**Invasive species

Tilapias were first introduced into Hong Kong for aquaculture. However, those individuals that escape from fish farms become an invasive species and pose a threat to the surrounding habitat, due to their high growth rate, omnivorous diet, and lack of natural predators.

Omnivores are organisms that have a mixed diet of both plant and animal origins, and are able to survive on either one of them. The following organisms are also opportunistic scavengers.
