许多研究表明了鱼类在十的 timescales 上在人口尺寸展出了大可变性。然而，有关鱼类人口的如此的工作主要基于短历史的钩子记录。为了在鱼理解可变性的原因，储备(自然或人为) 并且校准在钩子和站的股票之间的错误，从人的影响最小或可以忽略的时间开发鱼股票的长期的时间系列是必要的。从沉积记录的很好保存的鱼规模被认为是在最后世纪揭示鱼人口动力学的历史的有用指示物。鱼类规模首先在黄海和华东海上被分析，当最大的 overwintering 为日本鱼类(Engraulis 装饰用的梨树) 磨擦了，最大的丰富在被考虑的中央南方黄海被发现。因此在中央南方黄海，最后 150 年盖住的二个核心为估计鱼可伸缩被收集流动。规模免职率(SDR ) 记录证明十的规模 SDR 在有独立年表的核心之间显然是协调的。到鱼类的站的股票的 downcore SDR 的刻度进一步验证了那 SDR 是一个可靠代理重建在缺氧的条件在沉积占优势的中央南方黄海动态的长期的鱼类人口。当与另外的生产率代理集合了时， SDR 能在海洋的生产率与变化被联系并且可以做贡献决定强迫的因素并且阐明，这将被期望在未来的过程的机制。

英文摘要：

Many studies have revealed that anchovy has exhibited large variability in population size on decadal tim-escales. However, such works concerning anchovy population are mainly based on short historical catch records. In order to understand the causes of variability in fish stocks （natural and/or anthropogenic） and calibrate the error between catches and standing stocks, it is essential to develop long-term time series of fish stocks from the time when human impacts are minimal or negligible. Well preserved fish scales from sediment record are regarded as useful indicators revealing the history of fish population dynamics over the last centuries. Anchovy scales was first analyzed over the Yellow Sea and East China Sea and the largest abundance was found in the central South Yellow Sea where is regarded as the largest overwintering ground for Japanese anchovy （Engraulis japonicas）. Thus in the central South Yellow Sea, two cores covering the last 150 years were collected for estimating fish scale flux. The scale deposition rate （SDR） records show that the decadal scale SDRs were obviously coherent between cores with independent chronologies. Thecalibration of downcore SDRs to the standing stocks of anchovy further validated that SDR is a reliable proxy to recon-struct the long-term anchovy population dynamic in the central South Yellow Sea where anoxic conditions prevail in the sediment. When assembled with other productivity proxies, it would be expected that SDR could be associated with changes in oceanic productivity and may make a contribution to determine the forcing factors and elucidate the mechanism of the process in future.
