Unfortunately, when something seems to good to be true, it very often is! Pollution. This density of fish creates problems like disease and pollution.

In some places, stocks have declined or collapsed due to illegal, unreported and unregulated fishing — hitting the coastal communities that rely on seafood for food and income the hardest.

Global demand for seafood has outgrown the production of sustainable wild-caught seafood that our oceans can support. Fish is a high-protein, low-fat, healthy and nutritionally rich food. Aquaculture has the capacity to help meet global demand while reducing the pressure on wild fisheries.

Agricultural production systems, including aquaculture, by their nature, will have impacts on the environment in order to produce food for humans. However, a responsible aquaculture farm has reduced and controlled impacts on the surrounding environment and it efficiently utilizes resource inputs like feed ingredients, water, and energy.

new, production systems in the livelihood or farming system of the intended beneficiaries. All too often, the result was lack of adoption by one of the intended target groups – the rural poor. As a result of the apparent inability to impact the rural poor, donor support for aquaculture development has declined in the past 10 years.

The Food and Agriculture Organization of the United Nations (FAO) contends that the livestock sector alone is responsible for 18% of all greenhouse gas production. Additionally, clearing land for agricultural production is a major contributor to climate change, as the carbon stored in intact forests is released when they are cut or burned.

Total fish production in Nigeria is estimated at about 30 percent of demand, thus scarce foreign exchange is devoted to the importation of large volumes of frozen fish (ThefishSite, 2012). With these advantages, fish production serve as means of employment and sustainable livelihood for fish farmers.

Fish Farming and Aquaculture Environmental Concerns. Although aquaculture provides many benefits, there are several concerns linked to it as well. The impact it presents to the areas it is practiced in needs to be managed to ensure a sustainable operation. Otherwise, aquaculture would suffer the same fate as overfishing wild populations.

From farmed salmon displacing indigenous salmon and other fish to tonnes of aquaculture sludge quietly blanketing and degrading coral reefs and other natural habitats, old-school aquaculture has become a boom-and-bust venture.

Sustainable Seafood. Seafood demand is growing fast, and the global supply of wild-capture fisheries has remained flat for more than 20 years—the ocean has given what it can. As such, the future of sustainable seafood must include both farm-raised and wild-capture seafood. The United States is recognized as a global leader in sustainable seafood—both wild-caught and farmed.
