It has been called "the central problem of fish population dynamics" [14] and “the major problem in fisheries science". [15] Fish produce huge volumes of larvae, but the volumes are very variable and mortality is high. This makes good predictions difficult. [16] According to Daniel Pauly, [15] [17] the definitive study was made in 1999 by ...
A number of countries have created their own national standards and certifying bodies for organic aquaculture. While there is not simply one international organic aquaculture standardization process, one of the largest certification organizations is the Global Trust, [9] which delivers assessments and certifications to match the highest quality organic aquaculture standards.
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 € ...
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.
Spreading of pathogens between fish stocks is a major issue in disease control. [27] Static offshore cages may help minimize direct spreading, as there may be greater distances between aquaculture production areas. However, development of roaming cage technology could bring about new issues with disease transfer and spread.
Farming (including livestock rearing, dairy products, cereals, potatoes), is a key contributor to the Economy of Ireland. In 2005, Ireland exported approximately €7.3 billion worth of agri-food and drink (about 8.6% of its exports), mainly as cattle, beef, and dairy products, and mainly to the United Kingdom (including Northern Ireland).

Agriculture in Ireland is a major component of the modern economy of the Republic of Ireland. [21] A major livestock producer, Ireland has very limited horticultural and grain production on account of its topography and climate. Ireland manufactures many derivatives and value-added products from its livestock base. However, much of its beef and ...
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.
