Marine Mammal Sci (1994)
The rate of occurrence of click trains of two harbor porpoises (Phocoena phocoena) were counted during 14 nights. We developed an echolocation signal detection system that was harnessed to a…
Review of gillnet fisheries and cetacean bycatches in the northeastern Indian Ocean
Lal Mohan, R. S.
Report of the International Whaling Commission (1994)
Small cetaceans and some great whales become entangled and die in gillnets in a variety of fisheries in the northeastern Indtan Ocean. Information on operational details, present status and future…

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…
