鱼类死亡规律的研究是计算捕捞种群资源量和可能渔获量的基础,同时也是判断渔业资源利用的程度和状况,以及制订合理利用资源和保护资源措施的理论依据。在鱼类死亡规律的研究中,首先应指出德国有名的鱼类学家Heincke和俄国学者的贡献。本世纪初Heincke为了研究北海比目鱼数量变动的规律,对比目鱼渔获物进行了大量的取样测定(每年25万尾)。Heincke想把测量的结果制成图表,于是产生了这样的困 The study on the law of fish mortality is the basis for calculating the amount of catches and possible catches, as well as the degree and the status of the utilization of fishery resources and the theoretical basis for formulating the measures for the rational utilization of resources and the protection of resources. In the study of the law of fish death, we should first point out the contributions made by the well-known German fish experts Heincke and Russian scholars. Early this century Heincke in order to study the North Sea flounder volume changes in the law, the catch of fish catch a large number of samples were determined (250,000 per year). Heincke wanted to chart the results of the measurements, and that led to such difficulties
