General food habits are discussed for 11 species of small marine mammals beach-east in northern California. The collection method allowed tabulation only of the kinds, numbers, and percentages of fish,…
Serious concerns have been raised regarding the status of the harbour porpoise populations in the North Atlantic and specifically for those inhabiting Atlantic Canadian waters. In 1991 harbour porpoise in…
The most serious threat to the status of harbour porpoise (Phocoena phocoena) is incidental mortalities caused by entanglement in fishing gear. As part of an ongoing study to evaluate the…
The population status of harbour porpoises has been of concern for several years due to anthropogenic influences, especially incidental bycatch in gillnet fisheries. Proper management of a wide-ranging species such…
The Salish Sea, an area of complex oceanography and bathymetry, supports a number of apex cetacean species. In the last decade, anomalous sightings of cetaceans have become more frequent and…
Throughout its range, the distribution of the harbour porpoise (Phocoena phocoena L.) has contracted significantly in the last century, particularly in the North Sea. Reasons for this decline have been…
(...) This reports observations of odontocetes made during the summer of 1963 in central Californian waters. I made my observations aboard catcher boats of the Golden Gate Fishing Company, Point…
(...) In this report we examine the indirect exploitation of harbor porpoises, Phocoena phocoena, by the weir fishery for herring (Clupea harengus) in Charlotte County, New Brunswick, in the lower…
This study confirms earlier observations of apparently involuntary movements, strongly associated with the breathing. The movements include taxes - a dorsal flexure of the thorax and steering movements with the…
