A programme to assess the cetacean by-catch in the Irish and UK set gillnet fisheries in the Celtic Sea was conducted from August 1992 to March 1994 using volunteer observers.…

This report provides harbor porpoise bycatch estimates for 1994 and 1995. The analysis required adjusting for changes in data collection methods that went into effect in June 1994, in which…
The blubber thicknesses of 5 male and one female harbour porpoises were measured ultrasonically in 9 positions on the body over various periods of time. Most animals were immature and…
The population structure of harbour porpoises from British and adjacent waters was studied by examining variability in a 200 bp (base pair) section of the control region of mitochondrial DNA…
In July 1990, an observer program was established to collect data on the bycatch of the drift and set gillnet fisheries operating off the coast of California. These data are…
We collected testes from 62 male harbor porpoise (Phocoena phocoena) incidentally caught in gillnets of commercial fisheries in the Gulf of St-Lawrence, in June-July- August. In adults (≥4 years), both…
This paper reviews and summarises published and unpublished information on harbour porpoises in Irish waters and presents results of recent research. Harbour porpoises have been recorded from all Irish coasts…
A total of 433 skulls of harbor porpoises, Phocoena phocoena, were examined to evaluate geographical variation within the western North Atlantic, using analysis of covariance and discriminant analysis based on…
Harbour porpoises are widely distributed in the seas around Denmark. Total abundance in Danish waters is estimated as approximately 100,000 animals. Population density varies considerably by area. There are probably…
The seasonal distribution of harbour porpoises in US Atlantic waters is explored by examining aerial sightings made by the CeTAP survey between 1978 and 1988. Sightings rates were very low…
