摘要: 以往的鱼类种群动态研究和管理措施,多数采用了被研究鱼类捕捞产量取代资源量的方法,两者之间不仅存在着巨大差异,而且时间尺度较短,种群自然波动、人为干预和全球气候变化引起的鱼类资源变化相互交织,难以理清引起鱼类种群变化的主导因素.已有研究表明,沉积物中完好保存的鱼鳞能够作为鱼类种群信息指标,更客观地追溯百年甚至千年尺度上的鱼类种群动态.本研究首次对东、黄海表层沉积物样品的鳀鱼鱼鳞沉积信息进行了调查,发现黄海中部作为鳀鱼的主要越冬场,其越冬群体基本能够反映东、黄海鳀鱼种群数量,对应的鱼鳞沉积量也最大.因此,采集黄海中部2个站位的柱状沉积样品进行分析,结果显示黄海中部的厌氧沉积环境有利于鱼鳞完整保存,2个站位之间的鱼鳞沉积率呈现显著的相关性.通过比较近代鱼鳞沉积率和鳀鱼资源量,进一步证实黄海中部厌氧沉积环境下的鳀鱼鱼鳞沉积信息可作为种群信息指标反演鳀鱼种群长期变化的潜力.本研究拟通过这种方法重建东、黄海陆架鳀鱼种群长期变化,并通过鳀鱼、栖息生态环境和全球气候变化之间的关联性分析,为将来探索鱼类种群变化的驱动机制提供一种更加有效的科学手段.Abstract: Many studies have revealed that anchovy has exhibited large variability in population size on decadal timescales. 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. The calibration of downcore SDRs to the standing stocks of anchovy further validated that SDR is a reliable proxy to reconstruct 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.
