摘 要：
为了评价大长山人工鱼礁区许氏平鮋(Sebastes schlegelii)资源利用状态,为当地许氏平鮋资源的合理开发与管理提供科学依据,采用基于体长的贝叶斯评估方法(LBB)对2011-2015年大长山人工鱼礁区许氏平鮋资源进行了评估。研究结果表明大长山人工鱼礁区许氏平鮋最优体长L_(opt)为31cm,最佳开捕体长L_(c-opt)为28cm,平均M/K=1.5、F/K=4.82、Z/K=6.34、F/M=3.24,许氏平鮋最优现存资源量与原始资源量之比B/B_0(F=M,L_c=L_(c-opt))=0.366、实际年平均B/B_0=0.038 6,许氏平鮋最优的单位补充量渔获量Y/R'(F=M,L_c=L_(c-opt))=0.045 9kg,实际年平均Y/R'=0.003 44kg。

摘 要：
In order to evaluate the utilization state of Sebastes schlegelii resources in the artificial reef area of Dachangshan and provide scientific basis for the reasonable development and management of Sebastes schlegelii resources,this paper adopts the bayesian evaluation method(LBB)based on body length to evaluate Sebastes schlegelii resources in the artificial reef area of Dachangshan from 2011 to 2015.Research results show that the Dachangshan artificial reef area for the Sebastes schlegelii optimal length L_(opt)to 31 cm,the best length L_(c-opt) for 28 cm,an average of M/K=1.5,F/K=4.82,Z/K=6.34,F/M=3.24,the Sebastes schlegelii optimal existing resources and the ratio of the amount of original B/B_0(F=M,L_c=L_(c-opt))=0.366,the actual average annual B/B_0= 0.038 6,the optimal unit for the Sebastes schlegelii transshipment catches Y/R'(F=M,L_c=L_(c-opt))=0.045 9 kg.Actual annual average Y/R'=0.003 44 kg.
