A Comparison of the Otolith and Scale Methods of Ageing, and the Growth of Sarotherodon Mossambicus (Pisces: Cichlidae) in a Venda Impoundment (Southern Africa)

Abstract

Otoliths and scales were used for age and growth determinations of Sarotherodon mossambicus in the Luphephe-Nwanedzi impoundment, a subtropical man-made reservoir in Venda, northern South Africa. Two rings are deposited annually on the otolith whereas only one ring Is deposited on the scales. The growth of S. mossambicus in the Luphephe-Nwanedzi impoundment is compared to other S. mossambicus populations in South Africa.
