春、秋季东海大桥海上风电场水域鱼类群落结构
Fish community structure in the offshore wind farm of the East China Sea Bridge in spring and autumn
摘要
Abstract
To determine the composition of the fish community at the offshore wind farm located at the East China Sea Bridge, a cluster analysis and multivariate statistics are applied to analyze species composition, dominant spe-cies, and fish communities. Results identify 18 species belonging to 6 orders, 9 families, and 15 genera. Peciformes are the largest percentage order (50%) and Gobiidae the largest percentage family (44.4%) within this order. Domi-nant species in spring are Cynoglossus joyneri, Collichthys lucidus, Chaeturichthys stigmatias, and Trypauchen vagina, and dominant species in autumn are C. lucidus, Harpadon nehereus, and Coilia mystus; C. lucidus is the dominant species with respect to its representation in both season. Cluster and non-metric multidimensional scaling indicate that the fish community at this offshore wind farm can be clustered into two groups, spring and autumn assemblages, and ANOSIM analysis indicates significant differences in the community structure between these two groups (R = 0.851, P < 0.01). The relationship between fish community pattern and water temperature and salinity is determined as dominant using the BIOENV program, with a correlation coefficient of 0.791. Results show that fish such as C. lucidus, C. mystus, and H. nehereus migrate annually to the wind farm for spawning and feeding. There is an obvious difference in the community structure during different seasons, which is mainly related to the different breeding and feeding grounds of typical assemblage species during spring and autumn.关键词
