Summary: The distribution and fishing grounds of Pacific saury are significantly influenced by oceanographic factors, with sea surface temperature being the most important factor. The intrusion area of the Oyashio has a synchronous trend with the migration of Pacific saury to the Japanese coastal region. This study extends our understanding of the effects of oceanographic environment on Pacific saury.

Summary: The development of appropriate environmental predictors is crucial for improving fish habitat models. This study introduces a new predictor representing mesoscale oceanographic features (MOFs) and reassesses the role of MOFs in fish distribution. The results show that the new predictor significantly improves the performance of commonly used fish habitat models and highlights the importance of MOFs in Pacific saury distribution.

Summary: In this study, a habitat suitability index (HSI) model based on multiscale habitat features was developed to assess the distribution and fragmentation degree of the suitable habitat for Siberian cranes in Poyang Lake. Results indicated that the HSI model could effectively recognize the potentially suitable habitats and the impact of a proposed hydraulic project on suitable habitat. The study provided a quantitative method to evaluate suitable habitats for Siberian cranes and could serve as a reference for water level management of the proposed project.

Summary: The habitat preferences and range of the endangered Francois' langur were surveyed in the Mayanghe Nature Reserve, Guizhou, China. Gaussian normal kernel density estimation and species distribution models were used to estimate the langur's range and predict suitable habitat. The research found that the langur mainly inhabits broad leaf forests in lower elevations near rivers, and the suitable habitat in the reserve accounts for 20.08% of the total area.

Summary: This study utilized a neural network model to evaluate three commonly used AI proxies at different spatial scales, finding that AI based on catch data outperformed CPUE and effort-dependent Al models in terms of accuracy, consistency, and spatial representational ability. Results from the 0.5 degrees x 0.5 degrees resolution model preserved enough distributional detail to reflect the known migration route for O. bartramii.

Summary: Understanding the spatial distribution of fishing activity and suitable fishing areas is crucial for sustainable fisheries management. This study developed habitat suitability index models using marine environmental data to identify climate-related habitat changes and variations in the distribution of fishing activity for squid-jigging vessels in the Northwest Pacific Ocean. The results showed significant seasonal changes in suitable fishing areas, and the weighted arithmetic mean method performed better in predicting fishing activity. The study emphasizes the importance of managing high fishing pressure areas and acknowledges the limitations of fishery data.

Summary: Aquatic ecosystems are crucial for the global environment and play a critical role in hydrogeological processes in rivers. Climate change-induced hydrological flow regime alterations have significant impacts on habitat suitability for aquatic species. A study in the Kulsi river, India, found a strong association between the decline in endangered Gangetic dolphin populations and reduced habitat suitability. Proposed river development projects in upstream regions could pose a serious threat to dolphin communities by altering flow patterns. The findings of this study can inform conservation action plans and flow regulation strategies to ensure the long-term survival of endangered species.

Summary: The aim of this study was to predict the distribution of smallmouth bass, a potential invasive alien species, in South Korea using a habitat suitability model based on life history. Environmental data from 160 sites across five river basins were collected to conduct present and future predictions. The model considered different spawning scenarios and evaluated the life-history habitat suitability of smallmouth bass. The results suggest that urgent preventive measures are needed as the distribution of smallmouth bass may expand under global warming.

Summary: Satellite data is increasingly used in agriculture for estimating biomass, nitrogen content or crop yield. Users need to select appropriate data for specific problems to avoid economic risks. High correlation values between yield data and satellite data are found, especially with spatially heterogeneous fields and correct phenological timing.

Summary: An ecological water supplement project (EWSP) can change river hydrological processes and potentially affect the habitat suitability of aquatic organisms. This study used a simulation framework to assess the impact of EWSP on the habitat suitability of a high-leakage river in China. Results showed that neglecting river leakage could lead to an overestimation of fish habitat suitability. The impacts of EWSP on habitats varied with different factors, such as topography, geology, water supplement season, discharge magnitude, and duration. The optimal water supplement discharge for the river was found to be 15-25 m3/s.

Summary: Grassland locusts cause significant harm to grasslands every year and greatly impact the lives of herdsmen. The monitoring and identification of locust habitats are crucial for the efficient utilization of grassland resources. Previous methods for identifying suitable habitat areas have resulted in oversized results, hindering precise control of grassland locusts. However, our study utilizing hierarchical prediction and a maximum entropy model showed promising results in categorizing habitat-suitability areas based on locust density thresholds, providing a basis for efficient and accurate control of grassland locusts.

Summary: This study reveals the evolution of habitat distribution for multiple fish species in the lower reaches of the Gongzui Hydropower Station. The results indicate that the model can effectively evaluate the distribution of multiple fish habitats, with a decrease in suitable habitat area and connectivity as discharge increases. The habitat also shifts downstream.

Summary: This study evaluates the impact of considering ageing error and growth variability on the determination of input sample size (ISS) in statistical catch-at-age assessment models. The results show that including these sources of uncertainty decreases the ISS determined through bootstrap methods. This indicates that there is more variability in age composition and conditional age-at-length data than previously accounted for. Including these sources of uncertainty improves the estimation of ISS and subsequently improves the quality of stock assessment models.

Summary: Recent advances in genomics have greatly contributed to the assessment of fish stocks by providing precise identification of genetic boundaries. This study used a genotyping-by-sequencing approach to reveal the existence of an additional genetic cluster of blackspot seabream in the northeast Atlantic, which was not previously identified. Factors such as ocean circulation patterns and local upwelling may play a role in the genetic differentiation observed in this study.

Summary: Estimating growth is important for fish population assessment. Integrated assessment models and the influence of misfitting size composition data have renewed interest in how growth is modeled. The available data types control how the length-at-age relationship is estimated. Estimating length-at-age is complex due to multiple sources of biological variability and difficulties in obtaining representative samples.

Summary: Small-scale fisheries are vital for global food security and cultural heritage, but the lack of information hampers effective management and mitigation of ecological impacts. This study provides the first comprehensive overview of the small-scale fishery fleet in Northern Cyprus. The fleet operates mainly over the continental shelf, using static and demersal gear types, and catches a diverse range of species, some of which are threatened. The findings can be used to improve fisheries management and conservation measures.
