“…To date, various methods have been used to estimate spawning grounds. Catch-per-unit-effort (CPUE) analysis is often performed as a fishery-dependent method to investigate the distribution characteristics of target fish during the spawning period (e.g., Tomiyama et al, 2021) along with a survey of the gonadal conditions to confirm the presence of ovulated eggs or postovulatory follicles. However, the greater amberjack in the ECS has not been the subject of stock surveys in any countries that consume the species, and there are no CPUE data.…”

Greater amberjack (Seriola dumerili) is an important fishery resource with a circumglobal distribution from tropical to temperate waters. Here, we investigated the spawning migration and habitat utilization of S. dumerili in the East China Sea (ECS). Archival tags were attached to 22 adult fish to examine their horizontal and vertical movements and estimate the spawning ground. S. dumerili were captured and released in the coastal waters of eastern Taiwan on November of 2016 and 2017.Information from seven pop-up satellite archival tags and seven depth-temperature recorders was recovered. Almost all of the fish stayed in the Taiwanese exclusive economic zone. Most individuals moved from released site to the southern edge of the ECS and showed behavior associated with the topographic features in winter (November to December). These phenomena may be related to foraging and be driven by oceanographic features such as the seasonal monsoon and the Kuroshio.The fish then migrated to the south offshore area of Taiwan in January and February.During their southward migration, the fish experienced a slowly elevated water temperature regime (SETR), which is one of the environmental factors that induce final oocyte maturation. In the spawning season (February to April), tagged females exhibited continuous diel vertical movements (DVMs) after experiencing the SETR. These continuous DVMs were observed over a wide geographic range from north to south in the Kuroshio off eastern Taiwan. Our study demonstrated that the putative spawning ground of S. dumerili must extend further in a north-south direction than predicted in a previous study.

“…Several studies report that members of the genus Pseudopleuronectes, including the marbled flounder, tend to move to cooler and deeper bay areas to avoid high water temperatures in summer (Ishii 1992;Kume et al 2006;DeCelles and Cadrin 2010;Sagarese and Frisk 2011;Able and Fodrie 2015;Tomiyama et al 2021). Consequently, the tagged marbled flounders in this study were expected to move to either of the two straits with deeper and, therefore, potentially cooler waters.…”

“…The marbled flounder is an important fishery resource and is distributed in temperate coastal waters of the Northwest Pacific Ocean. Fishery data and investigations using trawl have demonstrated that, after spawning in shallow waters in winter, adults likely move to deeper waters with more suitable temperature and DO conditions in the summer to avoid high temperatures (> 20 °C) and hypoxia (Ishii 1992;Kume et al 2006;Hibino et al 2015;Tomiyama et al 2021). In a recent study, we showed that some marbled flounder individuals remain in shallow water (< 30 m) over summer in a bay with water temperatures of 19-23 °C, and this behavior may be linked to food availability in the shallows (Mitamura et al 2020).…”

spatial reference (landmarks for their navigation), or as meeting points. However, little is known about the impact of artificial reefs on the migratory behavior of demersal flatfish. The marbled flounder (Pseudopleuronectes yokohamae), an important commercial flatfish species, exhibits seasonal migration between shallow water for spawning in winter and deeper water to avoid high water temperatures in summer. In this study, 39 tagged marbled flounders were released in the shallow water of the inner Osaka Bay area in Abstract Offshore manmade structures, termed artificial reefs (e.g., wind farms, oil platforms, and manmade islands), affect the movement and migration of wild migratory marine animals. Certain types of migratory pelagic and benthic fish are known to utilize artificial reefs as feeding areas, for

“…Hatchery-reared juveniles have been released in Japanese waters at sizes ≥20 mm SL (Howell and Yamashita, 2005). This species spawns mainly in December-January (Tomiyama et al, 2021), and juveniles appear in the shallow area in March-May (Joh et al, 2009;Hata et al, 2016). It has been reported that hatchery-reared juveniles of 21 mm SL achieve maximum growth at ambient temperatures of 12-14 °C, whereas those of 31-47 mm SL show maximum growth at 20 °C (Kusakabe et al, 2017;Tomiyama et al, 2018).…”
