“…This is in agreement with the observations of Syah et al. () in which the potential fishing zones patterns were explained predominantly by SST. On the other hand, the frontal structures and eddy fields may play an important role in the development of potential Pacific saury habitats by creating hydrodynamic trap of prey and stimulating feeding conditions (Tseng et al., ; Yasuda & Watanabe, ).…”

“…The environmental variables used in the models are key predictors for Pacific saury habitats, as demonstrated by laboratory experiments (Oozeki & Watanabe, ), analyses of survey data (Oozeki, Takasuka, Okamura, Kubota, & Kimura, ; Oozeki, Watanabe, & Kitagawa, ; Ueno et al., ), and fishery‐dependent data (Kuroda & Yokouchi, ; Syah et al., ; Tseng et al., ). We fitted significant nonlinear relationships between the Pacific saury catches and the environmental variables (Figure ).…”

“…For example, an empirical cumulative distribution function approach identified that high CPUE of Pacific saury occurred when SST ranged from 14 to 16°C and NPP ranged from 600 to 800 mg carbon m −2 day −1 in the same studied area (Tseng et al., ). Oceanographic conditions on the formation of potential fishing zones for the Japanese fishing vessels in the waters off the Kuril Islands and east of Hokkaido were found in the range of 14–16°C (Syah et al., ). In addition, there were high probabilities of occurrence of Pacific saury at positive SSH anomaly values.…”

“…Catch and fishing effort have been considered an index of fish occurrence or the Pacific saury availability by Tian et al. (, ) and Syah, Saitoh, Alabia, and Hirawake (), respectively. In this study, we analysed catch, rather than CPUE, in relation to each of above four environmental variables to identify the suitability index of the Pacific saury.…”

We developed habitat suitability index (HSI) models for two size classes of Pacific saury Cololabis saira in the Northwestern Pacific Ocean. Environmental data, including sea surface temperature, sea surface height, salinity, and net primary production, and catch and effort data from Taiwanese distant‐water stick‐held dip net fisheries during the main fishing season (August–October) during 2002–2015 were used. Habitat preferences and suitable habitat area differed between size classes. The suitable habitat was located between 40–47.5°N and 145–165°E for large‐sized Pacific saury but encompassed a greater area (35–47°N and 140–165°E) for medium‐sized Pacific saury. Both size classes were affected by substantial interannual variation in the environmental variables, which in turn can be important in determining the potential fishing grounds. We found a significant negative relationship between the suitable habitat area and the Niño3.4 indices with a time‐lag of 6 months for the large‐sized (r = −0.68) and medium‐sized (r = −0.42) Pacific saury, respectively, as well as the total landings of Pacific saury by all fishing fleets (r = −0.46). As remotely‐sensed environmental data become increasingly available, HSI models may prove useful for evaluation of possible changes in habitat suitability resulting from climate change or other environmental phenomena and in formulating scientific advice for management.

“…Therefore, tapping alternative data sources to further fisheries studies has attracted fisheries scientists and managers. The night-time visible imageries have been earlier used in a variety of marine applications, including that for tracking ship and fishing activities [2,3,37,38]. Our study further expanded the practical applications of these data to examine the squid-environment interactions through a habitat modeling approach.…”

Abstract:The understanding of the spatio-temporal distributions of the species habitat in the marine environment is central to effectual resource management and conservation. Here, we examined the potential habitat distributions of Japanese common squid (Todarodes pacificus) in the Sea of Japan during a four-year period. The seasonal patterns of preferential habitat were inferred from species distribution models, built using squid occurrences detected from night-time visible images and remotely-sensed environmental factors. The predicted squid habitat (i.e., areas with high habitat suitability) revealed strong seasonal variability, characterized by a reduction of potential habitat, confined off of the southern part of the basin during the winter-spring period (December-May). Apparent expansion of preferential habitat occurred during summer-autumn months (June-November), concurrent with the formation of highly suitable habitat patches in certain regions of the Sea of Japan. These habitat distribution patterns were in response to changes in oceanographic conditions and synchronous with seasonal migration of squid. Moreover, the most important variables regulating the spatio-temporal patterns of suitable habitat were sea surface temperature, depth, sea surface height anomaly, and eddy kinetic energy. These variables could affect the habitat distributions through their impacts on growth and survival of squid, local nutrient transport, and the availability of favorable spawning and feeding grounds.
