An evaluation of movement patterns of important fishery species in coastal waters of southern Africa

Movement of fishes is an integral part of their daily life, but has significant implications for fishery management. In South Africa's multi-user, multi-gear, multi-species fishery, management is challenging. To further complicate matters, many of the targeted species exhibit complex movement behaviour. Individuals may be highly resident for extended periods before dispersing long distances over short periods of time. Many species also participate in annual migrations, sometimes covering thousands of kilometres along the South African coastline. It is hypothesized that, in this region, certain commonalities exist in fish movement patterns. Understanding these commonalities will aid in the planning of future spatial and temporal management initiatives. This study will synthesize what is currently known of fish movement and migration patterns in South Africa, will investigate the connection between movement patterns and certain life-history characteristics and environmental factors, will generate a classification of movement patterns and discuss fishery management in the context of fish movement behaviour
