SCWG / EG2025NAMMCO/SC/PWWG/2025-01Pilot Whale Working Group meetingNot available yetAccess hereThe NAMMCO Working Group on Pilot Whales met from 24 to 27 November 2025 in Copenhagen to conduct a stock assessment of pilot whales in the North Atlantic.
SCWS2025Workshop: Spatial and space-time models for whale surveys with complex and non-systematic designsNot available yetAccess restrictedThe goals of this workshop were to discuss methods, best practices, and software choices for the spatial analysis of line transect data for whales, in cases where the survey design did not follow conventional approaches (e.g., co-platform surveys). Case studies, including data from the NASS 2024 project, were presented and investigated during the meeting. The workshop was hosted by the Institute for Marine Research in Tromsø.

NSP2025NAMMCO/NSP/14/Moan and BjørgeFollow-up study after four years shows reduced deterrence effect of pingers on harbour porpoises in Norwegian gillnet fishery - Moan and Bjørge, 2025 Peer-reviewed articleAbstract: 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 alternating weeks between January and April 2024. Harbour porpoises were by-caught in both pingered (9 porpoises) and control nets (25 porpoises), with most (~73%) taken in control nets. Average by-catch rates were calculated using a generalised linear mixed model (GLMM) approach. The average harbour porpoise by-catch rate was estimated at 0.061 (95% CI 0.034 – 0.098) porpoises per net km day in control nets and 0.031 (95% CI 0.011 – 0.060) porpoises per net km day in pingered nets. This shows that the by-catch rate in pingered nets was about 50% lower than in control nets (95% CI 0 – 83%). This estimate is lower (i.e. the pinger effect size is smaller) than a directly comparable study (Moan & Bjørge, 2023). Possible causes include limited sample size, the use of bait bags to attach pingers to the nets, reporting biases, and/or desensitisation/habituation of porpoises to the pinger sounds. Extra time use due to pingers was low, about two minutes per haul. The use of bait bags seems to have mitigated some, but not all the practical issues reported earlier. The pooled pinger effect size estimate using data from both Moan and Bjørge (2023) and the present study, was estimated at 72% (95% CI 44 – 89%).Moan, A., & Bjørge, A. (2025).

NSP2025NAMMCO/NSP/14/Montello et al.Pinnipeds in New York (1996–2021) are stranding less frequently but human interaction cases are increasing - Montello et al., 2025 Peer-reviewed articleAbstract: 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 density, resulting in negative interactions between humans and pinnipeds. These human interaction (HI) cases can include harassment, entanglement, and vessel trauma. Live pinniped strandings in New York, U.S.A., from 1996 through 2021 were examined to summarise characteristics, quantify the frequency and types of HI cases and assess overall spatiotemporal stranding trends. Of the 1,407 live strandings, 135 HI cases (55% involving gray seals) were documented. Notably, half of the HI cases involved entanglement in fishing gear or debris. The frequency of HI cases increased significantly over the study period, with more than one-third of cases occurring within the last 4 years. A significant positive correlation (p < 0.05) was observed between pinniped strandings (non-HI and HI) and boat access points, such as ramps and marinas, along a west-to-east gradient on Long Island. Understanding both non-HI and HI strandings is crucial to support the conservation of pinnipeds, as it provides essential insights into population trends, habitat changes, and the impact of human activities. These findings can inform targeted initiatives, such as training procedures for stranding response staff and volunteers, as well as the development of directed outreach materials, to foster greater awareness and proactive measures for species protection.Montello, M., McFarlane, W., Rickard, M., & Warren, J.
