摘要
2001年6月～2002年6月,对大亚湾大鹏澳海水鱼类网箱养殖区及其邻近海域(对照区)大型底栖动物和沉积环境按季节进行了周年5个航次的调查.结果表明,网箱养殖严重污染了养殖区沉积环境,沉积物有机碳和硫化物含量(超一类海洋沉积物质量标准)的超标率分别为88%和100%,硫化物含量约是对照区的3倍.大型底栖动物经鉴定有64种,其中优势种(优势度Y≥0.01)有21种,主要是多毛类的梳鳃虫(Terebellides stroemii)、贝氏岩虫(Marphysa belli)和白色吻沙蚕(Glycera alba)等,季节更替明显.底栖动物出现种数、生物量和个体数量秋、冬季高于春、夏季;空间分布养殖区明显低于对照区,且养殖区多毛类的生物量组成较对照区占优势.
Large macrobenthic animals and sediment environment were investigated for 5 voyage numbers annually from June 2001 to June 2002 on a seasonal basis in the cage fish culture and its vicinity sea area （as control area） in Dapeng Cove Daya Bay. The sediment environment in culture area was polluted seriously by cage culture. The organic carbon and sulfide contents of the sediment exceeded the standards （the standards of first class of Marine sediment quality） with exceeding rate of 88% and 100%, respectively, and sulfide content was about 3 times higher than that in control area. 64 species of large macrobenthic animals were identified of which 21 species were dominant （dominance Y≥0.01）, These species were mainly Terebellides stroemii, Marphysa belli and Glycera alba of Polychaeta, which replaced with season obviously. The species appeared, biomass and individual amount of macrobenthic animals appeared higher in autumn and winter than in spring and summer; the special distribution in culture area was lower obviously than that in control area; and the biomass composition of Polychaeta in culture area was more prior than in control area.
