Invasiveness
The Mozambique tilapia is an invasive species in many parts of the world, having escaped from aquaculture or been deliberately introduced to control mosquitoes. It has been nominated by the Invasive Species Specialist Group (ISSG) as one the 100 worst invasive species in the world. It can harm native fish populations through competition for food and nesting space, as well as by directly consuming small fish. In Hawaii, striped mullet Mugil cephalus are threatened because of the introduction of this species. Mozambique tilapia may also be responsible for the decline of the desert pupfish, Cyprinodon macularius, in California's Salton Sea.
