Fish farming

Fish farming is the principal form of aquaculture, while other methods may fall under mariculture.

It involves raising fish commercially in tanks or enclosures, usually for food.

A facility that releases juvenile fish into the wild for recreational fishing or to supplement a species' natural numbers is generally referred to as a fish hatchery.

Fish species raised by fish farms include salmon, catfish, tilapia, cod and others.

Basically, there are two kinds of aquaculture: extensive aquaculture based on local photosynthetical production and intensive aquaculture, in which the fishes are fed with external food supply.

Australia: From Tuna Hunter to Sushi Saver

A fishing ban is unlikely, so one solution is to breed the fish in underwater cages. But they're not easy to rear in captivity. In Australia, German-born Hagen Stehr is working to mimic natural living conditions of the fish in his onshore farm. The idea is to create an artificial model of the journey to their spawning grounds in order to trick the fish into reproducing.

Recycling Seafood: Oil From Fish Waste

The oils are rich in omega-3 fatty acids, which help prevent cardiovascular problems. The aim is to minimize waste from the fish-processing industry. Other potential leftovers are turned into a powder that is high in protein and may have anti-inflammatory properties.

Reuters (Oct. 8, 2013) New commercial fishing technology from New Zealand may soon put an end to the global problem of bycatch, where non-targeted species are caught up in the nets of commercial fishermen.
