Death occurs below 50 °F (10 °C). Therefore, only the southernmost states are suitable for tilapia production. In the southern region, tilapia can be held in cages from five to 12 months per year, depending on location. [14] About 1.5 million tons of tilapia were consumed in the US in 2005, with 2.5 million tons projected by 2010. [15]
Many cultured fishes (tilapia, carp, catfish, many others) can be raised on a strictly herbivorous diet. Top-level carnivores (most salmonidae species in particular) on the other hand, depend on fish feed, of which a large portion is usually derived from wild-caught fish ( anchovies , menhaden , etc.).
Some Nile tilapia can grow as long as 60 centimetres (2 ft). [12] Other than their temperature sensitivity, tilapia exist in or can adapt to a very wide range of conditions. An extreme example is the Salton Sea, where tilapia introduced when the water was merely brackish now live in salt concentrations so high that other marine fish cannot survive.
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.
Aquaculture in an area can provide for crucial ecological functions for the inhabitants. Shellfish beds or cages can provide habitat structure. This structure can be used as shelter by invertebrates, small fish or crustaceans to potentially increase their abundance and maintain biodiversity. Increased shelter raises stocks of prey fish and ...

Rice and tilapia fish polyculture, Java A rice-fish system is a rice polyculture , a practice that integrates rice agriculture with aquaculture , most commonly with freshwater fish . It is based on a mutually beneficial relationship between rice and fish in the same agroecosystem .
For example, trout and juvenile salmon are less tolerant of degraded water quality and require a more rapid water turnover than catfish or tilapia. [18] The flow rate necessary to maintain water quality can also change through the year, as the temperature changes and the cultured species grow larger.
