“…In this study, T. gaudichaudii showed a negative relationship with temperature and salinity. In northern Yellow Sea, C. abdominalis was relatively higher in the cold waters and occurred in the northern part of Yellow Sea (Kang et al, 2008). This species was found in cold-neritic seas (Jang et al, 2012).…”

Aim:Methodology: Results:Interpretation: Key words:Zooplankton are distributed by hydrographic factors such as temperature and salinity. The research aims to investigate the distribution patterns of zooplankton and indicator species of water bodies, and to understand the relationship between zooplankton distribution and water bodies in Korean waters in winter.Zooplankton, samples were collected and temperatures and salinities were recorded at 130 stations around Korean peninsula in the Yellow Sea and the northern East China Sea (ECS), using a Bongo net and CTD in winter, 2016. Research areas using K-mean clustering based on temperatures and salinities were divided into six water bodies:the North Korea Cold Current (NKCC), the East Korea Warm Current (EKWC), the Jeju Warm Current (JWC), the Yellow Sea Warm Current (YSWC), the Yellow Sea (Y1), and mixed water. The indicator indices for water bodies were calculated using INSPAN (Indicator Species Analysis).NKCC, YSWC and Y1 were represented by high proportions of cold water species of 81, 44 and 41 species, respectively, while EKWC and JWC were relatively dominated by warm water species of 99 and 102 species. The water bodies of Yellow Sea and the northern ECS were greatly similar, but the East/Japan Sea was significantly distinguished. With the Indicator value and distribution, indicator species for water bodies were identified: Scolecithricella minorin the NKCC, Candacia bipinnata, Clausocalanus furcatus, and Pleuromamma gracilisin the EKWC, Scolecithricella longispinosa and Euchaeta plana in the JWC, Centropages abdominalis in the Y1.Distributions of zooplanktons and the similarity of community structures were determined by the interaction of water bodies. Zooplankton species can be used as indicator of water bodies because of their dependence on ocean currents.East Sea, Indicator species analysis, Zooplankton

“…The anchovy mainly feed on zooplankton and phytoplankton (Kim et al, 2013;Kim et al, 2017), but zooplankton was not considered directly in this study since the zooplankton biomass data from the Korea Ocean Data Center have a narrower spatial distribution than the area required for MaxEnt construction. Thus, the CHL, as an indicator of phytoplankton, which is associated with changes in zooplankton biomass (Kang and Kim, 2008;Kim and Kang, 2020), was considered in this study.…”

Anchovy (Engraulis japonicus), a commercially and biologically important fish species in Korean waters, is a small pelagic fish sensitive to environmental change. Future changes in its distribution in Korean waters with significant environmental change remain poorly understood. In this study, we examined the projected changes in the seasonal anchovy habitat in Korean waters in the 2050s under three representative concentration pathways (RCPs; RCP 2.6, RCP 4.5, and RCP 8.5) by using a maximum entropy model (MaxEnt). The MaxEnt was constructed by anchovy presence points and five environmental variables (sea surface temperature, sea surface salinity, sea surface current speed, mixed layer depth, and chlorophyll-a concentration) from 2000–2015. Future changes in the anchovy habitat in Korean waters showed variation with seasonality: in the 2050s, during winter and spring, the anchovy habitat area is projected to increase by 19.4–38.4%, while in summer and fall, the habitat area is projected to decrease by up to 19.4% compared with the historical period (2000–2015) under the three different RCPs. A substantial decline (16.5–60.8%) is expected in summer in the East China Sea and the Yellow Sea—main spawning habitat. This considerable decrease in the spawning habitat may contribute to a decline in the anchovy biomass, relocation of the spawning area, and changes in the reproduction timing in Korean waters. Our findings suggest that seasonal variation of the anchovy habitat should be considered to ensure effective future management strategies for the effect of climate change on fisheries resources, particularly for environmentally sensitive species, such as anchovy.

The heat flow (65 mW/m 2 ) was taken from the presentday heat flow distribution in the Central Subbasin, predicted by the spherical harmonic method (Han and Keehm, 1996).…”
