Fish specimens were collected across the East China Sea (ECS) and Sea of Japan (JS), and isotopic data were retrieved from two previous studies. Six subareas were considered: the southern, central, and northern ECS; Tsushima Strait; and eastern and western JS. The residuals of isotope ratios predicted from fork length showed significant geographical variation in the ratios (a lower δ<sup>13</sup>C in the JS than in the ECS and Tsushima Strait; a lower δ<sup>15</sup>N in the eastern JS and southern ECS than in other areas). Comparisons of stable isotope ratios between jack mackerel and prey candidates also revealed geographical differences in potential prey selection. The potential prey was identified as anchovy larvae and larger Copepoda in the western and eastern JS, respectively, whereas various prey species contributed to the diet in the other areas. Both δ<sup>13</sup>C and δ<sup>15</sup>N increased with fork length, suggesting ontogenetic changes in foraging habitat, associated with habit shifts into demersal layers of jack mackerel during their growth.

Motivated by this, we investigate the potential for eggs and larvae of cod to stay behind at Jan Mayen after spawning, which would be a requirement for having a self-sustained stock. This is done using a numerical model for larval drift and growth, similarly to what has been done for other cod stocks. Using the modelled drift, we compare the proportion of larvae retained in different years to the strength of year classes as indicated by fisheries data. We find that even if most individuals are transported away from Jan Mayen, there are still some years where a significant proportion (more than 20%) of the larvae remains at the time of settlement in October–November. However, the year-to-year variability is large, with almost no individuals remaining in certain years. Our results suggest that aggregated over years, the amount of larvae that reach the age of bottom settlement on the Jan Mayen shelf area could be sufficient to give a potential for a self-sustained cod population.

Given recent climatic changes in the northern Antarctic Peninsula (NAP), the distribution of krill and salps are shifting poleward. Unlike krill, salps thrive in warmer water temperatures and can form large blooms under favorable conditions, potentially outcompeting krill for resources. However, krill are ecologically more important, serving as a primary food source for higher trophic levels. The interspecific interactions, including hotspots and ecological niches, of krill and salps in the NAP were therefore investigated using historical datasets and species distribution models. We found that both spatial separation and overlap occurred between krill and salps hotspots, with the primary overlap occurring around Elephant Island. Furthermore, there was a significant overlap in their ecological niches, suggesting that they may have similar ecological requirements.
