Scientific Committee Meeting Documents (2002)
Fifteen fishing centres on the northern and central coasts of Peru, including large industrial fishing ports and smaller fish landing sites were surveyed for cetacean landings periodically over 29 months,…
Post-mortem findings and causes of death of harbour porpoises (Phocoena phocoena) stranded from 1990 to 2000 along the coastlines of Belgium and northern France
Jauniaux, T.; Petitjean, D.; Brenez, C.; Borrens, M.; Brosens, L.; Haelters, J.; Tavernier, T.; Coignoul, F.

Between the years 1990 and 2000, an attempt was made to determine the causes of death of 55 harbour porpoises stranded along the Belgian and northern French coasts. From 1990…
The effect of acoustic harassment devices on harbour porpoises (Phocoena phocoena) in the Bay of Fundy, Canada
Johnston, Dave W.
Biological Conservation (2002)
Many salmon aquaculture sites in the Bay of Fundy employ acoustic harassment devices (AHDs) to deter seals from approaching fish pens. These devices may also exclude harbour porpoises (Phocoena phocoena)…
Abundance of harbour porpoise and other cetaceans in the North Sea and adjacent waters

Journal of Applied Ecology (2002)
The status of small cetaceans in the North Sea and adjacent waters has been of concern for many years. Shipboard and aerial line transect surveys were conducted to provide accurate…
Small-scale population structure of eastern North Pacific harbour porpoises (Phocoena phocoena) indicated by molecular genetic analyses
Chivers, S. J.; Dizon, A. E.; Gearin, P. J.; Robertson, K. M.
Journal of Cetacean Research and Management (2002)
Concern about the conservation and management of harbour porpoise (Phocoena phocoena) populations, which have experienced relatively large incidental fishery kills in localised areas throughout their range, has prompted research to…
An experimental study of postmortem ocular fluid and core temperature analysis in incidentally captured harbour porpoise (Phocoena phocoena)
Hood, C; Daoust, P-Y; Lien, J; Richter, C
NAMMCOSP (2003)
Determination of elapsed time since death in small cetaceans can be important to our understanding of the nature of their interactions with fishing operations. This pilot study was conducted to…
