威海小石岛人工鱼礁海域渔获物群落结构特征及其与环境因子相关性
Catch community structure characteristics and their relation-ships with environmental factors in the Xiao Shidao artificial-reef sea area of Weihai
摘要
Abstract
Fishery resources and environmental elements in the Xiao Shidao artificial reef area and its control area were investigated during 2012–2013 to identify the influence of artificial reefs on species as well as catch commu-nity structure characteristics, which were analyzed using the CLUSTER, one-way ANOSIM, and SIMPER methods. The correlation between the dominant species and environmental factors was analyzed using CCA methods. The cage net survey results showed that the number of species in the southern and northern reef areas was higher than that in the control areas 18, 24, and 31. The dominant fish species throughout the year in the southern and northern reef areas were Charybdis japonica and Hexagrammos otakii. The dominant species in the control area were Glyptocidaris crenularis and Hexagrammos otakii. The size of the fish and crustacean catches in the southern and northern reef areas were higher than that in the control area. CLUSTER and ANOSIM analyses indicated significant differences in catch community structures both among seasons (P<0.05) and between the artificial reef areas and the control area during spring and summer (P<0.05). CCA analysis showed that the major environmental factors af-fecting the distribution of dominant species in reef areas were water temperature, chlorophyll, and dissolved oxygen. In conclusion, construction of artificial reefs ameliorated the catch community structure of the Xiao Shidao artifi-cial reef areas and increased the catch abundance of the dominant economic fish and crustacean species.关键词
