How estuarine-dependent are South African fishes?

Wallace, J.H., Beckley, L.E., Bennett, B., Blaber, S.J.M. and Kok, H.M. (1983) How estuarine-dependent are South African fishes? In: 5th National Oceanographic Symposium, 24 January, Grahamstown, South Africa.


Over the past 25-odd years much research has been conducted on South African estuarine fishes and their basic biology is now well understood. Due to the great abundance of juvenile fishes in estuaries it became apparent that these areas play an important role as nurseries and for this reason much has been written about the need to conserve estuaries in the face of development projects that threaten to degrade this environment. This paper reviews the results of recent research conducted along the Cape south coast in which the juvenile fish fauna was sampled from inter-tidal rock pools, from inter- and sub-tidal sandy beaches, from sub-tidal reefs down to 32m and trawled on soft substrates down to 97m.
