Habitats keep commercial
and recreational fisheries strong
Habitat provides important feeding and breeding grounds forfish. Without the right habitat, fish cant grow or reproduce, and
that means fewerand less healthyfish. U.S. commercial andrecreational saltwater fishing generated more than billioninsales and supported . million jobs in the nations economy in .Fishing has also been a culturally defining activity for generationsof Americans and provides countless opportunities for outdoorrecreation.
If we lose the habitat, we lose the fish
Fish habitat has been declining for decades around the country and therate of loss is increasing. The U.S. lost , acres of coastal wetlandsbetween and , three times higher than to . Withoutaction to protect and restore habitat now, this trend will continue andworsen due to the combined effects of climate change and sea level rise.
So what can we do? Protect and restore habitat
Investments by private groups and government have led to well-testedand effective methods of habitat conservation and restoration. Winwinsolutions with farmers, fishermen, conservationists, and others haveimproved and expanded habitat that fish need throughout their life
cycle, from the upland river to the estuary to the ocean.More, bigger, and healthier fisheries its as simple as that. Habitatconservation and restoration are smart investments not only for ourfisheries but for the communitiesand economiesthat rely on them.

The big challenges that fisheries
face are increasingly habitat
challenges. Without healthy habitat,we cannot sustain the fisheries that
will feed Americans now and intothe future.Eric C. Schwaab, Assistant
Administrator for NOAA Fisheries

Restore fish passage
Fish, such as sturgeon and salmon, spend an important part of their livesupstream. Forage fish,like river herring, are a critical food source for codand other commercially fished species and also depend on the ability to
migrate upstream to reproduce.
Since the th century, rivers have been blocked and diverted to servea developing industrial nation. The mill by the river is long gone, butthe dam or poorly designed culvert remains, still preventing fish fromgetting to habitat where they can feed and reproduce. By making iteasier for fish to travel freely, populations are rebounding to and, insome cases, beyond their historical numbers.
It doesnt take long to see big resultsHerring were completely wiped outabove the Edwards Dam on
the Kennebec River in Maine in . Now the population is at millionthanks to dam removals in and and additionalrestoration. Shad and sturgeon are on the rebound as well.
On Massachusetts Acushnet River, , percent more herringwerecounted four years after two fishways were installed in .
Just two yearsafter the culvert connecting Bride Brook to LongIsland Sound was enlarged in , the herring population morethan tripled from , to ,.

Reef building yields multiple benefits
Over time, shellfish such as oysters and mussels produce three-dimensional structures known as reefs. These reefs are critical not onlybecause they are habitat for shellfish, but also because they provide
shelter and feeding grounds for a host of other species, including fish.Many reefs around the country have been destroyed, so protecting andrestoring them is critical to increasing the populations of shellfish
and fish, along with the wide range of other species that rely on them.
Rebuilding a native populationThe Chesapeake Bay once had a thriving and abundant native
oyster population that has since been decimated. One restorationproject used shell to rebuild the reef structures over a total of acres. Native oysters repopulated these reefs, resulting in a-fold increase in the populationto an astonishing millionoysters within five years.
Restoring oysters, increasing fishIn Mobile Bay, Alabama, constructing an oyster shell reef increasedpopulations of several economically-important species, such as:blue crab by percent; red drum by percent; spotted
seatrout by percent; and flounder by percent.

Protect and restore marsh and seagrass
Marshes and seagrasses provide shelter and food for many importantfish species. Protecting and restoring these habitats are vital toincreasing our nations fish populations.
If you restore it, they will come (back)In San Francisco Bay, , fish from species have returned tothousands of acres of restored salt marsh that were converted forsalt production in the s. These include steelhead trout, Pacificherring, green sturgeon, and Chinook salmon.
In Boston Harbor, eelgrass had been completely wiped out. After
replanting and restoring the eelgrass, these areas showed anincrease in both the diversity and number of species of both fishand their prey. Winter flounder, crab, and lobster were found at thesites, indicating that eelgrass restoration provides new habitat forthese and many other species.
Habitat restoration yieldslong-term benefits to fisheriesIn Delaware Bay, both resident and migratory fish populationsincreased long-term, according to a nine-year study of a formersalt hay farm. The fish were more abundant and grew largerfollowing the marsh restoration.
Forage fish increaseIn Narragansett Bay, Rhode Island, studies showed that a tidal
marsh restoration resulted in increased fish populations,particularly of forage fish. These smaller fish serve as a food sourcefor important commercial and recreational species such as stripedbass, red drum, and blue crab.

Americas anglers are one of thenations most powerful forces
for conserving and restoring
our nations fisheries and waters,
investing more than $1 billion eachyear in fisheries management and
habitat restoration through the
excise tax on fishing equipment and
state fishing license sales.Mike Nussman,

Create sheltered spaces
Many young fish do best when they spend time off channel in thecalm, sheltered waters of floodplains, marshes, and other wetlands.The longer fish stay, the bigger they growand bigger fish are more
likely to survive their trip to the ocean and return to spawn. But manysheltered places no longer exist. Dikes, levees, and similar structuresnow prevent much of the seasonal flooding that sustains thesehabitats.
Creative engineering can help rebuild habitatFish grew six times biggerin off channel ponds created by theYurok Tribe on Terwer Creek in Northern California. Soon after
their completion, they quickly provided crucial habitatfor threesalmon species and other fish. Other studies confirm substantialdifferences in growth rates between fish that get to shelter andthose that dont.
Both fish and farmers can benefit
million in economic benefitsover years are expected toflow from the modernization of diking and drainage structures inthe farmland around Fisher Slough in Washingtons Skagit Delta.This effort has restored critical tidal channel habitat and accessto upstream areas, resulting in population increases in both fishand their prey. In addition to fisheries benefits, farmers will havereduced crop damage from flooding and lower maintenance
costs.
Habitat improvements recover fishand reduce floodingThe Dry Creek tributary of Californias Russian River was historicallychannelized to the point that the flows had become too fast forfish to successfully thrive. Habitat improvements were madein in partnership with a local winery so that calmer areaswithin the creek were created, making it a more suitable areafor fish to reproduce and rear the next generation. As a result of
the project, fish and their offspring are now using the creekand its improved habitat. These actions also reduced floodingand erosion, making it an all-around success story for the fish, thewatershed, and the property owners.
