Fish farming or pisciculture involves commercial breeding of fish, most often for food, in fish tanks or artificial enclosures such as fish ponds. It is a particular type of aquaculture , which is the controlled cultivation and harvesting of aquatic animals such as fish, crustaceans , molluscs and so on, in natural or pseudo-natural environments.
The aquaculture or farming of piscivorous fish, like salmon, does not help the problem because they need to eat products from other fish, such as fish meal and fish oil. Studies have shown that salmon farming has major negative impacts on wild salmon, as well as the forage fish that need to be caught to feed them.
The fish farm was run by Cooke Aquaculture Pacific, LLC. [1] According to the Washington State Department of Natural Resources, inadequate cleaning was likely the primary cause for the pen break; the nets were supporting more than six times their own weight in biofouling. [2] Coastal tribes were hired to fish the escaped salmon.
Mariculture, sometimes called marine farming or marine aquaculture, [1] is a branch of aquaculture involving the cultivation of marine organisms for food and other animal products, in seawater. Subsets of it include ( offshore mariculture ), fish farms built on littoral waters ( inshore mariculture ), or in artificial tanks , ponds or raceways ...
Organic aquaculture is a holistic method for farming fish and other marine species in line with organic principles. [1] The ideals of this practice established sustainable marine environments with consideration for naturally occurring ecosystems, use of pesticides, and the treatment of aquatic life. [2]
Also, fish farming in the Mediterranean is a net fish consumer. Large amounts of animal feed are needed to feed a high trophic fish like the bluefin tuna. This feed consists of fishmeal processed from forage fishes like sardines and anchovies that humans would otherwise consume directly. In addition to ecological issues, this raises ethical issues.
Raising fish in cages in a lake in a relatively undeveloped environment. Urban aquaculture employs water-based systems, the most common, which mostly use cages and pens; land-based systems, which make use of ponds, tanks and raceways; recirculating systems are usually high control enclosed systems, [clarification needed] whereas irrigation is used for livestock fish.
Aquaculture (fish farming) is used for all Atlantic cod production, so that the environment and natural (wild) fish species are essentially unaffected. Fish are sold without further processing, so little to none of the animal is wasted. The only environmental concern from Atlantic cod is excess nutrients produced in their feces.
