Interactions between cetaceans and gillnet and trap fisheries in the Northwest Atlantic
Read, A. J.
Report of the International Whaling Commission (1994)
Gillnet and trap fisheries of the Northwest Atlantic and their potential for cetacean entanglement are reviewed. Ten major categories of passive fisheries are identified, five of which are known to…
A note on odontocete mortality from fishing gear entanglements off southern California
Heyning, J. E.; Lewis, T. D.; Woodhouse, C. D.
Report of the International Whaling Commission (1994)
Strandings and sightings data of toothed whales entangled in fishing gear are documented for the Southern California Bight from 1975-90. Entanglements involve three fisheries: a nearshore set gillnet fishery; an…
Refractive index in the cornea of a harbor porpoise (Phocoena phocoena) measured by two-wavelengths laser-interferometry
Kröger, R.H.H.; Kirschfeld, K.
Aquatic Mammals (1994)
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…
Development, sexual dimorphism, and individual variation in the skeleton of the finless porpoise, Neophocaena phocaenoides, in the coastal waters of western Kyushu, Japan
Yoshida, Hideyoshi; Shirakihara, Miki; Takemura, Akira; Shirakihara, Kunio
Marine Mammal Sci (1994)
Development, sexual dimorphism, and individual variation were examined in the skeleton of the finless porpoise in the coastal waters of western Kyushu, Japan. Skulls ceased growing by 4 yr. Postcranial…

Gearin, P. J.; Melin, S. R.; DeLong, R. L.; Kajimura, H.; Johnson, M. A.
Report of the International Whaling Commission (1994)
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…
A note on artisanal fisheries interactions with small cetaceans in Mexico
Zavala-Gonzalez, A.; Urban-Ramirez, J.; Esquivel-Macias, C.
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…
Morphometric comparison of the epidermis in several cetacean species
Jones, F. M.; Pfeiffer, C. J.
Aquatic Mammals (1994)
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…
Swimming behaviors and speeds of wild Dall’s porpoises (Phocoenoides dalli)
Law, T. C.; Blake, R. W.
Marine Mammal Sci (1994)
(...) Several researchers have obtained accurate speed data on unconfined cetaceans using a variety of techniques. Hui (1989) analyzed video tapes of Delphinus delphis and Stenella attenuata filmed from a…
