麒麟菜养殖区海域浮游桡足类种类组成与多样性

Species Composition and Diversity of Planktonic Copepods in Culture Zone of Eucheuma

[目的]研究麒麟菜养殖区海域浮游桡足类种类组成与多样性。[方法]于2011年1～12月对麒麟菜养殖区海尾镇海域进行生态环境调查,分析麒麟菜养殖海区浮游桡足类种类组成与多样性,并对其与季节及麒麟菜养殖的关系进行了初步探讨。[结果]此次调查期间共出现了浮游桡足类56种,其中有13种是全年出现的,以夏、秋季较多,春、冬较少;四季共出现优势桡足类9种,出现的生态类型有近岸低盐型、广温广盐型、高温广盐型,其中以近岸低盐类型占主导。麒麟菜丰富区域浮游桡足类种类多样性高于麒麟菜不丰富区域。[结论]麒麟菜养殖和季节变化对浮游桡足类多样性有一定的影响。

[Objective] The research aimed to study the species composition and diversity of planktonic copepods in culture zone of Eucheuma.[Method] The ecological environment of sea area in Haiwei Town of culture zone of Eucheuma was surveyed during 2011.1-2011.The species composition and diversity of planktonic copepod in culture zone of Eucheuma were analyzed and its relationship with the culture of Eucheuma was preliminarily discussed.[Result] 56 species of Copepod were identified in this survey.Among them,13 species occurred yearly.More species of Copepod were found in summer and autumn,while less species were found in spring and winter.9 dominant species found in 4 seasons were neritic and hypohaline type,eurythermal and euryhaline type,hyperthermal and euryhaline type.The dominant ecological type was neritic and hypohaline type.The diversity of the planktonic copepods in richer region in the culture zone of Eucheuma was higher.[Conclusion] The diversity of Copepods were affected by Eucheuma culture and seasonal variation.
