泉州湾红树林区鱼类物种多样性及其对鱼类生态的支撑作用
Fish Biodiversity and Ecological Support for Fishes in Quanzhou Bay Mangrove Zone
摘要
Abstract
Seasonal changes in species composition,ecotype,dominant species and biodiversity of fishes were analyzed in this study. Sampling was conducted in Quanzhou Bay mangrove zone in 4 seasons year-round from 2013 to 2014.A total of 72 fish species were recorded,belonging to 34 families,9 orders and 1 class,with 8.7% warm-temperate species and 91.3% warm-water species.Investi-gation showed that the dominant species varied with season.Dominant species in spring and summer mainly consisted of resident spe-cies,such as Bostrychus sinensis,Gobiidae spp.,etc.;while dominant species in autumn and winter mainly consisted of non-resident and pelagic species,such as Mugilidae spp.,Clupanodon thrissa,Coilia grayii,etc..Number of species,the species richness index (D),Shannon-Wiener index (H')and Pielou evenness index (J )showed a tendency of summer > autumn > winter >spring.The species richness index (D)and Shannon-Wiener index (H')in Quanzhou bay mangrove zone were relatively high,compared with other similar mangrove areas.In addition,the ecological function of Quanzhou bay mangrove zone for fishes was discussed based on nursery,feeding and shelter.Our study suggests that the ecological support of Quanzhou bay mangrove zone for fishes is important and there is a complete oceanic food web in Quanzhou bay mangrove zone,which emphasizes the importance of the protection of man-grove.关键词
