Summary: The krill Nyctiphanes australis is the most abundant and ecologically important euphausiid in southern Australia and New Zealand coastal and shelf waters. The species lives in coastal environments which are currently susceptible to shifts in temperature and productivity. The study used Dynamic Energy Budget models (DEB) to analyze the temperature and food dependency of growth and reproduction of Nyctiphanes species. The results show that higher temperatures and low food levels may decrease the energetic content and diameter of the eggs, potentially leading to a decline in N. australis populations and affecting coastal marine ecosystems and inshore fisheries.

Summary: The Barents Sea is experiencing rapid ocean warming, decreased sea ice, and increased Atlantic inflow, leading to a transition towards a more temperate pelagic ecosystem. The extent of this Atlantification process in the northern Barents Sea and Arctic Ocean is not well understood. In this study, the biodiversity, abundance, and biomass of mesozooplankton were examined along a transect in the Northern Barents Sea. Different biogeographic regions and distinct communities of mesozooplankton were identified, with variations in species composition and seasonal dynamics.

Summary: Copepods, as a dominant component in marine food webs, are facing potential biogeographical range shifts and phenological changes due to climate change and rising sea surface temperatures, which can greatly impact the whole food-chain. The analysis of a recent copepod time series from the Belgian Part of the North Sea revealed significant discrepancies in phenology, abundances, and total biomass between nearshore and offshore regions, with anomalies detected in abundance and biomass in certain years, likely influenced by heat waves and other environmental factors. This study emphasizes the importance of long-term copepod data series in understanding the effects of climate change on marine ecosystems.

Summary: Phenotypic plasticity and evolutionary adaptation can help populations cope with global change, but the limits and costs of adaptation under multiple stressors are not well understood. This study found that a copepod species, Acartia hudsonica, initially experienced a decline in fitness under the combined effects of ocean warming and acidification, but fully recovered within four generations, indicating an adaptive response and synergy between stressors. However, in the long term, the fitness of the adapted lineage was lower compared to the ambient conditions, suggesting a cost to producing phenotypes adapted to both warming and acidification. The study also found sustained phenotypic plasticity in the adapted lineage, even when exposed to different environments.

Summary: Climate change is expected to directly impact fishery production by influencing marine biota and ecosystems. To respond to this challenge, assessing vulnerability to climate change is crucial. In South Korea, changes in species composition and ecological structure caused by climate change have led to a decline in annual fishery production since 1986. In this study, vulnerability to climate change was evaluated for 36 species based on sensitivity and exposure, and the vulnerability of 24 fisheries was assessed. Priority should be given to fisheries with a high catch ratio of relatively vulnerable species when formulating policies to manage offshore and coastal fisheries in Korea.

Summary: Current coral reef future models rely on threshold (TM) and multivariate environmental variability models (VM), with VM based on General Additive Model showing more accurate predictions for coral cover by considering significant environmental and fisheries management variables and determining that common predictive variables are weak or not significant predictors of coral cover. By comparing the predictions of the two models for future coral cover, it was found that the VM is more accurate than the TM in predicting coral cover in 2050.

Summary: Species redistributions due to climate change are observed globally in oceans. Predicting temperature-driven changes in species interactions and their effects on marine communities is challenging. In southeast Australia, where ocean warming is prominent, the range of eastern rock lobster has expanded into warming Tasmanian waters, leading to potential increased competition with the resident southern rock lobster. This study found that the resident lobster not only dominated in food competition but also maintained its competitive advantage under future ocean warming and heatwave scenarios.

Summary: Marine recreational fishing in Norway faces challenges in estimating catches due to its long coastline and large tourist fishery. This study conducted surveys to monitor recreational anglers, estimate their catches, and evaluate the fishery in Troms and Hordaland County. The results showed differences in catches between the two regions and revealed that recreational anglers in Hordaland harvest more cod in coastal waters than commercial fishers. This study provides valuable information for developing monitoring methods and supporting science-based fisheries management.

Summary: Ocean and climate drivers have a global impact on the distribution and abundance of marine life. Marine ecological forecasting aims to predict how living marine resources respond to physical changes, facilitating proactive decision-making for climate adaptation. However, the accuracy of ecological forecasts is limited by the quality of models for ocean state and species-environment relationships. To assess the accuracy of data-driven forecasts for fisheries, predictive models were developed using catch data and climate reanalysis for tuna and billfish in the southwest Pacific Ocean. Descriptors of water column structure, particularly temperature at depth and upper ocean heat content, were found to be useful predictors of catch-per-unit-effort (CPUE) for these species. Improving forecast accuracy over sub-seasonal to multi-year timescales may require the incorporation of sub-surface ocean data and consideration of regional physical dynamics.

Summary: Recreational fishing is undervalued and poorly integrated into the management of multi-sector fisheries, leading to marginalization of recreational fishers and hindering fisheries sustainability. A study on marine fisheries harvest strategies in 11 nations reveals a gap in inclusion of recreational fishing compared to the commercial sector. The lack of explicit objectives, data collection, performance indicators, and management controls in harvest strategies for recreational fishing reduces its effectiveness in achieving sustainability goals.
