The new, second edition of the National Fish Habitat Action Plan advances science-based conservation mission and incorporates new objectives focused on locally driven efforts to reverse deteriorating fish habitats.

National Fish Habitat Action Plan, Second Edition

The revised Action Plan is built on the success and experience of our Partners.

Washington, DC (PRWEB) August 29, 2012

The National Fish Habitat Board today released the second edition of the National Fish Habitat Action Plan (Action Plan), setting forth a mission-critical approach to conserving the nation’s aquatic resources for the future. The original National Fish Habitat Action Plan, created in 2006, carried a great vision forward to protect, restore and enhance aquatic habitats through partnerships. While the original Plan met its objectives set forth in 2010, the mission and goals of the plan remain the same and are the foundation of the second edition of the Plan for 2012 and beyond.

The second edition of the National Fish Habitat Action Plan is built on the foundation of advancing the conservation practices of the individual National Fish Habitat Partnerships, the working units of the National Fish Habitat Partnership. The five new objectives in the Plan include:

• • Achieve measurable habitat conservation results through strategic actions of Fish Habitat Partnerships that improve ecological condition, restore natural processes, or prevent the decline of intact and healthy systems leading to better fish habitat conditions and increased fishing opportunities.

• • Establish a consensus set of national conservation strategies as a framework to guide future actions and investment by the Fish Habitat Partnerships by 2013.

• • Broaden the community of support for fish habitat conservation by increasing fishing opportunities, fostering the participation of local communities – especially young people – in conservation activities, and raising public awareness of the role healthy fish habitats play in the quality of life and economic well-being of local communities.

• • Fill gaps in the National Fish Habitat Assessment and its associated database to empower strategic conservation action supported by broadly available scientific information, and integrate socio-economic data in the analysis to improve people’s lives in a manner consistent with fish habitat conservation goals.

• Communicate the conservation outcomes produced collectively by Fish Habitat Partnerships as well as new opportunities and voluntary approaches for conserving fish habitat to the public and conservation partners.

The second edition of the Action Plan details how the new objectives will be implemented. The Plan also highlights conservation “Partnership in Action” stories from Fish Habitat Partnerships to provide insight into their work on the ground. Other sections explain the functions of the National Fish Habitat Board and Partnerships and the critical role of science and data and effective communications to guide activities. Interesting facts and figures related to the National Fish Habitat Partnership, recreational and commercial fishing fill out the rest of the Plan.

“The revised Action Plan is built on the success and experiences of our Partners,” said Kelly Hepler, Chairman of the National Fish Habitat Board and Assistant Commissioner, Alaska Department of Fish and Game. “Creating and maintaining these Partnerships is the foundation of the Action Plan and will be the primary focus as we address conservation needs for our nation’s waterways now and into the future.”

The National Fish Habitat Board, Fish Habitat Partnerships, federal and state natural resource agencies, conservation organizations and the National Fish Habitat Partner Coalition participated in the selection process of the revised Plan objectives. The release of the revised Action Plan coincides with the launch of the updated National Fish Habitat Partnership website at http://www.fishhabitat.org.

About the National Fish Habitat Partnership
The National Fish Habitat Partnership (http://www.fishhabitat.org) works to conserve fish habitat nationwide—leveraging federal, state and private funding sources to achieve the greatest impact on fish populations through priority conservation projects. The national partnership implements the National Fish Habitat Action Plan and supports 18 regional grassroots partner organizations.

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

ES&E Magaqzine’s May/June 2012 issue

An enhanced floating treatment wetland (FTW) that incorporates air diffuser technology is under evaluation in an ongoing study at Floating Island International in Montana. The latest-generation system lifts and circulates water through floating streambeds within the FTW. This combination of FTW and improved water circulation/aeration is part of a product range called BioHaven®. The primary objective of the study is to determine whether biofilm-based microbes can provide nutrient removal, while increasing fish productivity.

This system, which is a new type of
constructed wetland, has been evaluated
for treatment of agricultural effluent and
municipal wastewater. Cost-effective treatment options for end users with limited
funding will be its greatest benefit. It can
provide treatment of agricultural-impacted
waters, municipal wastewater, storm water
and polishing of tertiary waste water, along with lake restoration.

Fisheries managers will be especially interested in the productivity potential afforded by a biological system, which can reduce algae and grow more (and bigger) fish. 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.

