Abstract:[EN]A good relationship between the variability in measurements of Cape hake Merlllccills capensi.\ biomass during winter and summer swept-area research surveys and sea surface temperature off southern Namibia for the years 1983-1990 is presented. The results call into question [he hypothesis that hake density is related to biomass and imply that abnonmally warm summers could support higher catches, regardless of the state of the stock. A hypothesis that anomalous warm conditions could induce hake to concentrate closer to the sea bed, making them more susceptible to bottom trawling, is presented.
