摘要
Abstract
The status of fishery resources was evaluated by the data collected by the bottom trawls in the southwestern waters of Dalu Island. The results showed that 28 species of nekton were found including 12 species of fish, 5 species shrimp, 8 species crab and 3 species cephalopod. With regard to the index of relative importance ( IRI) , Crangon affinis, Pagurus ochotensis, Pugettia sp. were dominant species in spring, and Palaemon gravieri, Callionymus richardsoni, Liparis tanakae were in autumn. In spring, 15 species of nekton were found including 7 species of fish, 7 crustaceans and 1 cephalopod species. And 23 species of nekton were found in autumn including 8 species of fish, 13 crustaceans and 2 cephalopod species. The average richness index was 0.97 (0.49-1.38), the average of species diversity index was 1.00 (0.41-1.86), and the average evenness index was 0.30 (0.13-0.58).关键词
