Summary: Food webs are often studied in terms of predator-prey interactions, but the role of scavenging is often neglected. This study used baited remote underwater video surveys to investigate the taxonomic richness of consumers, their interactions, and the consumption dynamics of discarded fish in a coastal fishing ground. The findings show that discards attract a wide variety of species and there is competition among discard consumers, as well as predator-prey interactions.

Summary: In this paper, two video processing techniques are presented for contact-less estimation of the Respiratory Rate (RR) of framed subjects. Motion-related variations in video signals are exploited to identify respiration and estimate the RR over time. The methods rely on motion magnification algorithms to enhance respiration-related movements and perform spatial decomposition and temporal filtering to extract breathing information. The accuracy of the methods is assessed by comparison with reference data, and the phase-based method demonstrates superior performance in RR estimation.

Summary: Global studies suggest that cephalopods have benefited from climate change. However, in most areas, long-term cephalopod data sets specific to each species are lacking, making it difficult to analyze their response to environmental changes. Our study shows that by combining historical research with recent data sets, it is possible to fill this gap and describe long-term ecological changes. We observed significant changes in cephalopod biodiversity at the species level in the North Sea over the past 100 years.

Summary: The oceanic whitetip shark, currently classified as Critically Endangered, is often incidentally caught by fisheries targeting other species. This study analyzed observer data from the western Indian Ocean to understand the factors influencing the capture of this species. Sea surface temperature and nitrate concentration were found to be the most important variables predicting the probability of capturing an oceanic whitetip shark. The study also identified higher capture probabilities in fish aggregating devices compared to free schools of tuna.

Summary: This study investigated the exploitation patterns of pulse trawl (PUL) and tickler chain beam trawl (TBT) fishers in harvesting flatfish populations. The results showed that both types of fishers concentrated their efforts in the core of the flatfish patches, using systematic fishing tactics. The catch rates in the core were higher than the background catch rates, but decreased over time due to resource depletion and interference, with interference having a larger impact on TBT fishers.

Summary: This study demonstrates that harbor porpoises exhibit strong avoidance behavior and reduced surfacing frequency in response to pinger sounds, indicating the effectiveness of pingers in reducing bycatch. However, there is also a diversity in behavioral responses, with some porpoises not reacting to pinger sounds at all. This suggests that pinger use should be carefully considered and alternative mitigation measures may need to be explored.

Summary: Human activities at sea are becoming more complex, requiring adaptable management interventions to mitigate their cumulative effects on biodiversity conservation. Coastal cetaceans, particularly harbour porpoises, are threatened by bycatch and the indirect effects of repeated exposure to disturbances such as acoustic disturbances. The prevalence of pingers, used to mitigate bycatch, can affect both bycatch rate and the population consequences of noise disturbance. Understanding the physiological effects on reproductive decisions and behavioural responses to noise is crucial for evaluating the cumulative impacts of bycatch and its mitigations.

Summary: Sustainable management of fish stocks requires understanding the stock structure and connectivity of habitats. Cod in the Sound in the western Baltic Sea display complex connectivity patterns with the neighbouring stock in Kattegat. Historical tagging data and contemporary growth data were used to assess the ecological connectivity between the Sound and Kattegat, revealing considerable connectivity during the spawning season. The findings emphasize the need for further examination of the stock structure of cod in the western Baltic and adjacent areas.

Summary: This study investigates the catch rates of various cod pot designs for Baltic Sea with the aim of reducing the negative impact of seal populations on gillnet fisheries. The findings show that volume and soak time are positively correlated with catch rates, and round bottom-standing pots with a fish holding chamber, funnels, and 5 entrances have the highest catch rates. These findings are important for the development of cod pots that can be used in high seal density areas, reducing carbon emissions and minimizing bycatch of marine mammals and sea birds.

Summary: DNA barcoding and morphometric analyses were used to identify different species of Alloteuthis in Guinea Bissau and along the Atlantic coast. The results showed the presence of A. africana, A. subulata, and A. media, with A. media having the northernmost distribution and being the only species identified from the Irish shelf and North Sea. The phenotypes of A. media varied substantially across its geographic range, which explains the difficulties in morphological identification and suggests the need for regional identification guides to support fisheries management.
