| Comments | Reintroduced in 1972. Elimination of aquatic macrophytes by the redbelly tilapia led to the observed declines in populations of the golden shiner, eastern mosquitofish and green sunfish since this resulted to the loss/decrease of vegetative cover for either spawning or protection against predation of these species (Ref. 13058). Due to its high degree of adaptability the species has spread rapidly in fresh and even marine waters. It is particularly common in irrigation ditches in California, Arizona and Texas.
