COMMENTARY
Risks of the introduction of tilapia (Oreochromis sp.) (Perciformes:
Cichlidae) in aquatic ecosystems of Chile
A call of attention is made over the possible introduction of red tilapia (Oreochromis
sp.) for aquaculture in Chile. The so-called monosex (all male) culture, considered by some as the solution for unwanted
reproduction and for avoiding risks for biodiversity, are analyzed, and the falsehood of this argument is demonstrated. Special
emphasis is given to the tilapia culture in marine areas. Threats to biodiversity are stressed.
Key words:
tilapia, monosex
cultures, biodiversity
