Growth and reproduction in harbour porpoises (Phocoena phocoena) in Icelandic waters
NAMMCO Scientific Publications, 2003 A total of 1,268 harbour porpoises were obtained from fishing nets in Icelandic coastal waters from September to June in the years 1991 to 1997. Foetal sex ratio was 1.2:1 (male:female). The bias towards males increased further among older animals in the

Environmental DNA, Volume 8, Issue 4, July‐August 2026.Species‐specific eDNA qPCR assays were developed and validated for blue, fin, and sei whales and were tested alongside visual surveys in the northwest Atlantic. Results show strong concordance for fin whales, demonstrating eDNA's value for enhancing offshore monitoring of at‐risk large whales.

Harbor porpoise (Phocoena phocoena) reactions to pingers
Marine Mammal Science, 2018 AbstractThe use of acoustic alarms (pingers) has been mandated in several gill net fisheries around the world. Even though pingers have shown to reduce the incidental catch there are still questions to be answered in relation to effective range, habituation and displacement. In the present studies, the vocalization behavior of porpoises was recorded in

Harbour porpoises (Phocoena phocoena) in the North Atlantic: Biological parameters
NAMMCO Scientific Publications, 2003 Biological parameters for harbour porpoises are reviewed throughout their range in the North Atlantic. Most information is based on studies of a combination of directed catches, bycatches and strandings.

Marine Mammal Science, Volume 42, Issue 3, July 2026.ABSTRACT Studying habitat use of cetaceans that spend most of their lives underwater poses challenges, prompting the use of complementary methods. Non‐invasive methods, land‐based surveys (LBS) and passive acoustic monitoring (PAM), were used to characterize occurrence patterns of beluga whales, harbor porpoises, and vessels in the Saguenay–St ...
