BIOLOGY
Tilapia is a generic name used to describe groups of fish called cichlids that are native to Africa. Tilapia are hardy, freshwater fish that tolerate a wide range of water conditions. They inhabit warm ponds, lakes and streams, and reproduce in fresh and brackish water. They mainly feed on phytoplankton, zooplankton and algae. They reach a maximum size of 45cm and a weight of 2kg.

ADVICE
Tilapia can be farmed in a number of ways, which varies according to country and size of production. They can be produced in open systems, using pens submerged in freshwater bodies, or in raceways that are flushed by streams. They can also be produced in semi or fully closed systems such as ponds and recirculating tanks. Environmental impacts of these production methods vary greatly, and as with all farmed species, can vary between farms.Until such time as MCS is able to fully assess the production methods between countries and identify the most sustainable producers we are limited to identifying the production method with the least environmental impact.Tilapia farmed in enclosed and/or recirculating systems prevent the risk of escapes and water pollution to the surrounding environment. Tilapia are also herbivores and therefore do not require feed based on wild fish, although some fish oil may be included in the feed. They are however farmed in high stocking densities. When buying any farmed fish ask your fish supplier if they have a buying policy to ensure they only source fish from farms with high environmental and welfare standards.
