\" Several countries report adverse ecological impact after introduction (Froese and Pauly, 2021)\"; \"In Madagascar, extreme population decline of an endemic fish is attributed to the impacts of C. rendalli herbivory on its habitat. (U.S. Fish and Wildlife Service)\"

Frequentemente, a espécie é apontada como responsável por alterações na qualidade da água, na composição do plâncton e em alterações das condições abióticas, reduzindo a sobrevivência de espécies nativas de peixes. (Latini et al. 2016)

“The main negative effects on the environment caused by T. rendalli has been due to its voracious feeding habits. In Mauritius (George 1976), Brazil (Nomura 1976, 1977), and Madagascar (Lamarque et al. 1975) T. rendalli is reported to have upset the ecology of the waters through either overpopulation, destruction of vegetation or through disturbing the ecology. It is reported that in Madagascar T. rendalli was accidentally introduced and proceeded to wipe out 3000 hectares of Ceratophyllum and Nymphaea in three years and, as a result, one valuable species of indigenous fish Paretropus petiti was almost wiped out (Lamarque et al. 1975).”
