Summary: This study provides important ecological information on growth and age analysis of Chub mackerel in the northwest Pacific Ocean. The results indicate that Chub mackerel exhibits slower growth rate and relative condition factors vary among different years, seasons, and regions.

Summary: The prevalence of Kudoa thyrsites, a myxozoan parasite, in Atlantic mackerel in the Faroese waters was investigated in this study. The results showed that K. thyrsites was present in 98% of the examined mackerel samples, and there was a strong agreement between the microscope smear and qPCR techniques. The overall prevalence of K. thyrsites in the collected samples from 2017 and 2018 was 4.1%, with variations at different locations. The logistic regression model indicated that sampling location and month were associated with the odds of infection, while age, weight, and length showed no significant association. The study also found no molecular evidence of K. thyrsites spores in Faroese plankton assemblages, supporting the hypothesis that the alternating invertebrate host and mackerel infection occur in more southern waters.

Summary: This study evaluated the effects of different frying methods on the physiochemical and nutritional properties of mackerel, finding that vacuum frying is the best method with minimal oxidation and maintained nutrition. Vacuum frying had the lowest increase in VBN, TBARS, and pH, and significantly differed from the other methods, as well as resulting in increased amino acid and preserved fatty acid content. These findings could be applied in the fisheries industry to produce the best fried mackerel while preserving its high nutritive value.

Summary: In this study, the relationship between target strength (TS) and fork length in chub mackerel was evaluated. The results showed that TS tended to increase with fork length, and TS was influenced by swimming angle and speed.

Summary: This study used the KRM model to investigate the target strength (TS) of chub mackerel and its relationship with sound wave frequency and fish morphology. The results showed that TS varied with changes in pitch angle, with a greater impact at higher frequencies. The study also found that TS was highest within a specific pitch angle range at different frequencies. These findings can be used for the identification of chub mackerel in echograms and provide insights for acoustic stock assessment.

Summary: The combination of superheated steam roasting and hot smoking was applied to Chub mackerel fillets to extend shelf-life, improve sensory properties, physicochemical, microbial, and nutritional properties, and promote shelf life during storage. The processed CM offered high nutritional value and reduced trimethylamine-N-oxide level, indicating quality and safety with high nutritional standards.

Summary: This study aimed to develop a ready-to-heat Korean preparation of chub mackerel using vacuum frying technology, which was found to produce better sensory, chemical, and microbial properties compared to conventional deep frying. The nutritional values, including amino acid and fatty acid contents, were higher in vacuum frying. Sensory properties also showed better scores in appearance, aroma, taste, and overall acceptability.

Summary: In this study, standardized catch per unit effort (CPUE) data and marine remote sensing environmental data were integrated to construct CPUE standardization models for chub mackerel. The performance of the models was evaluated, and the spatio-temporal distribution patterns of chub mackerel in the Northwest Pacific Ocean (NPO) were analyzed. The results showed that the VAST model outperformed the GLMM model in CPUE standardization, and there were significant temporal and spatial variations in the distribution of chub mackerel.

Summary: This study characterized the spatiotemporal distribution of Pacific chub mackerel in the northern Peruvian Current System by analyzing ecological niche and projected future climate change effects. Models calibrated with sea surface temperature and salinity showed good performance, with predictions for El Nino and La Nina conditions. Future scenarios indicated potential changes in habitat suitability and climate refugia, highlighting the importance of considering extreme conditions in model calibration. More testing is needed to validate these findings.

Summary: The study revealed that the abundance of conspecifics and heterospecifics negatively impacts the body condition and growth of chub mackerel, with direct effects likely playing a more significant role than indirect effects.

Summary: This study aims to provide a wider choice of potential models for the stock assessment of Chub mackerel in the Northwest Pacific. The results indicate that the Chub mackerel stock may be slightly overfished, but could also be healthy. Further projection is required for specific catch limit setting. Management efforts should focus on maintaining or slightly reducing fishing effort and accurately estimating input parameters.

Summary: This study evaluated the stock status of chub mackerel in the Northwest Pacific Ocean. Previous assessments mainly relied on catch data from one country, but this study used total catch data from multiple countries. Using a catch and maximum sustainable yield model, the results showed that the current chub mackerel biomass is lower than the required level for maximum sustainable yield. Sensitivity analysis also confirmed these findings. Improved cooperative resource management is needed to prevent further decline.
