Seventy-eight harbour porpoises, Phocoena phocoena, (33 females, 45 males) were obtained from the summer (June-September) cod fishery incidental-by-catch in the Gulf of St. Lawrence, and examined for the presence of…
A global review of mortality of porpoises in gillnet fisheries indicates that individuals of all six species become entangled and die in gillnets. Harbor porpoises Phocoena phocoena are taken throughout…
This note summarises available information on bycatches of harbour porpoises in German waters since 1987. Most information is for the cod set net fishery in Schleswig-Holstein. More recently, information on…
The refractive index of the cornea of a harbor porpoise eye was measured by two-wavelengths laser-interferometry. In the thickest part of the cornea a refractive index of about 1.53 was…
Thousands of porpoises die annually in monofilament gillnets. Simple net modifications may alleviate the problem. In June through August 1988, we quantified harbour porpoise (Phocoena phocoena) reactions to weighted vertical…
The harbour porpoise (Phocoena phocoena) is the only cetacean incidentally caught in significant numbers by the Danish fishing fleet and there is some concern that the populations in Danish waters…
Cetacean strandings have typically been classified into two types: 1) single strandings (including a mother/offspring pair); and 2) mass strandings. Singly stranded cetaceans have been reported world-wide wherever populations of…
A cooperative study based on an agreement between the National Marine Fisheries Service and the Makah Indian Tribe was conducted during 1988-90 to assess the nature and magnitude of harbor…
Epidermal thickness and relative papillary height of the skin from the urogenital region were compared with values from the ventral aspect of the flipper and the mid-dorsal body wall. Data…
The reproduction and reproductive seasonality of 365 Danish harbour porpoises (Phocoena phocoena (L.)) incidentally caught in various gill nets or stranded, was studied. The animals were collected from all Danish…
