Summary: Plastic litter is widespread in Baltic fish, with microplastics being the most common form ingested. There are species-specific differences in plastic ingestion and gill retention, likely related to fish lifestyles and filtering capacity. The majority of plastic items show signs of weathering and fragmentation, but chemical contaminant levels are not different than in fish without plastic.

Summary: The Atlantic herring and Atlantic cod are two marine fish species that have successfully adapted to the brackish Baltic Sea, but face different challenges in regards to ecological adaptation and future climate change. The herring has shown strong genetic associations to salinity and temperature variation, indicating its potential for adaptation. However, its future status also depends on factors such as plankton production and competition with other species. The cod population in the Baltic Sea is threatened by overfishing, low oxygen levels, and isolation from nearby cod populations, making its situation more challenging.

Summary: The restriction of vessel power in the Gulf of Riga has been found to have limited impact on the catch structure of Baltic herring. The differences in catch structure are more influenced by season and water depth rather than vessel power. Easing the power restriction is unlikely to have a major negative effect on the sustainable management of the herring population.

Summary: Previous studies have shown that there are differences in backscattering properties of Baltic herring in different regions and seasons. The variability is believed to be due to intra-species differentiation in fish physiology and morphology, as well as fish swimbladder morphometry. This study analyzes the swimbladder morphometry and its impact on target strength of herring individuals in ICES subdivision 26, a region where Poland is responsible for herring biomass estimation.

Summary: The Baltic Sea, with its strongly stratified water structure and densely populated catchment, is one of the most polluted seas. Understanding its circulation pattern and time scale is crucial for predicting ecological issues. Research has shown that anthropogenic U-236 and U-233 are useful tracers in oceanic studies, but their application in the Baltic Sea is limited by unclear input history and inadequate monitoring records.

Summary: The prevalence of Corynosoma spp. in great cormorants and Baltic herring in the northern Baltic Sea was studied from 2014-2019. Results suggest that cormorants may act as definitive hosts for these acanthocephalan parasites. Adults were more infected than juveniles, possibly due to their larger size, and a lower prevalence was found in juveniles, potentially because of their smaller prey.

Summary: Temperature has an effect on the reproductive success and development of Baltic herring. Elevated temperature results in a faster developmental rate, lower early-stage mortality and hatching success, smaller size-at-hatch, larger yolk sac size, and a higher amount of larval malformations. Maternal traits are also associated with egg and offspring traits.

Summary: The lack of abundant recruitment of Norwegian spring-spawning herring between 2005 and 2015, attributed to North Atlantic warming, led to a significant reduction in spawning-stock biomass. The historical positive correlation between AMO and herring stock dynamics was reversed between 1988 and 2015. The North Atlantic transitioning into a negative AMO phase since 2016 may result in the end of a 10-year recruitment suppression of NSS herring.

Summary: While European policies have advanced towards an Ecosystem Approach to Fisheries Management (EAFM), limited attention has been given to the implications for its advisory system. The study found that the system heavily relies on mandatory requests from policy makers rather than enabling existing capacities to support ecosystem approaches. Social and economic dimensions were identified as the weakest aspects in the advisory process.

Summary: Lemon sole, a commercially valuable flatfish species in the northeast Atlantic, is believed to spawn between May and October with a peak between May and August. Analysis of lemon sole larvae in the northern North Sea suggests that spawning may continue into late October and November, with overwintering larvae in various developmental stages. Drift modelling indicates that historically documented spawning grounds in the northern North Sea are the source of larvae sampled during surveys in 2016-2017.

Summary: This study develops a comprehensive resilience framework to examine fishery systems across ecological, socio-economic, and governance dimensions, distilling and defining 38 attributes that confer climate resilience. The directionality and mechanism of these attributes depend on specific context, capacities, and scale, with evidence of interdependencies among them. However, meaningful quantification of the attributes' contributions to resilience in fisheries remains a challenge, as most studies focus on the ecological dimension.

Summary: This study aims to explore the definition of success for organizations working at the marine science-policy interface, and to propose a range of indicators and methods for evidencing success. The research found that success can manifest in various forms across five different scales, including impacts on the organization, policy, science, people, and ecosystems and society. Additionally, a combination of quantitative and qualitative indicators is necessary to fully capture the range of impacts, and factors such as knowledge exchange processes, diverse team composition, and organizational mission and strategy play key roles as enablers of success.

Summary: Multispecies models have been around in fisheries since the 1970s, but their operational use in fishery management is limited. This is surprising given the inherent multispecies nature of species and fleet interactions and the push for ecosystem-based fisheries management. We provide recommendations to address the impediments to the regular operational use of multispecies models.

Summary: The inclusion of ecosystem information into fish stock assessments and management advice is important for ecosystem-based fisheries management. This study provides an overview of how ecosystem trends and variability are incorporated into ICES fishing opportunities advice in the Northeast Atlantic. Around 50% of stock assessments considered ecosystem information, while the majority of management strategy evaluations did so in some way. The inclusion of ecosystem information was influenced by stock and fisheries characteristics, with pelagic species and high catch stocks having higher instances of incorporation.

Summary: The ecological and social dimensions of fisheries are being impacted by climate change. This study aims to identify key attributes of resilience in fisheries and connect them to social-ecological outcomes. By assessing 18 case studies, the researchers found that attributes such as population abundance, learning capacity, and responsive governance were the most important for building resilience. They also developed a typology and identified five fishery archetypes to guide stakeholders in improving resilience. Two pathways to resilience were observed: building ecological assets and strengthening communities, or building economic assets and improving governance.
