Interactions between marine mammals and fisheries were monitored along the southwestern Atlantic coast of Argentina from Bahia Samborombon (Buenos Aires Province) to Tierra del Fuego Island. A variety of fisheries…
Many passive net fisheries exist along the Pacific coastlines of the USA (California, Oregon, Washington and Alaska), Canada (British Columbia) and the Russian Federation. Some incidental marine mammal mortality occurs…
Considerable numbers of cetaceans are killed incidentally every year during fishing operations on the Portuguese coast. Although a small number of marine mammals are caught by trawlers and fishing traps,…
In July 1990, an observer program was established to collect data on the bycatch of the drift and set gillnet fisheries operating off the coast of California. These data are…
A total of 139 types of passive fishing gear are used in Chinese marine fisheries. Finless porpoises, false killer whales, bottlenose dolphins and common dolphins are known to be caught…
The available information on the status of populations of three species of dolphins in the Black Sea is reviewed. These populations were subject to a commercial fishery from 1870 to…
The paper reports on research into the available published literature concerning those smaller cetaceans which penetrate into the Baltic Sea, bearing in mind that the Skagerrak is not included in…
We present the results of an aerial line transect census of cetaceans along the California coast during March and April 1991. This survey was the first of two aerial surveys…
As a rough measure of intelligence, brain weight: cord weight ratios in small delphinids compared favorably with, but were slightly less than , this ratio in man. Not all delphinids…
1. Assessments of anthropogenic impacts on cetaceans are often constrained by limited data on the extent to which these species use particular areas. 2. Timing porpoise detectors (T-PODs) are autonomous…
