Resumo:
A reduction in native fish stocks and the need to increase fish production for food, recreation, ornamental purposes and to control disease vectors and weeds have often justified and led to introduction of non-native fishes. Some of these introductions have been followed by benefitial and others by undesirable consequences. For instance introduction of the Nile perch Lates niloticus L. and several tilapiine species into lakes Victoria and Kyoga, and the clupeid Limnothrissa miodon into lakes Kariba and Kivu have resulted in increases in the quantity of fish available to the people around them. Predation by Nile perch and competition with introduced tilapiine species in lakes victoria and Kyoga have caused a severe decline and in some cases total disappearance of many of the native fish species.therefore the concern about fish introductions arises
