Linefish status report: The Natal stumpnose as an example
Radebe, P.V., Mann, B.Q. and Beckley, L.E. (1999) Linefish status report: The Natal stumpnose as an example. In: 10th Southern African Marine Science Symposium (SAMSS 2000): Land, Sea and People in the New Millennium, 22 - 26 November, Wilderness, South Africa.
Based on detailed literature surveys, all available information about 70 priority species in South African linefishery has recently been compiled into individual species status reports. Major aspects covered in the report include: distribution, habitat, migration, fishery sectors targeting this species, biology and population dynamics, biological reference points, current status indicators, current regulations and research priorities. This poster uses Rhabdosargus sarba commonly known as Natal stumpnose as an example to illustrate the format of the status reports and to highlight areas where there are gaps in our knowledge. R. sarba is a sparid bream that is common in subtropical and tropical inshore waters and estuaries throughout the Indo-Pacific. It is fairly abundant in KwaZulu-Natal waters where juveniles and sub-adults are conspicuous members of estuarine fish communities. Past research on their biology has been focused on diet, food selectivity and habitat as well as some aspects of their reproductive biology. The status report for R. sarba revealed that little information is available on the age and growth of this species. Further, the status of the stock and biological reference points are unknown. These aspects are currently being addressed in a research project at ORI and progress will be indicated on the poster.
