| SPECIES |
Tilapia |
| SCIENTIFIC NAME |
Oreochromis spp., Sarotherodon spp., Tilapia spp. |
| MARKET NAMES |
Nile tilapia, Mozambique tilapia, Blue tilapia, St. Peter’s fish |
| SUSHI NAMES |
Izumidai |
| DESCRIPTION |
Various estimates of the amount of fish protein in, to fish protein out for farmed Tilapia are less than 1:1 in nearly all cases. This indicates that tilapia culture results in a net gain of edible fish protein. Due to their high reproductive capacity and the ability to establish self-reproducing populations in a variety of habitats, however, risk of escapes to wild stocks are a moderate to high conservation concern, in all regions. In the US, management is deemed highly effective; effluent and risk of disease and parasite transfer are minimized, whereas farming in Central America and Asia is deemed to have moderate to high concerns in these categories.

| USE OF MARINE RESOURCES |
Various estimates of the amount of fish protein in, to fish protein out for farmed Tilapia are less than 1:1 in nearly all cases. This indicates that tilapia culture results in a net gain of edible fish protein.
|
| RISK OF ESCAPES TO WILD STOCKS |
Tilapia are native to Africa and the Middle East, however, their adaptability to a wide range of environmental conditions have allowed them to invade a range of non-native habitats. Therefore, the risk for escape in tilapia aquaculture productions with nets, cages, and raceways, as well as unenclosed ponds and tanks is ranked “high”.
|
| RISK OF DISEASE AND PARASITE TRANSFER TO WILD STOCKS |
Though there are few reports of disease and parasite transfer from tilapia introductions, stocked tilapia can become infected from wild stocks prompting a “moderate” ranking for tilapia culture in nets, cages, and raceways, as well as unenclosed ponds and tanks.
|
| RISK OF POLLUTION AND HABITAT EFFECTS |
Integrated farms in the US ranks as a “low” conservation concern, as effluent is used for agriculture rather than being released into natural water bodies. However, internationally, a lack of demonstrated effectiveness of effluent management warrants caution and a rating of “moderate” risk for tilapia. The risk of pollution is likewise moderate for semi-intense and intensive operations that are closed to the environment. There is growing concern for pollution in China and Central America where rapid development of intensive cage culture continues.
|
| EFFECTIVENESS OF THE MANAGEMENT REGIME |
South American countries appear to have underdeveloped management plans that merit “moderate” levels of concern.
