大连市沿海污损生物种类及分布的研究

1997 年9 月～1998 年9 月, 选取了大连市区沿海的3 个点进行了3 次污损生物调查。共获大型污损生物102 种, 其中优势种类有: 石莼、水螅类、紫贻贝、端足类、纹藤壶和海鞘类。最大双月湿重为2974 g/m2 , 最大覆盖面积为100 % 。3 个点的种类组成差异不大, 但湿重差别较大。

Study on species composition and distribution of fouling organisms in the waters of Dalian coast

Species composition and distribution of fouling organisms in the waters of Dalian coast were studied by suspanding plans in three sample sites from Doctor,1997 to July, 1998 102 speies of fouling organisms were recorded The dominant species were Ulva lactuca, Clytia sp , Mytilus galloprovincialis, Jassa falcata, Caprella scaura, Caprella acanthogaster, Balanus amphitrite amphitrite, Styela clava, Ciona intestinalis, Botrylloides violaceus, etc The bimonth maximum biomass of these fouling organisms were 2974 g/m 2(wet weight) and maximum surface covered by these fouling organisms was 100%. There was no significant difference between two stations in species composition, but, significant diffrence in biomass (wet weight)
