山东近岸3处人工鱼礁区VPUE的分析研究
Analysis of Value Per Unit Effort of Three Artificial Reefs of Shandong Coast
摘要
Abstract
The fixed gill net survey was carried out in three artificial reefs and correspondedcontrol areas respectively off Shandong Coast from Sept.,2012 to Aug.,2013.Based on the survey,the value per unit effort (VPUE) was used as an indicator for an economic analysis of the catch from the artificial reefs to test the potential to increase fishing incomes and provide relevant suggestions to develop and manage three artificial reefs.The study identified the commercial species by the VPUE of each species from catches,and analyzed the different species abundance and richness between sites.Nonmetric multi-dimensional scaling (MDS) was used to analyze the difference of composition of VPUE from variety of sites.Difference was shown in commercial species abundance and richnessbetween reefs andcontrol area.Differences were shown in commercial species abundance and richness between locations.Locationwas the significant factor that influencedthe composition of VPUE(R=0.414,P=0.003),insteadof season (R=-0.052,P=0.637＞0.05).The results demonstrated the potential (regionally different)ofincreasing fishing income at all sites.In the three artificial reefs,compared with the control,the average VPUE of artificial reefs increased by 160.8％,among them,the average VPUE of the artificial reefs in Lidao (ARL) increased the most (by 312.7％).The Artificial reefs in Qiansandao (ARQ)and the artificial reefs in the Xiaoshidao (ARX) increased by 98.3％ and 71.3％,respectively.关键词
