Abstract
Based on the information of fish catches in Harbin section of Songhua River from summer 2023 to Spring 2024,FISAT II software was used to evaluate the growth and population status of Carassius auratus samples in order to understand the variation trend and growth of Carassius auratus population resources.It provides a scientific basis for the protection of fishery management resources and the health integrity of the ecosystem in this region.The re-sults showed that the progressive body length(L∞)of Carassius auratus in this area was 183.75 mm.The growth coefficient(K)was 0.66;The turning point age and critical age were 1.51a and 1.32a,respectively.The exploi-tation rate of Carassius auratus population was 0.52.The results show that the Carassius auratus population re-sources in Harbin section of Songhua River have been over-exploited,and the phenomenon of low age and minia-turization of fish is obvious.Therefore,in order to ensure the population size of Carassius auratus in Harbin section of Songhua River,all related nets should be controlled above 126.15 mm.关键词
