Assessment of the population structure of the South African sardine Sardinops sagax using a multi-method approach and the morphological and molecular characterization of a stock-di...
Published 2018“…Fish stocks are typically identified based on the observation of differences in genetic and/or phenotypic characteristics between fish from discrete units. Recent deliberations on the management of the South African purse-seine sardine fishery recognises the likely existence of two stocks, one on the west and another on the south coasts, following studies that have documented spatial variability in several phenotypic characteristics of this species around South Africa. …”
