胶州湾中部海域虾类群落结构及其多样性
Community structure and diversity of shrimp assemblages in the cen-tral waters of Jiaozhou Bay, China
摘要
Abstract
Based on monthly bottom trawl surveys in the central waters of Jiaozhou Bay from September 2008 to August 2009, a study on the community structure and diversity of shrimps was carried out using an index of rela-tive importance, ecological diversity indices, multivariate analysis and other methods. Survey results indicated that 17 shrimp species, belonging to 15 families and six genera, were caught. The relative monthly shrimp re-source, which was highest in September, October and June, varied dramatically among months. The average catch weight per haul (h) ranged from 223.9 g/h to 3 422.9 g/h, and the average catch number per haul varied from 41 ind/h to 1 608 ind/h. Monthly changes were observed in the dominant species Trachysalambria curvirostris, Parapenaeopsis tenella and Alpheus japonicus. There were severe changes in the diversity index among months, with the indices in spring and summer being higher than those in autumn and winter. The Margalef’s species rich-ness index (D), Shannon-Wiener diversity index (H') and Pielou’s evenness index (J) of the community structure ranged from 0.77-1.89, 0.90-2.34 and 0.26-0.76, respectively. MDS and CLUSTER analysis identified four month groups, comprising Group I (April and May), Group II (December, January, February and March), Group III (June, September and October) and Group IV (July, August and November), for shrimp communities during the entire year in this area. ANOSIM analysis revealed significant differences in species composition between Group II and Group III or Group II and Group IV, but no significant differences between other groups. Typical species within-group and discriminating species between groups had a significant influence on the community structure. BIOENV analysis showed that bottom water temperature was the most important environmental factor affecting monthly variations in shrimp community structure in the central waters of Jiaozhou Bay.关键词
