| Summary: | Introduction of alien fish species has resulted in major global change, harming native species and
communities throughout the world. The main objectives of this review were to examine the species
composition, ecology, and distribution of alien fish species in natural water bodies and evaluate the
role and contribution of alien fish species through aquaculture to socio-economic development in
Malaysia. The rate of introduction and the number of alien fish species introduced into local habitats
have greatly increased since the early twentieth century. A statistical analysis of habitat differences
among native fish species in Malaysia indicated that differences in fish assemblage structure in various
sites was associated with differences in physical habitat. However, the occurrence of alien species
has not only changed the structure of native ichthyo-fauna groups but has also caused ecological
damage and economic harm to local fishermen. At present, alien fish species inhabit diverse environments
including highland and isolated streams, rivers, rice fields, swamps, drainage areas, dams and
reservoirs, lakes created from former mining areas, and estuaries in Malaysia. The examination of
species composition, distribution and movement of alien fish in natural habitats revealed that these
species have seriously spread and are now distributed in diverse aquatic habitats of Malaysia. This in
turn provided evidence that there are no restrictions or limitations to the spreading of alien fish species
in the natural habitats of Malaysia. |
