Summary: This study analyzes the spatial variation in the distribution of fishing activity and the change of fishing ground gravity for neon flying squid using AIS data. The results show a positive correlation between latitudinal fishing ground gravity and Kuroshio Extension indicators based on high-frequency EKE. Furthermore, the Kuroshio Extension indicators have a positive relationship with the number of eddies generated in the fishing ground. This research highlights the importance of understanding the influence of eddies and the Kuroshio on the distribution of neon flying squid.

Summary: The study revealed differences in microstructural and chemical properties between neon flying squid (OB) and jumbo squid (DG) mantles after frozen storage. Jumbo squid showed better stability in myofibrillar protein (MP) content compared to neon flying squid. Label-free proteomic analysis identified various differentially abundant proteins (DAPs) in the mantles of both species, with some proteins improving the stability of jumbo squid in response to freezing-induced changes.

Summary: The neon flying squid, an economically important oceanic species, has been commercially harvested in the North Pacific by Japan, Korea, China, and Taiwan. A long-term research conducted by the Fisheries Research Agency of Japan from 1980 to 2009 collected data to understand the resource ecology of this species. A habitat map was created using a generalized additive model and ocean/sea ice reanalysis data, revealing a high abundance area at the Subarctic Frontal Zone (SAFZ) with increasing squid abundance from April to August. This research suggests that the SAFZ plays a crucial role in North Pacific ecosystems by providing optimal conditions for the neon flying squid in terms of temperature and food density.

Summary: This study evaluates the impact of mesoscale eddies on the abundance and habitat distribution of neon flying squid in the Northwest Pacific Ocean. The findings suggest that suitable thermal conditions and favorable foraging conditions within anticyclonic eddies are the main drivers of high squid abundance in warm eddies.

Summary: This study analyzed the migration route of Ommastrephes bartramii in the North Pacific Ocean using statolith microchemistry, revealing differences in element composition and concentration between different seasons. By applying Bayesian model and random forest method, the study predicted the optimal squid location and potential migration routes in the ocean.

Summary: This study analyzed the relationship between the spatial distribution of O. bartramii and deep-water temperatures by constructing generalized additive models (GAMs) using Chinese squid-jigging fishery data and Argo deep water temperature data. The results showed that surface water temperature, water temperature at different depths, and water temperature differences significantly affected the spatial distribution of O. bartramii. The predicted suitable habitat area and high-density area were also regulated by El Nino-Southern Oscillation (ENSO) events.

Summary: The physicochemical and volatile flavor properties of neon flying squid (OB), jumbo squid (DG), and Argentine squid (IA) mantles were studied during 8 days of chilled storage. The results showed that the chilled conditions caused rapid increases in pH value, TVBN, and carbonyl and MDA content of the squid mantles, while MP content decreased and springiness declined. OB mantles exhibited less chemical stability compared to the other two species. Histological observations revealed that DG mantle tissues had more compact structures. Volatile flavor analysis identified several compounds that were highly abundant in the mantles, likely due to protein and lipid decomposition, oxidation, and degradation, which varied among the different squid species. These findings provide insights into the quality changes of the three squid species during chilled storage.

Summary: The study examined the trophic ecology and spatial ecology of the neon flying squid in the North Pacific Ocean. The results showed that the diet and trophic level of the squid changed with ontogenetic growth. The trophic niche breadth increased from the paralarval to the juvenile stage and decreased from the juvenile to the subadult-adult stage. Interactions between different ecosystems led to a greater diversity of food sources for the squid.

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: Oceanic squids are sensitive to environmental changes. The study observed morphological variations in body and beak sizes of Ommastrephes bartramii in relation to different climate events. The size of individuals showed differences in maturity stage among different climatic years, and significant differences were found in beak sizes between two Pacific Decadal Oscillation phases.

Summary: The connection between the North Tropical Atlantic (NTA) sea surface temperature (SST) anomalies and El Nino-Southern Oscillation (ENSO) events varies considerably over multidecadal timescales and is mainly controlled by the multidecadal variability of the North Atlantic Oscillation (NAO). During the positive phase of the NAO, the NTA impact on ENSO is amplified due to strengthening of precipitation over the equatorial Atlantic and enhancement of the persistence of NTA SST anomalies.

Summary: This study suggests that the North Atlantic forcing plays a more significant role than the tropical Pacific forcing in the decadal prediction of sea surface temperature (SST) variability in the North Pacific. By removing the North Atlantic forcing, the prediction skill of NP SST decreases, indicating its strong contribution to the long-term prediction. The research emphasizes the need for improving the simulation of the Atlantic trans-basin effect for better predicting NP climate.

Summary: This study analyzed synchronous fluctuations in abundance and distribution of Ommastrephes bartramii in the Northwest Pacific Ocean and Dosidicus gigas in the Southeast Pacific Ocean during 2006-2015. The results suggested that synchronous changes in the two squid species were influenced by sea surface temperature anomaly, Niño indices, and the proportion of favorable-SST area in their respective fishing grounds.
