Spatial and temporal dynamics of an exploited reef-fish population

The successful management of the fishery for galjoen Dichistius capensis depends on an understanding of its spatial and temporal dynamics. This thesis investigates the movement of galjoen and its fishery parameters, and evaluates the role of marine protected areas (MPAs) and alternative assessment strategies. A review of the literature shows that there are examples of resident behaviour, territoriality, nomadism and migration among fish. Combinations of the above may exist within a stock. Fish movement behaviour may be plastic, but never random. Planktonic stages are capable of influencing their destination and settlement.