Wetland areas have been reduced worldwide, while nutrient loading has increased
with growing human populations. Mass-production agriculture, as practiced in many developed nations, can contribute to hyper-eutrophication in water bodies that were previously low in nutrient concentrations. In fresh water, partly as a result of normal seasonal stratification, nutrient loading can deplete oxygen levels within the livable temperature zone for fish species.

Over the last 11 years, Floating Island
International (FII) has developed the Bio-
Haven FTW technology, which mimics
the ability of natural peat-based wetlands
to purify water. The Leviathan™ extrapolates
this technology by maximizing surface area and circulation, which are key components of wetland effectiveness. The islands are also designed to provide
optimal perennial plant habitat.

System background:
Dissolved oxygen and temperature measurements taken on Fish Fry Lake,
FII’s 6.5-acre research lake in 2008/2009 indicated that stratified water near the
surface was too warm to sustain a trout fishery. While temperatures below the
stratified warm water layer were sufficiently cool for trout, that zone contained
low dissolved oxygen (DO) levels. During late summer, no strata of water could
consistently provide the cold-water, high- DO environment demanded by fish, such
as rainbow, brown and Yellowstone cutthroat trout.
Groundwater containing variable nutrient concentrations enters the lake at an estimated average rate of 18 m3/hr. Surface water also flows into the lake with variable nutrient concentrations and flow rates. Evaporative loss and outflow are balanced to maintain the lake level, which is approximately 9 m deep.

As the lake was filled several years
ago, a series of BioHaven floating islands
covering 5,200 square feet (480 m2) of
lake area and providing over 9.3 ha of saturated surface area was installed. Several
islands were positioned next to the inflow
to maximize exposure to the highest nutrient concentrations.

These islands were designed to maximize production of biofilm (organisms attached to underwater surfaces), and to move nutrients into and through the food web.
After addition of the last 232-m2 FTW, floating islands now cover approximately 715 m2, or 2.7% of the lake’s surface area. Active treatment system with floating streambed Leviathan is an enhanced form of constructed wetland, and is FII’s latest effort to move excess nutrients into the food chain or harvest them. It integrates high volume, low-pressure circulation with matrix surface area constructed of postconsumer (recycled) polymer fibers, for maximum wetland performance.

Air-driven directional diffusers circulate up to 2,300 m3/hr, pushing it through the Bio-
Haven matrix and plant roots. The system’s floating streambed contributes to aeration and nutrient uptake.

The FPZ-brand air diffusers require 3 hp (2.2 kW) to operate, typically with 230V
single-phase power. Leviathan is designed to provide the  complete “wetland effect,” including aerobic, anaerobic and anoxic microbial nutrient conversion. This allows it to treat large, nutrient-rich stratified bodies of water, including “dead zones,” in both freshwater and marine settings. Removal of ammonia, nitrate, phosphate and soluble organic carbon has been demonstrated.

The system can move nutrients from
any depth into and through the islands’
biologically active substrate. In the
process, these nutrients are digested by
beneficial microbes and form periphyton
(attached plant and animal organisms
embedded in a polysaccharide matrix,
similar to biofilm), which is the base of
the freshwater food chain. As these excess nutrients transition into the food chain via biofilm/periphyton, both water quality and fish growth rates can be dramatically improved.
Leviathan can de-stratify water bodies, resulting in greatly expanded habitable zones for targeted fish species. As part of this process, high DO levels can be achieved and maintained, and water temperatures homogenized.

Results:
A 232-m2 Leviathan system, incorporating floating streambeds and grid-powered water circulation, was installed in the lake in April 2009. This system circulated up to 770 m3/hr through the stream channels within the island. Each cubic meter of Leviathan’s matrix, averaging 0.64 m in thickness, provided 820 square meters of surface area.

After 17 months of operation, water clarity had improved from a low of 0.36 m of visibility to as much as 3.3 m. Clarity is now at 5.8 m. Simultaneously, the
water temperature gradient was reduced, creating a larger zone of “livable” water for fish. Two age classes of Yellowstone cutthroat trout were introduced 13 and 14 months into the test. Through the summer of 2010, a favorable temperature/dissolved oxygen strata, ranging from the water surface down to a depth of at least 3.7 m, was maintained as potential cutthroat trout habitat.

