“…From this two-level slicing method, the bright areas thought to be caused by the fishing fleet were extracted. It is assumed that the squid were caught in the areas where fishing vessels were located [2,3]. The earlier work by Choi et al [3] revealed that DMSP/OLS-inferred squid fishing locations in the southwestern part of the Sea Figure 1.…”

“…In Japan, the Japanese common squid catch constitutes roughly 56% of the total cephalopod catch. It is also one of the large-scale fishery resources commercially harvested by Korea [3] and China [4]. Moreover, T. pacificus is on the top two or three in total annual landings of cephalopods in the world and is the largest single cephalopod fishery resource, over time, on record [5,6].…”

Seasonal Habitat Patterns of Japanese Common Squid (Todarodes Pacificus) Inferred from Satellite-Based Species Distribution Models

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.

“…Previous studies on the temporal analysis of fishing conditions for common squid were mostly based on long-term oceanic conditions and catch data and those on the spatial distributions of the fishing grounds for common squid focused on monthly variabilities of the fishing grounds (Kiyofuji et al, 2001;Kim, 2002;Cho et al, 2004;Choi et al, 2008 …”

In this study, we estimate the interannual spatial and temporal distributions of fishing grounds at night in the East Sea based on satellite and in-situ data. We observe that the 15℃ thermal front moves in the north-south direction according to the movement of the warm water (above 18℃) in the Tsushima Warm Current (TWC) area, forcing the cold water area (below 10℃) to either expand or shrink. The interannual variations of sea surface temperature (SST) in winter represented by the indicator SST of 6℃ are consistent with the east-west zonal areas in the central East Sea which represented over 1℃ standard deviation of SST in February during 1990-2000. Annual SST in the fishing grounds of common squid fishing vessels, observed both by fishing vessels and satellites range from 9-22℃, with the satellite-observed data having a larger range than the fishing vessel-based ones. The interannual distributions of the common squid fishing grounds in the East Sea are mostly concentrated in the TWC area in the southwestern part of the East Sea and in the coast of southern Honshu and Hokkaido in Japan. The interannual distributions of the nighttime fishing vessels are consistent with the catches investigated from the fishing vessel.
