Summary

PCR-RFLP analysis of mitochondrial DNA (NADH-3/4 gene and the control region) of the Benguelan bearded goby Sufflogobius bibarbatus revealed weak, but significant genetic differentiation (overall FST = 0.137) that could not be predicted by hydrodynamics alone, thus warranting further investigations to understand the forces behind population divergence within an ecosystem having complex dynamics.
