An account is given of observations on two dolphin species Sousa plumbea and Neophocaena phocaenoides which belong to the typical fauna of the Indus Delta. Sousa is a permanent inhabitant…
The observation of 1,194 finless porpoises made through 11,549 km of sighting cruises in the Inland Sea and some ancillary observations provided the following informations. The porpoise migrates annually to…
The purpose of this study was to gather base-line life history data on the harbor porpoise. The information presented here describes only those aspects which would affect a census. During…
The distribution, movements, and relative population abundance of harbor porpoises were studied in the Fish Harbour region of New Brunswick, Canada (lat. 44°59'30"-45°01'00"N, long. 66°54'00"-66°57'00"W), from 1970 to 1978. In…
The density and total population size of harbor porpoise along the coasts of California, Oregon, and Washington are estimated from ship surveys using line transect methods. Surveys were completed between…
We conducted aerial surveys in September 1984 and September and October 1985 to determine the abundance of harbor porpoise along the coasts of California, Oregon, and Washington. Two observers and…
Results of nine whale sighting cruises in the Japanese coastal waters in 1983 through 1986 and some additional cruises provided following conclusion. Dall's porpoises inhabit waters below 24°C, but the…
Dorsal fin photographs of Dall's porpoise, Phocoenoides dalli, were taken in northern Puget Sound, Washington in order to assess the feasibility of using photo-identification techniques in studies of this species.…
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…