One-year-old and two-year-old black crappie were also introduced two months
into the test, and naturally-occurring northern yellow perch were present in the
lake when it was filled. All three species have flourished.

The new aeration scheme in the lake improves water quality by incorporating
dissolved phosphorus and nitrogen into the aquatic food web, in the form of periphyton,
while limiting the growth of deleterious algae. Total phosphate concentrations
are reduced from about 0.04 mg/L to 0.02 mg/L, while nitrate-nitrogen
concentrations decrease from about 0.6 mg/L to 0.01 mg/L.
Fish Fry Lake is relatively unique in that it supports fish accustomed to cold
water (Yellowstone cutthroat trout), temperate water (perch) and warm water
(crappie). Montana officials have made two unsuccessful attempts at sustaining
cutthroat populations in an adjacent stretch of the Yellowstone River.
Fish catch rates and growth rates are now being monitored at the lake. Initial
data show that experienced fishermen catch an average of one perch every two
minutes. Visual observations from diving and an underwater viewing station indicate
that perch approaching or exceeding the Montana state record of 1.0 kg now
inhabit the lake.
The perch harvest at Fish Fry Lake averaged 12 kg of fish per week from May-
November 2011. With a phosphorus content of 0.9% in perch, phosphorus removal
from the lake via fishing averaged 0.10 kg/wk, or 84% of the estimated
phosphorus input to the lake.
In summary, Fish Fry Lake was poised to become another eutrophic waterway, until a new form of applied stewardship was introduced, which reversed the process.

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!

In a recent article published in Pond Boss (www.pondboss.com) Bruce explores the concept of turning Phosphorus into fish to improve water quality. Here’s a quick link to the article:http://www.floatingislandinternational.com/wp-content/plugins/fii/news/37.pdf

Conservation Summit Emphasizes Fisheries Management  

“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. This something that I promised to do when I came back to B.A.S.S. last year,” said National Conservation Director Noreen Clough, who added that she is “very excited to bring back an historic event unique to B.A.S.S. Conservation.”
Federation Nation conservation directors, state fisheries managers, academics, “and other notables in fisheries and aquatic resource conservation” will attend.
An inaugural Fisheries Management Workshop on Saturday will be one of the summit’s highlights, as will a keynote address by Jim Martin, Berkley Conservation Institute director, at Saturday night’s awards banquet. Martin also will give closing comments on Sunday.
“Jim is a great partner with B.A.S.S. and an awesome motivational speaker in the conservation world,” Clough said.
Saturday’s workshop will feature Dr. Mike Allen from the University of Florida, Dr. David Philipp from the University of Illinois, and Gene Gilliland from the Oklahoma Department of Wildlife Conservation, three of the nation’s foremost experts on fisheries management.
“We’ve been able to bring together fisheries scientists from universities and states around the country to share with us the latest in black bass management,” said Clough.
Among other topics, Philipp will provide “the Northern perspective” on fishing for nesting bass, and Allen will offer the Southern perspective. Gilliland will talk about tournament mortality issues, catch-and-release impacts on growth, and advances in techniques and tools, including the Alabama Rig.
Conservation directors also will learn about trends in fish culture and stocking, illegal stocking, and spatial patterns in bass habitat use and angling. They then will move to breakout sessions to discuss management and science/outreach needs for bass fisheries.
Following a welcome from B.A.S.S. co-owner Jim Copeland, Friday’s agenda will feature mentoring sessions, legislative updates, and news from the conservation directors. The latter will include the latest on ReBaits, the popular program initiated by Florida’s Eamon Bolten to encourage anglers to recycle or properly dispose of their used plastic baits.
Gordon Robertson, vice-president of the American Sportfishing Association, and Chris Horton, mid-states coordinator for the Assembly of State Caucuses, will discuss federal and state legislation related to fisheries, as well as offer insights about working with legislators and getting involved politically.
Allen and Dr. Mike Netherland from the U.S. Army Corps of Engineers will discuss aquatic vegetation management and related issues, including the likelihood that herbicide application changes the behavior of fish.

Sunday’s half-day program will offer insights on how to partner with state agencies from a panel of fisheries chief, a look at the process behind fisheries management from Gilliland, and federal updates on the 75th anniversary of the Sport Fish Restoration Program (Wallop-Breaux) and the U.S. Fish and Wildlife Service fisheries program.
