The reintroduction grey seal hunting in Sweden – A review of hunting and seal population data (2001-2024)
This study reviews the reintroduction and development of grey seal (Halichoerus grypus) hunting in Sweden from 2001 to 2024, together with regional development of the seal population. Implementation of the hunting, together with geographical and temporal trends, as well as implications for…

Assessing shipping noise as a potential driver of harbour seal (Phoca vitulina) habitat selection
Over the past decade, anthropogenic noise from activities such as shipping has significantly increased in the ocean, raising questions on their potential impact on coastal species such as harbour seals. In this study, we assessed the spatial overlap between ships (equipped with AIS transmitters)…

Pinnipeds in New York (1996–2021) are stranding less frequently but human interaction cases are increasing
Every year pinnipeds from five different species—gray (Halichoerus grypus), harbour (Phoca vitulina), harp (Pagophilus groenlandicus), hooded (Cystophora cristata), and ringed (Pusa hispida) seals—haul out on New York’s beaches. The locations of these animals are often in areas with high human…

Follow-up study after four years shows reduced deterrence effect of pingers on harbour porpoises in Norwegian gillnet fishery
We report results from follow-up field trials testing acoustic deterrents (pingers) as a measure to reduce harbour porpoise (Phocoena phocoena) by-catch rates in coastal gillnet fisheries in Norway. Twelve gillnet fishers conducted a total of 308 fishing trips, fishing with and without pingers in…

By-catch of common minke whales (Balaenoptera acutorostrata) in Norwegian demersal trawl and longline fisheries, 2011–2020
The Norwegian High Seas Reference Fleet (HSRF) reported one minke whale (Balaenoptera acutorostrata) by-caught in demersal trawl fisheries and one in a longline in the period 2011–2020. The HSRF comprises 25–30 concurrent fishing vessels larger than 15 m total length, contracted by the Institute of…

Application of the Precautionary Approach to the Management of Marine Mammals in northern Canada
Canada is committed to managing its resources using a Precautionary Approach (PA). However, when applying this approach to Arctic marine mammals, the Government of Canada must also respect the land claims agreements it has signed with Canada’s Inuit. Under these agreements the co-management boards…

Changes in cetacean occurrence in Faxaflói Bay, Iceland, as observed from whale watching vessels
The distribution of animal species is shaped by environmental conditions and their ecological niches. The understanding of these niches is essential for conservation, especially for cetaceans, as cetacean species may adjust their geographical range in response to ecological changes. Long-term data…

Distribution and habitat use of deep-diving cetaceans in the central and north-eastern North Atlantic
Major changes in the distribution of some cetaceans have been observed coincident with changing oceanography of the North Atlantic in the last 30 years. This study aimed to improve understanding of the underlying ecological drivers of any changes in deep-diving cetacean distribution. We used data…

Large decline in hooded seal (Cystophora cristata) pup production off of northeastern Newfoundland in 2012 and 2017
Accurate data on population abundance is needed to monitor trends through time, especially for species that are commercially harvested or vulnerable to climate change related impacts. Hooded seals (Cystophora cristata) in the Northwest Atlantic whelp on drifting sea ice in three areas: Davis…

Bowhead whales spend more time in waters with colder sea surface temperatures
Marine mammals are under potential threats due to rapid ocean warming. Such threats may be especially challenging for the bowhead whale (Balaena mysticetus), an endemic arctic cetacean, because it is limited in how much further north it can go. To explore the effects of global warming on this…

Addressing epistemic injustices in species at risk assessments through improved credibility and legitimacy: case study of narwhal management in Ittoqqortoormiit
The regulation of seal and whale hunting in Kalaallit Nunaat (Greenland) belongs to the Naalakkersuisut (National Government), which is notably informed by the work of the Scientific Committee (SC) of the North Atlantic Marine Mammal Commission (NAMMCO). Since 2004, quotas were set in Kalaallit…

Previous, current and future monitoring and management of common minke whales in Norway
An account of the historical, current and possible future management of common minke whales in Norway is presented. The current management is based on an approach very similar to the International Whaling Commission’s Revised Management Procedure (RMP) and requires historical and current catch…

Developments in the Quantitative Assessment of Welfare Outcomes in Hunted Mammals Subject to Shooting
Knowledge gaps surrounding animal welfare assessment in hunted terrestrial wild mammals and seals were highlighted in the reviews by Knudsen (2005) and EFSA (2007). Following these reviews, the present paper aims to report on developments in the quantitative assessment of welfare outcomes in wild…

On the availability bias in narwhal abundance estimates
Abundance estimation of narwhals is usually done with either visual or photographic aerial surveys. The basic estimation for both methods is detection of whales at the surface, and to obtain fully corrected abundance estimates, the at-surface detections need to be corrected for the proportion of…

Needles in an ocean haystack: using environmental DNA to study marine mammals in the North Atlantic
Marine mammals in the North Atlantic have experienced severe depletions due to overexploitation. While some species and populations have now recovered, there are numerous other anthropogenic activities impacting their North Atlantic ecosystem. Studying marine mammals is often associated with…
