Abstract

The accuracy of estimating the relative abundance of generations of fish species under conditions of incomplete initial information is analyzed. Using the example of bream from the Kuibyshev Reservoir, it is shown that, if the information on the age structure is lost for 1 to 8 years, the error in estimating the abundance of generations averages from 5 to 15%. This makes it possible to apply this modification of the method of loss from fishing to estimate the abundance of fish generations in the current conditions. This method of estimating the number of generations may be useful in the analysis not only of fish, but also of other aquatic organisms.

在初始信息不完整的情况下评估鱼类种群数量的准确性

摘要

分析了在初始信息不完整的情况下估计鱼类世代相对丰度的准确性。以居比雪夫水库的为例，表明如果年龄结构信息丢失1至8年，则估计世代数量的误差平均为5％至15％。这使得有可能将对捕鱼损失方法的这种修改应用于在当前条件下估计鱼类种群的丰度。这种估算世代数的方法不仅可用于鱼类，而且还可用于其他水生生物的分析。
