Best Choice Some Concerns Avoid

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.

RISK OF ESCAPES TO WILD STOCKS

Tilapia readily invades and reproduces in warm waters where they are introduced. Non-native tilapia populations have been found to compete with, supplant, or “devastate” wild cichlids and other native species. Escapees are expected in open systems (nets, cages, and flow through raceways), meriting concerns. Even relatively closed systems (ponds, recirculating tanks), are still compromised by storm events.

RISK OF DISEASE AND PARASITE TRANSFER TO WILD STOCKS

There are few reports of disease and parasite transfer from tilapia introductions. Where they exist, organically certified tilapia farms are required to focus on preventing outbreaks by maintaining natural environments and behaviours, and infections are treated promptly.

RISK OF POLLUTION AND HABITAT EFFECTS

Effluent water from US based Tilapia aquaculture operations is typically used for agriculture rather than being released into natural water bodies.

EFFECTIVENESS OF THE MANAGEMENT REGIME

The US has recently implemented national effluent limitation guidelines and Best Management Practise plans for aquaculture, and the US management regime is effectively enforced.

IMPORTANT QUESTION TO ASK
