Cultured and Ornamental Exotic Fishes of Bangladesh : Past and Present

Exotic fishes have been introducing in Bangladesh since 1950; mainly for increasing aquaculture production and serving ornamental purposes; but there is no systematic record of these fish species is maintained in Bangladesh. Still new species are introducing every year. These exotic species are playing a vital role in the total fish production as well as generating income and employment opportunities. Several species are also proved and considered as threat to the native species. In this work, status of exotic fishes are provided with special emphasis on brief description of their introduction, morphology, food and feeding, breeding, impacts and economic importance. We believe, this document would help those people who are interested in fish and Bangladesh fisheries and also working on exotic fishes, especially researchers, teachers, students involved in fisheries sector as well as aquarists too.
