On the biological characteristics and resource status of Acetes chinensis population in Cangnan sea area
摘要
Abstract
To understand and master the population biological characteristics and resource development status of Acetes chinensis in Cangnan sea area,a total of 2 286 samples of A.chinensis were collected on board the Cangnan A.chinensis production fishing vessels in May and August 2022,November 2022,and February 2023.Biological characteristics such as body length,body weight,and sex were measured,and the FiSAT II software was used to evaluate the growth,mortality parameters and resource utilization.The results showed that during the survey period,the average female-male sex ratio of A.chinensis was 1.66:1.The body length range was 11.2-50.1 mm,with an average of(35.1±6.40)mm,and there was a significant difference in body length distribution between males and females(P<0.05).The optimal fitting obtained the relationship between body weight and body length as W=2.264 8×10-5L2.569 9,and the growth equations for body length and body weight were Lt=49.88[1-e-1.5(t+0.15)]and Wt=0.523[1-e-1.5(t+0.15)]2.569 9,respectively.The natural mortality coefficient(M)was 3.24 a-1,and the fishing mortality coefficient(F)was 1.13 a-1.The minimum legal fishing length(Lc)was 29.0 mm,which was equal to the optimal fishing length(Lopt)of 29.0 mm.The annual resource exploitation rate(E)was 0.259 which was less than E0.5(0.392).The results indicated that the resources of A.chinensis in Cangnan sea area were in a state of mild development,an under-developed state.Given that the A.chinensis fishing industry in Cangnan sea area is a pillar industry for local fishermen to increase their incomes,and there are already mature precedents for implementing quota fishing of A.chinensis during the summer fishing moratorium in China,it is recommended to appropriately explore the implementation of quota fishing of A.chinensis during the summer fishing moratorium in Cangnan sea area.关键词
