Age, growth and reproduction of the pelagic goby Sufflogobius bibarbatus was investigated for males and females caught in demersal trawls between the Orange River and Port Nolloth on the west coast of southern Africa. Females had larger otoliths than

Catch rates of Agulhas sole Austroglossus pectoralis from bottom trawls conducted during research surveys over the period 1986–1992 were compared to bathymetry and sediment types. The boundaries of sole distribution are influenced by water depth, c

Routine ageing of planktonic eggs requires mathematical models to describe the relationship between the time elapsed after spawning to reach a developmental stage and the ambient temperature of the water in which the eggs are developing. In this stud

Catch rates of Agulhas sole Austroglossus pectoralis from research trawls were compared with depth of sea bed, bottom temperature and oxygen concentration. Data were from 10 research surveys conducted during the years 1986–1992 in autumn and spring

The main focus of this study was to gain an understanding of the distribution of juvenile (10–24 cm Lt ) Agulhas sole and some factors that could govern their dispersal and migration. The hypothesis that the size and the locality of mud patches det

The study was aimed at establishing whether there was a relationship between seasonal trends in sea surface temperature (SST) on the spawning grounds and the dry mass of hydrating oocytes and batch fecundity of pilchard Sardinops ocellatus in the nor

Seasonal and spatial trends in gonad weight of some 68 000 female pilchard sampled in the northern Benguela system over the period 1952–1979, and especially the better-sampled years 1965–1979, were assessed. There were large variations in fish ab
