| Summary: | Peacock bass (Cichla spp.) originates from the Neotropical environments of Brazil and Venezuela but, through
trade and smuggling for aquarium keeping, sport fishing and aquaculture, it is now an emerging concern. Yet, less
is known for Cichla spp. distribution and its ability to invade new environments. Aimed to communicate on Cichla
spp. ecology, biology and introduction schemes from Scopus, Web of Science, Google Scholar and also National
Centre for Biotechnology Information, this review also contains management strategies for invading fish species.
While Cichla spp. can displace native fish populations, this concern is explained using ecological functions,
physiological demands, direct and secondary invasion, disease tolerance and parasite spillover. Briefly, Cichla spp.
has rapid embryogenesis (72 h) and matures in short periods (11–12 months), giving it an advantage to colonize
new environments. With a large appetite, this true piscivore gains territorial control over water bodies by making
it their feeding and nursery grounds. Perceived as an emerging concern after becoming introduced, seal-off or
sport fishing were used to manage Cichla spp. but, this practice is not sustainable for the entire ecosystem. Hence,
we recommend bottom-up management that involves community participation because they interact with the fish
and have knowledge about their environment. |
