The biology of the hottentot Pachymetopon blochii (Va. and the silverfish Argyrozona argyrozona . Comparisons between the bait, tackle and craft used in the modern fishery with those reported in the past all show minimal functional variation. along the Cape south-west coast. The effort devoted to general linefishing at the various centres around the coast is estimated and the proportion of hottentot in the catches determined. Total linefishing effort is estimated at 1 415 121 man-hours fished per year. and the . The stock is separated from sympatric stocks along the south-western coast of South Africa, increasing the need for controlled exploitation of the resource

The biology of the hottentot Pachymetopon blochii (Va. The stock is separated from sympatric stocks along the south-western coast of South Africa, increasing the need for controlled exploitation of the resource. This study focuses on several aspects of the life history of R. globiceps, and includes a study of juvenile habitat, a hatch date analysis, methods to increase precision of age estimates obtained from reading otoliths and a per-recruit assessment.

Hottentot Pachymetopon blochii . It occurs along the coast of Angola, Namibia and the South African West Coast to Cape Point and is an important commercially fished species in the Western Cape. It forms small shoals in kelp forests and over rocky reefs. Juveniles are restricted to kelp beds. What is a sea bream?
