Fisheries and aquaculture are, directly or indirectly, a source of livelihood for over 500 million people, mostly in developing countries. [9] Social sustainability can conflict with biodiversity. A fishery is socially sustainable if the fishery ecosystem maintains the ability to deliver products the society can use.
Aquaculture involves cultivating freshwater, brackish water, and saltwater populations under controlled or semi-natural conditions and can be contrasted with commercial fishing, which is the harvesting of wild fish. [2] Aquaculture is also a practice used for restoring and rehabilitating marine and freshwater ecosystems.
The NOAA fisheries service has started using aquaculture to produce sustainable seafood. Aquaculture is fish or shellfish farming. [21] The aquaculture fisheries hatch and raise the fish until market size. [21] By using aquaculture the wild fish will be able to repopulate without the threat of overfishing. The aquaculture fish have a variety of ...

Aquaponics is a food production system that couples aquaculture (raising aquatic animals such as fish, crayfish, snails or prawns in tanks) with hydroponics (cultivating plants in water) whereby the nutrient-rich aquaculture water is fed to hydroponically grown plants.
Investment in sustainable aquaculture [54] can buffer water use in agriculture while producing food and diversifying economic activities. Algal biofuels also show potential as algae can produce 15-300 times more oil per acre than conventional crops, such as rapeseed, soybeans, or jatropha and marine algae do not require scarce freshwater.
Saltwater aquaponics (also known as marine aquaponics) is a combination of plant cultivation and fish rearing (also called aquaculture), systems with similarities to standard aquaponics, except that it uses saltwater instead of the more commonly used freshwater. In some instances, this may be diluted saltwater.
Examples of this include the destruction of fauna and flora on the seabed by bottom trawlers fishing in sensitive marine areas, the deforestation of mangrove forests for fish farms and the transfer of diseases and pharmaceutical residues into wild waters by unsustainable aquaculture operations.
