Summary
Research on pelagic birds and mammals in the southern Benguela region has to date concentrated on the breeding species of seabirds and on the Cape fur seal Arctocephalus pusillus. The status of knowledge of non-breeding seabirds and cetaceans is poor to non-existent. Research has so far concentrated on distribution, abundance, diet and land-based observations of breeding biology. Future research should include those species as yet little known and should aim at collecting information which can be used to obtain a real understanding of the relationships between pelagic birds and mammals and their prey within the southern Benguela region. This knowledge should then be used to predict the effect of changes within the system such as those due to the commercial fishery.
