A stunted population of Oreochromis mossambicus occurs in the Matiovila Hot Sulphur Spring in the Kruger National Park. The growth of the fishes can best be described by the Von Bertalanffy equation L, = ^^(l-e0154^028^) mm SL. Breeding occurs throughout the year and the smallest sexually mature female was 35 mm SL. The fish from this locality were morphometrically compared to another stunted population and to a population of 0. mossambicus from a large impoundment. Speculative reasons for and advantages of stunting are presented
