黄海中南部头足类的群落结构与生物多样性
The community structure and biodiversity of Cephalopoda in central and southern Yellow Sea
摘要
Abstract
In order to understand the community structure and distribution of Cephalopoda in central and southern Yellow Sea, the species composition, biomass distribution and stock of Cephalopoda were analyzed, based on the data collected by bottom trawl surveys in spring, autumn, and winter of 2010-2011. A total of 13 species of Cepha-lopoda, belonging to 3 orders, 6 families, and 6 genus, were harvested. Sepiola birostrata(50.07%) in Spring,Sepia esculenta (40.88%) in autumn, andLoligospp.(68.20%)in winter, were dominant by biomass. The Cephalopoda resource density was the highest in winter (12.72 kg/km2), followed by that in spring (4.85 kg/km2), and was the lowest in autumn (2.52 kg/km2). The difference was not significant( (P>0.05)) between spring and autumn. While the differences between winter and other seasons were significant (P<0.05). The spatial distribution of Cephalopoda biomass was greatly different between 3 seasons. The biomass density was the highest in the northeast and southwest in spring, in the southwest in autumn, and in the center and the northeast in winter. The vertical distri-bution of Cephalopoda biomass changed in different seasons. The biodiversity of Cephalopoda was analyzed, and the results showed that the diversity index including Margalef richness, Pielou evenness and Shannon-Wiener di-versity were the highest in winter, then in spring, and the lowest in autumn. The community similarity was also analyzed and the results showed that the community similarity index was the highest between spring and winter. Comparing 2010-2011 with 1998-2000, the number of Cephalopoda species increased by 5 species, and biomass density increased by 12%.Loligospp. was still the dominant biomass species. The biomass proportion of Sepiolidae spp. increased andTodarodes pacificusdeclined greatly.关键词
