(...) Brody (1945) fitted an allometric equation to heart mass (kg) as a function of body mass (kg) for adult mammals ranging in body size from 0.01 to over 100,000…
Developments in Marine Biology (1995)
Dolphins and porpoises spend the majority of their lives underwater, out of the view of human observers. Consequently, scientists have relied on indirect means to study the foraging ecology of…
Report of the International Whaling Commission (1994)
Between 1982 and 1993, 55 coastal locations throughout Mexico were visited to investigate mortality of small cetaceans. A total of 139 records concerning the use of small cetaceans by fishermen…

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,…
Report of the International Whaling Commission (1994)
In 1988 and 1989 we monitored the fish terminal of Pucusana, central Peru, for 259 and 233 days respectively, and observed 1,613 and 1,292 small cetaceans landed. The estimated total…

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…
Report of the International Whaling Commission (1994)
Information on small cetacean mortality in Peruvian fisheries is reviewed for the 1990-1993 period, i.e. after the national ban on cetacean exploitation. Most ports along the Peruvian coast were sampled…
Report of the International Whaling Commission (1994)
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…
