Summary: Bottom trawling is a common and non-selective fishing method that raises concerns on sustainability and ecosystem conservation due to the large amounts of discarded by-catch. This study evaluated a shallow-water bottom trawl fishery using catch data from logbooks and species composition data from fisheries observers. The findings suggest that there is no significant impact on prawn stock at the current level of fishing effort.

Summary: The rapid population growth and increased demand for protein-rich foods pose a challenge for the food industry. Insects, including Tenebrio molitor, are considered sustainable and nutritious food sources that can help meet this challenge. This study focuses on improving the fatty acid profile and nutritional value of T. molitor larvae by using fish discard-based diets. Results show that pre-treatment of the diets can change the growth and composition of the larvae, with a fish-based diet leading to better results.

Summary: Investigated the use of larger and more T90 meshes in an Australian fish-trawl codend to improve size selection and reduce discards of deepwater flathead. Larger-meshed codends caught fewer immature flathead but lost some larger fish. The discard percentage in this fishery is likely to remain high (>75%), and efforts to improve selection should consider other modifications besides codend changes.

Summary: This paper introduces two algorithms that can invert simulated gravity data to 3D subsurface rock/flow properties. The first algorithm is a data-driven, deep learning (DL)-based approach, while the second algorithm is also data-driven but considers the temporal evolution of surface gravity events. The target application of these algorithms is the prediction of subsurface CO2 plumes for monitoring CO2 sequestration deployments. Both algorithms outperform traditional inversion methods, producing high-resolution 3D subsurface reconstructions in near real-time. Additionally, the proposed methods achieve high scores for predicted plume geometry and data misfit, indicating the effectiveness of combining 4D surface gravity monitoring with DL techniques for monitoring CO2 storage sites.

Summary: The increasing global demand for seafood products has led to more complex supply chains and challenges in tracing their origin and ensuring legal, sustainable sources. DNA-based methods can verify seafood authenticity at the species level, while verifying geographic origin remains more complex. Both genetic and stable isotope analyses have been used to determine point-of-origin with varying degrees of success, but selecting the right tool for each application is crucial. Ongoing research is needed to improve the application of these techniques for seafood point-of-origin validation.

Summary: Wild capture can be stressful for fish, and it is important to develop quantifiable and rapidly responsive biological indicators of stress. This study found that Atlantic mackerel exhibit a skin colour change from green to blue when exposed to crowding stress. The magnitude of this colour change was correlated to the severity and duration of crowding, suggesting that skin colour change could be a useful real-time indicator of crowding stress.

Summary: The impacts of wild capture fishing on animal welfare are poorly understood. This study focused on the welfare of Atlantic mackerel during purse seine fishing and found that crowding during pumping negatively affects their vitality. Larger catches and longer crowding exposure times have a greater negative impact. Blood lactate levels were negatively correlated with vitality, indicating that high-intensity anaerobic activity affected welfare. Targeting smaller schools could improve catch welfare by reducing crowding exposure times.

Summary: This study focuses on two commercially important gadoid species, the common ling and the blue ling, which have overlapping geographical distribution but different depth habitats. Genotyping-by-sequencing analysis revealed genetic differentiation in both species, with two major groups identified for each species. Fine-scale genetic structure was found along the coast of Norway for the common ling, while the blue ling showed stronger signals of differentiation related to adaptation to different depth habitats and cold temperatures.

Summary: The recent proliferation of pelagic Sargassum spp. in the Tropical Atlantic has caused significant ecological and socioeconomic impacts in the wider Caribbean region. The source of the Sargassum has been traced to a new bloom region called the North Equatorial Recirculation Region (NERR) located between the South Equatorial Current and the North Equatorial Counter Current. The study investigates the species and morphotype composition of Sargassum strandings in Barbados and identifies two distinct easterly sub-origins and/or transport pathways that contribute to the seasonal variation in morphotype abundance.
