Mapping Seasonal Interaction Risk Between Harbour Porpoises and Gillnet Fisheries to Inform Management Thresholds

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 7, July 2026.
ABSTRACT When empirical bycatch data are limited, risk‐based assessments offer a valuable tool for identifying areas where marine mammals and fisheries are most likely to interact. The harbour porpoise (Phocoena phocoena) is among the most vulnerable to incidental capture in gillnet fisheries.

Habitat characteristics of the shelf distribution of the harbour porpoise (Phocoena phocoena) in the waters around the Faroe Islands during summer

NAMMCO Scientific Publications, 2003
Observations from a large number of seabird line-transect surveys conducted in Faroese waters are used to derive some general conclusions regarding the distribution of harbour porpoises (Phocoena phocoena) in the region using estimates of encounter rates

Trends in Aquatic Environmental DNA Research in Alaska

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Environmental DNA (eDNA) analysis is an emerging tool with significant potential to advance biomonitoring, particularly in remote and logistically challenging environments. To evaluate the state of eDNA research in Alaska, we conducted a literature review and a regional survey and results provide the first comprehensive overview of eDNA research in ...

Feeding ecology of harbour porpoises Phocoena phocoena stranded on the Galician coast (NW Spain) between 1990 and 2018

Endangered Species Research
Diet studies on the endangered and genetically distinct Iberian population of the southern harbour porpoise Phocoena phocoena are scarce. The present study provides updated information on the feeding ecology of this cetacean along the Galician coast (NW ...

Summer Abundance of Harbour Porpoises (Phocoena phocoena) in the Coastal Waters of Iceland and the Faroe Islands

NAMMCO Scientific Publications, 2020
This study presents the first fully corrected abundance estimates for the harbour porpoise (Phocoena phocoena) for Iceland and the Faroe Islands. In both regions reliable estimates are needed to assess the impact of by-catch and other threats to harbour ...

Species‐Specific qPCR Assays for Detecting Blue, Fin, and Sei Whales (Balaenoptera spp.) From Offshore Environmental DNA Samples

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.

Will harbour porpoises (Phocoena phocoena) habituate to pingers?

J. Cetacean Res. Manage., 2023
Large bycatches of harbour porpoises (Phocoena phocoena) occur in gillnet fisheries throughout the Northern Hemisphere. Several mitigation measures, including acoustic deterrent devices or ‘pingers’, have been used in efforts to reduce this bycatch. The potential exists for harbour porpoises to habituate to pingers, thus reducing their effectiveness ...

Conserving the World's Specialist Riverine Birds

WIREs Water, Volume 13, Issue 4, July/August 2026.
Specialist riverine birds constitute a diverse bird group globally, highly adapted to rivers and streams. They are at risk from multiple threats to rivers, riparian zones and river catchments including impoundment, hydropower and abstraction; land‐use changes including urbanization and agricultural intensification; traditional and emerging pollutants ...

Assessing the Underwater Impact of Aerodynamic Noise From Offshore Wind Turbines

Wind Energy, Volume 29, Issue 7, July 2026.
ABSTRACT The growing demand for offshore wind energy has led to a significant increase in wind turbine size and to the development of large‐scale wind farms, often comprising 100–150 turbines. However, the environmental impact of underwater noise emissions remains largely unaddressed.

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.
