天津海域春夏季节游泳动物的组成特征
Nekton composition in the coastal waters off Tianjin in spring and summer
摘要
Abstract
The characteristics of nekton composition were preliminarily analyzed based on the bottom trawl surveys in the southern coastal waters off Tianjin in May and August 2014. Results indicated that 36 species were collected from the bottom trawl surveys. The mean densities were 126297.13 ind/km2 and 1494.40 kg/km2. The species richness d, the Shannon diversity index H, and the evenness index J were 1.083, 0.592, and 0.537 for the nekton community, respectively. The dominant species were Oratosquilla oratoria, and the important species wereLoligo beka,Charybdis japonica,Clupanodon punctatus. and Chaeturichthys hexanema. The fishery resources were char-acterized by fishes of low values.关键词
