Summary: This study applied the Rapid Vulnerability Assessment (RVA) to the sardine fishery in northwestern Mexico and found that RVA is a useful and flexible method for assessing vulnerability to climate change and can serve as a strategic planning tool. The study also found that RVA promotes co-management practices and identified the sardine fishery in the Gulf of California as the most vulnerable to climate change.

Summary: The abundance of adult fish depends on the survival of early life stages, which are influenced by mesoscale events in the marine environment. This study investigated the relationship between different mesoscale processes and the catches of Pacific sardine in the Gulf of California. The results showed that eddies and coastal upwelling had significant effects on the catches, while the persistence of Tropical surface sea water intrusion also played a role. The findings highlight the importance of considering these processes in climate change scenarios to understand their impact on trophic dynamics in the Gulf of California.

Summary: In this study, both single-algorithm and ensemble distribution models were established to predict the habitat distribution of Pacific sardine using environmental variables in the Northwest Pacific Ocean. The results showed that sea surface height and temperature were the key factors influencing the habitat distribution. The suitable habitat area for Pacific sardine varied monthly, with a counterclockwise pattern in the geometric centers of habitat suitability index.

Summary: The study reviewed the diet of predators before and after the collapse of the sardine population in the northern Benguela Upwelling System. It found that multiple predators relied on sardine as a high-quality food source. While the diets of commercially exploited species were well-documented, there was a lack of data for non-commercially exploited species.

Summary: Knowledge of the population dynamics and changes in abundance of Pacific sardine fishery is important for fishery management. This study used an integrated catch-at-age model to analyze 47 fishing seasons of Sardinops sagax in the Gulf of California. The model showed the importance of recruits in the fishery and highlighted the changes in abundance using spawning and acoustic indices. The Pacific sardine fishery in the Gulf of California has been fully exploited with a stable level of harvest.

Summary: Understanding the population dynamics and abundance variations of the Pacific sardine is crucial for effective fishing management. Through statistical analysis, it was found that there are different stocks of Sardinops sagax in the southern California Current System. The total biomass and spawning biomass of the sardine showed significant interannual variability, but overall, fishing was found to be sustainable during the analyzed period, except for the 2014 and 2017 fishing seasons. The use of an integrated analysis model (ACE) can estimate the biologically acceptable catch and a biomass-based harvest control rule is considered a suitable management strategy.

Summary: This study assessed the maximum sustainable yield (MSY) and stock resource status of Japanese sardine using historical catch data and biological data. The results indicate a healthy and recovering resource status. The study also proposed management strategies for the species, suggesting setting specific target ranges for the medium and long term. The findings suggest that Japanese sardine fishery resource can be sustainably used on a longer time scale.

Summary: A simulation was conducted to project the changes in fishery landings of the northern subpopulation of Pacific sardine, showing a northward shift in landings with declines at southern ports and increases or stability at northern ports. However, total sardine landings were found to be uncertain. The study also identified key constraints on future landings that can be targeted for further assessment.

Summary: The study shows that North Pacific oceanic variability plays an important role in precipitation changes over the U.S. West Coast, with stronger (weaker) precipitation anomalies during warm (cold) phases. These anomalies are particularly pronounced in Northern and Central California during winters and in Baja California during summers. The changes in precipitation are primarily modulated by alterations in water vapor flux, which are directed towards (away from) the coast in winters (summers). These flux anomalies are mainly driven by large-scale wind changes associated with the atmospheric response to strong ocean surface temperature anomalies.

Summary: Japanese sardine is an important small pelagic fish in the marine ecosystem of the far Eastern Asian waters. Fishing mainly uses purse seines, with catches showing varying trends over the past five decades. Research has focused on spawning migration, distribution, and biology, highlighting the need for further studies to improve conservation efforts.

Summary: The newly described deep-sea snailfish, Osteodiscus abyssicola sp. nov., found off the Pacific coast of Hokkaido, northern Japan, stands out from its congeners with distinct characteristics such as vertebral count, fin ray numbers, and mouth structure. This unique species is further distinguished by specific measurements and is accompanied by an amended diagnosis and key for species identification within the Osteodiscus genus.

Summary: Physiological traits of five key fish species from the northern Benguela upwelling system (NBUS) were compared during their larval stage. Results showed that pelagic goby and Cape horse mackerel had higher oxygen debt recovery capacity and hypoxia tolerance, which may explain their dominance in the NBUS.

Summary: This study presents evidence from the Jingtoushan site in West Pacific, indicating that maritime adaptation dates back to 8000 cal yr BP. The site was an anthropogenic deposit accumulated during the stable sea-level period and subsequently submerged by sea-level jumps. This study sheds new light on the understanding of the West Pacific coastal environment and cultural succession.
