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.
Herdwick sheep in an extensive hill farming system, Lake District, England.The sheep are free to climb to the unfenced upland area. Extensive farming or extensive agriculture (as opposed to intensive farming) is an agricultural production system that uses small inputs of labour, fertilizers, and capital, relative to the land area being farmed.
Aquaculture is the most rapidly expanding food industry in the world [7] as a result of declining wild fisheries stocks and profitable business. [2] In 2008, aquaculture provided 45.7% of the fish produced globally for human consumption; increasing at a mean rate of 6.6% a year since 1970.
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.
According to the FAO, "...a fishery is an activity leading to harvesting of fish.It may involve capture of wild fish or raising of fish through aquaculture." It is typically defined in terms of the "people involved, species or type of fish, area of water or seabed, method of fishing, class of boats, purpose of the activities or a combination of the foregoing features".
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.
Intensive animal farming, industrial livestock production, and macro-farms, [1] also known as factory farming, [2] is a type of intensive agriculture, specifically an approach to mass animal husbandry designed to maximize production while minimizing costs. [3]
The Fishmonger's Shop, Bartolomeo Passerotti, 1580s Fish on a trawler's deck. People interact with fish in multiple ways, whether practically, in folklore and religion, or in art. They have economic importance in the fishing industry and fish farming; these industries provide some people with an income, and the general population with fish as food.
