Community Structure Characteristics of Fishes in the Coastal Area of South Zhejiang during Autumn and Winter
摘要
Abstract
According to the investigation results of fishery resources in the coastal areas of south Zhejiang during November of 2015 (Autumn)and February of 2016 (Winter),the composition,quantity,and variation of fish species were analyzed and reported by using standardized catch rate as the quantity index of fish resources distribution.The results showed that a total of 115 species of fish were identified in this area,which belonged to 91 genera,51 families,13 orders and 2 clas-ses.Among these species,most quantity belonged to Perciformes,followed by Pleuronectiformes, third Clupeiformes.In the aspect of thermal adaptation,fishes in this area can be divided into warm-water species and warm-temperate species,between which the warm-water species were dominant with 78 species,accounting for 62.9% of total catch.In autumn,the average biomass of each station was 411.65kg/km2 and the abundance was 1.26×105 ind/km2.And there were 97 species of fish identified in this season,among which the dominant species were Harpodon ne-hereus,Trichiurus japonicus and Collichthys lucidus etc that composed 64.82% of total catch. Compared with autumn,the average biomass of each station in winter was lower (27.89 kg/km2),while the abundance was higher (3.07×105ind/km2).In addition,a total of 68 species of fish were caught in winter,when Harpodon nehereus and Collichthys lucidus were still dominant species,the dominance of Lophius litulon increased obviously.The result of abundance biomass curve showed thatW of curve was negative in both two seasons.TheW value was -0.066 in au-tumn,implied that the fish community suffered from moderate interference.Whereas,the W value is -0.13 in winter,and the biomass dominance curve was almost totally beyond the quantitative dominance curve,which suggested that the fish community may have a serious disturbance.关键词
