Abstract
Aspects of the biology of Choromytilus meridionalis were studied while investigating possibilities for cultivating mussels. Plankton samples were taken regularly, and growth, development and settlement behaviour of the larvae are discussed and correlated with results of a larval rearing experiment. Methods are described for the recording of settlement, and the results indicate annual, seasonal and local fluctuations in intensity of settlement at a number of sites. Reference is made to results obtained in Liideritz Bay. The growth rate of mussels suspended from rafts was determined and indicates considerable variation within the study area. This is discussed and aspects of the annual growth curves are presented. Water temperatures were obtained in Saldanha Bay during 2,75 years by means of a continuous recorder.Keywords
