Nile perch (Mputa), was introduced into lakes Kyoga, Victoria and Nabugabo from lake Albert. The purpose of the introduction was to increase fish production in these lakes by letting the Nile perch feed on the small sized haplochromines (Nkejje) which were abundant in these lakes and converting them into a larger table fish . It was, however, feared that Nile perch would prey on and deplete stocks of the native fishes and affect fish species diversity. Nile perch became well established and is currently among the three most important commercial species. It is presently the most important export fish commodity from Uganda.Considerable changes have taken place in the yield and in life history
