This field guide covers the major resource groups likely to be encountered in the fisheries of Namibia. These include seaweeds, shrimps, lobsters, crabs, bivalves, gastropods, cephalopods, hagfishes, sharks, batoid fishes, chimaeras, bony fishes, turtles, seabirds, and marine mammals. The introduction outlines the geographical, environmental, and ecological factors influencing fisheries, and the basic components of the fisheries of Namibia. As an aid to identification to higher taxonomic levels, a pictorial index to families is included and most groups are preceded by an illustrated guide to orders and families. Each resource group includes general remarks, an introduction to the technical terms and measurements pertinent to that group, and a guide to species likely to be encountered in fisheries. Each species account provides scientific nomenclature, FAO common names, sizes, notes on fisheries, habitat and biology, diagnostic features, and one or more illustrations. An annotated checklist of sharks, batoid fishes, chimaeras, bony fishes, and marine mammals, and a list of important references are appended. The introduction and guide sections are fully indexed. Finally, 88 colour photographs are presented of fishes caught mostly by trawl.
