dc.description.abstract The clupeoid Etrumeus whiteheadi, known locally as the round herring, is an important component of the commercial purse-seine catch off South Africa. Three methods are employed to estimate the growth of juvenile round herring: examination of annual hyaline rings on fish otoliths, examination of daily growth increments on the otoliths, and analysis of length frequency distributions. The results show that fish smaller than 120 mm are less than one year old and that analysis of daily growth increments is unreliable for bigger fish. The problems of determining the age of fish on the basis of counts of the number of hyaline rings is also addressed by reference to a model which can be applied to any species with a protracted spawning period. en_ZA
