through its corporate volunteering program, The SOLution, SOLitude Lake Management, an industry leader in lake and pond management, fisheries management and related environmental services for the mid-Atlantic and surrounding states, participated in The Family and Youth Casting Call as volunteers, by stocking fish, and as a platinum sponsor of the event. The event was held May 3 – May 4, 2013 at the Fletcher’s Boat House in Washington, D.C. Over 700 youth attended this year.

In its 7th year, this annual event is geared towards getting kids outdoors, active, “hooked” on fishing, and educated about the importance of natural resources. SOLitude stocked just under 2,000 adult bluegill and largemouth bass, including several huge bass, in the C&O Canal for the children to catch and release.

SOLitude Lake Management also donated 97 total volunteer hours and set up a hands-on shad spawning game to demonstrate the shad’s difficult journey downriver to the open ocean, and then back upriver to lay their eggs. The children pretended to be in a simulated water environment, avoiding challenges and potential predators as they made their way through the obstacle course following the shad’s dangerous path.

“It was a really fun opportunity for our team to share our enthusiasm for water resources with the kids,” said Shannon Junior, Aquatic Ecologist and Regional Manager for SOLitude. “Many of them had never caught a fish before, and it’s an experience that they’ll remember forever.”

The SOLution is a company-wide program that encourages the company and all employees to strive to “create a better world” through volunteerism, community outreach, sustainability and environmental consciousness. SOLitude’s company leadership feels it is important to not only be good stewards of the environment and good corporate citizens, but also to fulfill company core values to “take action and be accountable” and to “protect and respect nature.” To participate or share a non-profit’s goals for consideration in The SOLution, contact Tracy King at tking@solitudelake.com.

Spidery habitats

Fish habitats built by volunteers at Build a Brush workshops.Kaylea M. Hutson

Anglers and others who have a passion for all things Grand Lake will have a chance to learn how to build an artificial fish habitat on Saturday, during a workshop sponsored by Grand River Dam Authority.

The “Build A Brush” hands-on workshop, set for 9 a.m. Saturday, May 11, Wolf Creek Park, is designed to teach people how to build artificial fish habitats made using cement blocks and plastic pipes.

Members of the GRDA staff will be on hand during the event, to teach those gathered how to make the habitats, known as “spider blocks” because of the way the black plastic pipes resemble spider legs.

Jacklyn Jaggars, assistant director of GRDA ecosystems and lake management, said the spider blocks become fish habitats once immersed in the lake, because moss and algae grow on the pipes. Five or six blocks placed together provide cover for even the smallest fish.

Those in attendance will have the opportunity to take home several blocks, and encouraged to place them in their favorite fishing spots, explained Jaggars.

The workshop is set for 9 a.m., Saturday, May 11, at the Wolf Creek Park. The event is free, but Jaggars said reservations are encouraged to ensure they have enough materials. To register, persons may call 918-256-0723.

This is the first of two “Build a Brush” workshops. The second workshop is set for Saturday, June 1, at Cherokee State Park, below the Pensacola Dam in Langley. More habitat articles at fishiding.com

Non-Profit Group Creating Fish Habiat

Non-Profit Group Creating Fish Habiat for the Cape Fear River

A project to help restore declining fish populations is underway along the Cape Fear River.  We’ll explain how crushed granite will be the basis for a new fish habitat. More habitat articles at fishiding.com

Trade practices around the port city of Wilmington over the past century have caused a significant decline in the number of fish in the Cape Fear River.  But thanks to the efforts of a local non-profit, their populations are staging a comeback.  Cape Fear River Watch Riverkeeper Kemp Burdette says there are several reasons why the fish numbers have dropped, but main reason is the construction of three dams on Cape Fear River in the early 1900’s.  The dams were originally built to facilitate trade and commerce along Cape Fear River between Wilmington to Fayetteville.

“Barges would approach the dam and would move into a lock chamber adjacent to the dam and that lock chamber would be flooded or drained depending on which way they were going and those boats would continue upstream.”

While the dams were beneficial for navigating barges and vessels, they prevented migrating fish species like striped bass, American shad, as well as the endangered Atlantic sturgeon and short nose sturgeon from swimming upstream to spawn during the spring.

“The American shad for instance, we are basically at 10 percent of what historic levels were. Nine out of every ten fish that used to be in the Cape Fear River are not there now. But none of these fish, none of these migratory species are even approaching the population numbers that would be considered healthy.  So, they all need help.”

To help restore the natural migration of fish in the Cape Fear River, the Army Corps of Engineers constructed of a fish ladder at Lock and Dam one in Reigelwood last year. It’s the first one of its kind on the east coast of the United States.  Fish climb the stair-step like structure made from carefully placed rocks by leaping out of the water, level by level, until they’re over the twelve foot high dam.  It’s the first migrating season since the fish ladder has been in place, and Burdette says it’s being used.

“The Division of Marine Fisheries has tagged fish with sonic tags then they’ve gone out and collected this data and these studies show these fish are using these fish passages, striped bass and shad are both using these fish passages, they’re both moving upstream unassisted for basically the first time in one hundred years so it’s really a significant breakthrough for the Cape Fear River and the migratory fish in the Cape Fear River.”

Now two more Cape Fear fish ladders are in the planning phase. Two grant applications were recently submitted to the National and Oceanic and Atmospheric Administration to fund the design, construct, and monitor rock ramp fish ladders at the other dams on the Cape Fear River.

While one project focuses on helping migrating fish travel upstream, another project in the works will help restore breeding habitat.  Coastal Scientist Dawn York explains the project.

“Basically, the premise is to design a site where we can place about 1,000 tons of rocks down in an area that will help enhance spawning habitat for American shad.”

