Response of Japanese anchovy (Engraulis japonicus) to the Pa-cific Decadal Oscillation in the Yellow Sea over the past 400 a
文献摘要：
Quantitative identification of long-term changes in the abundance of Japanese anchovy (Engraulis japonicus) in the Yellow Sea is particularly important for understanding evolutionary processes of the Yellow Sea ecosystem.Unfortunately, the driving mechanisms of climate variability on the anchovy are still unclear due to the lack oflong-term observational data. In this study, we used the fish scale deposition rate in the central Yellow Sea toreconstruct the time series of the anchovy stock over the past 400 a. On this basis, we further explored the impactsof the Pacific Decadal Oscillation (PDO) on the anchovy. Our results show that the anchovy stock is positivelycorrelated with the PDO on a decadal time scale. In addition, anchovy abundance was relatively high during1620–1860 AD (the Little Ice Age, LIA), though in a state of constant fluctuation; anchovy abundance maintainedat a relatively low level after ～1860 AD. In particular, followed by overfishing since the 1980s, the anchovy stockhas declined sharply. Based on these findings, we infer that fluctuations of the anchovy stock may be regulated bybasin-scale "atmosphere–ocean" interactions. Nevertheless, the role of overfishing should not be ignored.
