Salmon and shrimp make up most of the rest, but advances in technology and management techniques are making more species available to the American public. Aquaculture also supports commercial and recreational fisheries. Aquaculture is also a tool to restore habitats and species. Hatchery stock is used to rebuild oyster reefs, grow wild fish populations, and rebuild threatened and endangered abalone and corals. A compelling case can also be made for growing more seafood in the United States.

While the worldwide amount of wild-caught seafood has stayed the same year to year, the amount raised through aquaculture has risen dramatically. The United States is a minor aquaculture producer, ranked 17th in on a global scale—but it is the leading global importer of fish and fishery products. Driven by imports, the U.

West Coast.Scott Lindell, Research Specialist, addresses the challenges of feeding the world's population by By all accounts, marine aquaculture is one of the best and most sustainable ways to meet that challenge. Aquaculture is the farming of aquatic animals or plants principally for food. It includes the breeding, rearing, and harvesting of fish, mollusks, crustaceans, and plants in fresh and saltwater environments.

The practice originated in China about 4, years ago, and global production continues to be dominated by China and other Asian countries. Aquaculture is used to produce food by some of the poorest communities around the globe as well as by major corporations.

Globally, aquaculture already supplies more than half of all seafood consumed by humans, a proportion that continues to rise as the world population grows. According to the Food and Agricultural Organization FAO3 million tons of food were produced by aquaculture in the s, a figure that rose steadily to over 80 million tons in Meanwhile, annual global fishing harvests have been flat for 40 years and are not expected to increase in the future see figure, below.

More than aquatic species are farmed. The top fish species include carp, catfish, salmon, and tilapia; commonly farmed shellfish include shrimp, oysters, clams, mussels, and scallops.

Aquaculture also includes the production of fish for the aquarium trade and algae for the pharmaceutical, biotechnology e. Other leaders include Indonesia, India, and Vietnam. Some of the challenges in the U. Aquaculture is a major source of seafood for the U. Many different aquaculture production systems are in use around the world, each with its own pros and cons. Commonly used include ocean net pens, coastal or inland ponds, fully-enclosed systems on land, and systems suspended by ropes, floats, and anchors in open water.

Marine fish such as salmon are often farmed using ocean net pen systems, which allow for the free exchange of water between the farm and the environment.

In its brief year history, marine fish farming encountered many early challenges from untested management practices and had to learn to cope with diseases, waste deposition, escapes, and interactions with other marine life. Most of those challenges have been successfully addressed by major investments in technology and modern management methods such as routine fallowing of farm sites, vaccinations, advances in nutrition and feed delivery, and better farm engineering and monitoring.

Tilapia and shrimp are often farmed in semi- or fully-enclosed ponds where water exchange is controlled. Normally, the waste discharged with effluent water is biologically treated before it enters the natural environment. If not properly managed, these pond-based systems have the potential to degrade downstream environments such as sensitive wetlands and mangroves. More capital and energy-intensive systems that pose fewer risks to the surrounding environment include fully enclosed and recirculating systems that also treat and discharge relatively small volumes of the water to the environment.

Fish farmed in this manner include salmon, Arctic char, tilapia, and sea bass. Shellfish eat plankton that they filter out of the water, and seaweeds absorb dissolved nutrients—neither needs additional inputs. These systems consist of tensioned and submerged horizontal ropes held in place by anchors and buoys from which shellfish or seaweeds are suspended; sometimes shellfish are supported inside trays or mesh bags.

Historically, freshwater aquaculture particularly carp and catfish has been and continues to be responsible for the majority of global production. Marine aquaculture is playing an increasingly important role for the planet as a food and potential energy source, especially as arable land and freshwater become increasingly scarce.

Not only is aquaculture the most rapidly expanding sector of food production, it is one of the most resource-efficient ways to produce proteinaccording to NOAA. Marine aquaculture has already helped improve nutrition and food security in many parts of the world where wild fish stocks have collapsed.

Looking ahead, it could be the answer to a major food sustainability challenge. To preserve the natural terrestrial environment we have left, most new food supplies must come from the ocean.

Shellfish and seaweed aquaculture also provide valuable services to marine ecosystems and the planet. Shellfish and seaweeds absorb carbon dioxide rather than producing it like land-based livestock. These forms of low-impact food production mitigate climate change while sustainably feeding future generations.

For these reasons, environmental organizations such as the World Wildlife Fund and The Nature Conservancy actively champion shellfish and seaweed farming. Researchers have turned to biofuels—fuels generated by biological processes—as a potentially renewable source of energy that can in principle be carbon-neutral. Biofuels from land-based sources such as corn and sugarcane require arable land, fertilizers from fossil fuels, and scarce fresh water, whereas biofuels from marine algae and seaweeds require only sunlight and abundant seawater.

Given the potential for aquaculture to meet two critical human needs—food and energy—WHOI scientists are working with resource managers and companies to find safe ways to scale up production in the U.Changing Futures and Achieving Excellence Together. The Aquaculture Center serves a community of diverse students with a broad range of social, economic, cultural and ethnic backgrounds who bring to the school a variety of skills, talents and learning styles.

As the demand for seafood has increased, technology has made it possible to grow food in coastal marine waters and the open ocean. Aquaculture is a method used to produce food and other commercial products, restore habitat and replenish wild stocks, and rebuild populations of threatened and endangered species.

There are two main types of aquaculture—marine and freshwater. NOAA efforts primarily focus on marine aquaculture, which refers to farming species that live in the ocean and estuaries.

In the United States, marine aquaculture produces numerous species including oysters, clams, mussels, shrimp, seaweeds, and fish such as salmon, black sea bass, sablefish, yellowtail, and pompano.

NOAA is committed to supporting an aquaculture industry that is economically, environmentally and socially sustainable. NOAA experts and partners work to understand the environmental effects of aquaculture in different settings and provide best management practices to help reduce the risk of negative impacts. Aquaculture is breeding, raising, and harvesting fish, shellfish, and aquatic plants.The family also raises fish in the pond and, in the dry season, rice fertilized by fish waste—a polyculture that has tripled output with little environmental downside.

Fat, white tilapia the size of dinner plates boil to the surface. Unlike Jesus, however, Martin does not give his fish away. Each day he sells 12, pounds of live tilapia to Asian markets from Washington, D.

But industrial-scale fish farms are popping up everywhere these days. Aquaculture has expanded about fold since In its global output, from silvery salmon to homely sea cucumbers only a Chinese cook could love, reached more than 70 million tons—exceeding beef production clearly for the first time and amounting to nearly half of all fish and shellfish consumed on Earth.

With the global catch of wild fish stagnant, experts say virtually all of that new seafood will have to be farmed. So they want it to be right from the start. Tilapia pens in Laguna de Bay, the largest lake in the Philippines, are choked by an algal bloom they helped create.

The overstocked lake produces large numbers of farmed fish, but excess nutrients trigger blooms that use up oxygen—and kill fish. Aquacultural pollution—a putrid cocktail of nitrogen, phosphorus, and dead fish—is now a widespread hazard in Asia, where 90 percent of farmed fish are located. To keep fish alive in densely stocked pens, some Asian farmers resort to antibiotics and pesticides that are banned for use in the United States, Europe, and Japan. The U.

In and the FDA discovered numerous banned substances, including known or suspected carcinogens, in aquaculture shipments from Asia. Nor have fish farms in other parts of the globe been free of problems. The modern salmon industry, which over the past three decades has plunked densely packed net pens full of Atlantic salmon into pristine fjords from Norway to Patagonia, has been plagued by parasites, pollution, and disease. A disease outbreak in virtually wiped out the shrimp industry in Mozambique.
