The largest deep water open ocean farm in the world is raising cobia 12 km off the northern coast of Panama in highly exposed sites. [ 10 ] [ 11 ] There has been considerable discussion as to how mariculture of seaweeds can be conducted in the open ocean as a means to regenerate decimated fish populations by providing both habitat and the basis ...
The global annual production of freshwater prawns (excluding crayfish and crabs) in 2007 was about 460,000 tonnes, exceeding 1.86 billion dollars. [46] Additionally, China produced about 370,000 tonnes of Chinese river crab. [47] In addition astaciculture is the freshwater farming of crayfish (mostly in the US, Australia, and Europe). [48]
Crustaceans - brine, shrimp, prawns - these can be included as part of a wastewater treatment program as some have the capacity to quickly clean water; Molluscs - mussels; Algae - both unicellular and "seaweeds" can be used to extract a range of high-value products, including pharmaceutical chemicals.
The basic requirement is to have a ditch or pond that retains water, possibly with an above-ground irrigation system (many irrigation systems use buried pipes with headers). [31] Using this method, water allotments can be stored in ponds or ditches, usually lined with bentonite clay. In small systems, the fish are often fed commercial fish food ...
