ABSTRACT

This report summarizes the available information on the distribution, abundance and feeding habits of cetacean, pinniped and sirenian mammals, as well as the information on interactions between these species and fisheries throughout the world. A catalogue of marine mammal species, their population sizes, distributions and diets, is followed by an area by area account of marine mammals, fisheries, and their interactions.

Hyperlinks to non-FAO Internet sites do not imply any official endorsement of or responsibility for the opinions, ideas, data or products presented at these locations, or guarantee the validity of the information provided. The sole purpose of links to non-FAO sites is to indicate further information available on related topics.
