A freshwater prawn farm is an aquaculture business designed to raise and produce freshwater prawns or shrimp 1 for human consumption. Freshwater prawn farming shares many characteristics with, and many of the same problems as, marine shrimp farming. Unique problems are introduced by the developmental life cycle of the main species (the giant ...
The gate of a traditional shrimp farm in Kerala, India which uses the tide to harvest shrimp. Shrimp farming is a form of aquaculture that takes place in marine or freshwater environments, producing shrimp or prawns [Note 1] (crustaceans of the groups Caridea or Dendrobranchiata) for human consumption.

Although traditional shrimp farming has been carried out in Asia for centuries, large-scale commercial shrimp farming began in the 1970s, and production grew steeply, particularly to match the market demands of the United States, Japan and Western Europe.
Aquaponics is a food production system that couples aquaculture (raising aquatic animals such as fish, crayfish, snails or prawns in tanks) with hydroponics (cultivating plants in water) whereby the nutrient-rich aquaculture water is fed to hydroponically grown plants.
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]
A raceway farm for freshwater fin fish usually has a dozen or more parallel raceway strips build alongside each other, with each strip consisting of 15 to 20 or more serial sections. [16] The risk of unhygienic conditions increases towards the lower level sections, and can be kept in check by ensuring there are not too many sections and the ...
Fish chosen for extensive aquaculture are very hardy and often do well in high densities. Seaweed, prawns, mussels, carp, tilapia, tuna and salmon are the most prominent forms of extensive aqua cultured seafood. Extensive aquaculture facilities have negative impacts on the environment as well.
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.
