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.
An extended cost–benefit analysis of the total economic value of shrimp aquaculture built on mangrove ecosystems found that the external costs were much higher than the external benefits. [127] Over four decades, 269,000 hectares (660,000 acres) of Indonesian mangroves have been converted to shrimp farms.
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.
Whether octopus farming is profitable depends in large part on how much it costs to maintain a steady supply of crustaceans. [25] Economic profitability can be maximized without significantly compromising biological productivity by incorporating a mix of fish and crustacean-based feed strategies.
World capture fisheries and aquaculture production by species group [1]. The global commercial production for human use of fish and other aquatic organisms occurs in two ways: they are either captured wild by commercial fishing or they are cultivated and harvested using aquacultural and farming techniques.
Sustainable fish farming practices do not use dangerous chemicals, hormones, or antibiotics on their fish, which benefits the surrounding marine environment, and the human consumers themselves. In addition to this, sustainable fish farming is able to control what their fish eat: farmers will take care to keep the fish's diet healthy and balanced.
In 2018, Canada's fishing industry was worth $36.1 billion in fish and seafood products and employed approximately 300,000 people. [1] Aquaculture, which is the farming of fish, shellfish, and aquatic plants in fresh or salt water, is the fastest growing food production activity in the world and a growing sector in Canada.
In 2007, 6.4 million tonnes of fish were caught by EU countries. [6] The EU fleet has 97,000 vessels of varying sizes. Fish farming produced a further 1 million tonnes of fish and shellfish and employed another 85,000 people. The shortfall between fish catches and demand varies, but there is an EU trade deficit in processed fish products of € ...
