Summary: The study focused on the Norway lobster fishery in Pagasitikos Gulf, finding that the local stock is over-exploited. Long-term monitoring of population dynamics, fishery, and exploitation status are crucial for sustainable management of this valuable shellfish resource. Regional policymakers should take into consideration the findings when making decisions.

Summary: Maine's coastal communities rely heavily on the American lobster fishery, but it is now facing the threat of ocean warming, leading to uncertainty in the stock's future robustness and the fleet's economic performance. This research examines the economic heterogeneity of Maine's fishing fleet and explores the diversity of business models and their association with fleet's economic performance before the warming period. The findings suggest that economic efficiencies differ based on the chosen business models, and technical upgrades generally lead to improved economic performance. The study establishes a crucial baseline for future policy reforms in the US lobster fishery.

Summary: Maine's coastal communities heavily rely on the American lobster fishery, but it is now threatened by ocean warming. The future sustainability of the stock is uncertain, and the economic performance of the fishing fleet is at risk. This research analyzes the economic heterogeneity within Maine's fishing fleet and explores how different business models are associated with fleet performance. The findings suggest that technical upgrades can improve economic performance, but societal benefits and employment levels have also shaped the lobster production environment. This study provides a crucial baseline for future policy reforms in the US lobster fishery.

Summary: Crustaceans, crucial for food security worldwide, are highly vulnerable to climate change. However, the impact of regulatory strategies on the climate-driven life history change has been seldom evaluated. This study compares the performance of different minimum legal size regulations for American lobster, and shows that increasing the minimum legal size can improve fishery output.

Summary: Lobsters are a crucial component of Fiji's small-scale fisheries, but there is a lack of data. Through seafood value chain analysis, this study provides insights on the different actors involved in the fishery and reveals human-wildlife interactions that may not otherwise be known. The study also highlights the importance of length-based spawning potential ratios and size at maturity thresholds in data-poor small-scale fisheries.

Summary: The Dosidicus gigas (jumbo flying squid) is highly sensitive to climate variability and marine environment changes, which have significant impacts on its population structure and development. La Nina events benefit individual growth and delay sexual maturity, while El Nino events inhibit growth and accelerate sexual maturity of the D. gigas.

Summary: The study found that considering spatial nonstationarity in the Gulf of Maine can lead to improved distribution estimates for the American lobster. The finest-scale model performed best, with larger-scale models tending to overestimate lobster abundances in the western portion of the Gulf, underestimate in the western portion of the central Gulf, and overestimate in the eastern portion of the central Gulf.

Summary: This study used a global storm resolving model to simulate the changes in the frequency of intense convection under different sea surface temperature conditions. The results showed that increased sea surface temperature globally enhanced the frequency of intense convection, but with significant spatial and seasonal variations. Changes in the spatial pattern of intense convection were associated with changes in planetary circulation.

Summary: This study explored the effects of climate change on the reproductive activity of the monsoon river prawn in the Ganges River basin of Bangladesh. The study found a significant correlation between rainfall and the spawning season, with rainfall impacting the number of ovigerous females and fecundity. The findings suggest that the spawning season of the monsoon river prawn may shift due to climate change.

Summary: Climate change is causing unprecedented warming in marine environments. Crustaceans show strong responses to rising temperatures, including smaller molt increments, more frequent molting, and decreased size-at-maturity. However, research quantifying the potential impacts on population and fisheries dynamics is limited, despite the increasing importance of crustacean fisheries globally.

Summary: Ocean acidification has varying impacts on lobster populations, with the largest effects seen in juvenile stages. Managing fishing pressure and size limits can help mitigate some negative effects of OA, but the overall impact of climate change overshadows these population gains. Addressing greenhouse gas emissions is crucial for long-term population resilience.

Summary: Many marine species are shifting their distributions in response to changing ocean conditions, which poses challenges for fisheries management. Species distribution models (SDMs) are used to project future distributions, but there is concern that fishery-dependent data may bias predictions. Understanding the strengths and limitations of SDMs based on fishery-dependent data is critical due to limited resources for fishery-independent surveys.

Summary: This data collation presents research data on seagrass from 1975 to 2020, including biotic and abiotic habitat characteristics. The study found that biomass and structure of seagrass are important aspects, while data on production are limited. These data can be utilized in seagrass ecology and other related research fields.

Summary: Global warming influences Earth's cloud cover, which plays a crucial role in the uncertainty of Equilibrium Climate Sensitivity (ECS). Through analyzing how clouds respond to environmental changes, global cloud feedback is constrained to 0.43 +/- 0.35 W·m-2·K-1, indicating a robust amplifying effect of clouds on global warming. This approach is expected to provide tighter constraints on climate change projections and its various socioeconomic and ecological impacts.

Summary: Anthropogenic carbon emissions are causing rapid increases in temperature and acidity in oceans worldwide. This study evaluates the effects of warming and acidification on gene expression in postlarval American lobsters and found that gene regulation is more responsive to elevated pCO(2) than to temperature changes. The combined effect of both stressors significantly impacts gene regulation in lobster larvae, indicating their ability to respond to a changing environment.

Summary: The size at maturity of female lobsters in the Gulf of Maine has decreased over the past 25 years due to a observed inverse relationship between temperature and maturity size. By using ovarian staging and growth measurements, researchers were able to accurately assess lobster stocks and their reproductive development.

Summary: Fishery-independent ventless trap surveys play a crucial role in assessing American lobster population trends, with factors like soak time, day of year, and unique site affecting catch variability. Model-based abundance indices show similar trends to traditional design-based approaches, with slight differences in magnitude and trends observed in different regions.