York is with Dial Cordy and Associates, an independent environmental consulting firm working with the Cape Fear River Watch as well as state and federal agencies on creating the fish habitat. She says the rocks will be placed at a half-acre area downstream of lock and dam 2.  An exact location for the habitat hasn’t been decided.  Crushed granite, ranging in size from 2 to 10 inches, will be set at the bottom of the Cape Fear River providing a safe place for striped bass, herring, and sturgeon to lay their eggs.  York says a dredging company in Wilmington will help facilitate the construction.

“They’ll travel up river it’ll take about 4-5 days to mobilize to lock and dam 2. They’ll use their excavator and smaller equipment to get the material onto a barge and they can handle about 90 tons per day. So we’re anticipating the construction of the restoration of habitat will take about 4 to 6 weeks.”

York says they want the first and last ton of granite material to be hand tossed into the water by volunteers.

“The rest of it would then be handled by the barge and mechanical means, basically an arm that will come down and grab large handfuls of material and place it into the river.  It’s going to be sort of spaced out over a half acre, so it’s sort of a flat area.

Construction should take place between December of this year and February 2014. The project can’t begin sooner because of a moratorium banning the placement of material in the water due to fish migration.  Cape Fear River Watch Riverkeeper Kemp Burdette says the next several months will be spent finding the best location for the new fish habitat.

“It’s not nearly as simple as taking rock out there and dumping it off.  What we’re really going to do is side scan assessments of the riverbed and what we’re trying to do there is understand what the riverbed looks like and what the substrate looks like and identify the best places to put the granite.”

Even with the project wrapping up in early 2014, Burdette says their work repopulating the waters of Cape Fear River with migrating fish species is far from over.

“The project at lock and dam number one was a huge first step, but it’s not the last step.  We still have two more dams we need to have fish passage around because we really need these fish to get up into the fall line, that’s the area where they want to spawn, that’s the area where spawning would be most successful and so that’s where we need to go.”

Even though the construction isn’t underway, the project is already receiving national attention.  The National Fish Habitat Partnership has listed the Cape Fear River as one of the “10 Waters to Watch,” for its locally driven conservation areas and ongoing efforts.

Fishing is permitted at all three lock and dam sites, however, there is a moratorium on keeping striped bass.  It is illegal to keep sturgeon because they are an endangered species.  A dock was recently installed at lock and dam number one downstream from the dam structure and Burdette says it’s a popular fishing site for shad.   If you’d like to see a picture of the fish ladder in place at lock and dam one in Reigelwood, go to publicradioeast.org.

Fisheries habitat plan aims at ensuring great fishing for the long term

NEWS RELEASE — St. Paul, MN – Dirk Peterson won’t tell anglers where to catch a big fish, but he can tell them what’s needed to make sure there are big fish to catch when they get there.

More and more these days, he’s boiling it down to three words: good fish habitat. More habitat articles at fishiding.com

Peterson is in charge of the Minnesota Department of Natural Resources’ (DNR) fisheries section, which has just launched a new fisheries habitat plan. It outlines a strategic road map for making sure the state’s 10,000 lakes and hundreds of rivers and streams continue to provide the healthy aquatic habitat underpinning great fishing.

Pete Jacobson, a DNR fisheries research supervisor and one of the plan’s authors, makes it sound pretty simple. “The reason we have good fishing in Minnesota is because we have many lakes and streams with good water quality and habitat,” he said. “Healthy fish habitat is critical.”

But assuring the future of healthy aquatic habitat is anything but simple, because clean water depends on all that happens across a watershed, the hundreds or thousands of acres that drain into any particular lake or stream.

“When you lift a fish out of the water, that fish is a reflection of all that happens on the land,” Peterson said. “If we want to maintain great fishing, we need to focus more effort at the landscape and watershed scale.”

Peterson compares fisheries management to a three-legged stool: one leg is stocking fish, one leg is regulations that help control harvest, and one leg is habitat. Historically, the first two legs have been a little longer and more robust than the last one. The new plan aims to rectify that imbalance by directing staff and other resources to habitat protection and restoration.

While past fisheries habitat projects focused more on near-shore efforts such as protecting aquatic vegetation and stream channel improvements, the new approach seeks to move away from the water’s edge to encompass entire watersheds.

Because the DNR has little authority over land use – a chief determinant of water quality – working at the watershed level will rely more extensively on collaboration and coordination with other DNR divisions, local government, landowners, and other state and federal agencies.

Now there’s collaboration with DNR’s Forestry Division and local soil and water conservation districts to protect the watersheds of lakes with healthy populations of tullibee, a coldwater species sensitive to water quality, which provides important forage for game fish.

In the metro region, watershed scale collaborations with local government and other agencies have helped protect several trout streams, including Dakota County’s Vermillion River, a trophy brown trout stream just a half hour from downtown St. Paul.

While DNR fisheries has undertaken a few larger scale habitat projects before, they tended to be few and far between because there was little funding for big-picture, long-term approaches. The passage in 2008 of a state constitutional amendment dedicating a portion of a sales tax hike to the outdoors and to clean water has changed that. Much of the new habitat plan, available on the DNR website athttp://www.files.dnr.state.mn.us/fish_wildlife/fisheries/habitat/2013_fishhabitatplan.pdf, is aimed at better coordination and focus of funding sources to achieve the most bang for the buck.

An increase in fishing license fees – approved by the Minnesota Legislature last year – also is helping to put more focus on fisheries habitat work.

“We’ve always talked about habitat, but there rarely was adequate funding to really attack it at the appropriate scale,” said Jacobson, the fisheries researcher. “The constitutional amendment changes that, and we need to take advantage of it. The amendment is a mandate from the people for us to take fish habitat conservation seriously. This plan helps us do that.”By Site Editor
