摘要: 为了揭示仿刺参养殖池塘生态系统中浮游病毒与环境因子的关系,于2008年3—11月对大连市谢屯地区的仿刺参养殖池塘中的浮游病毒丰度进行了定期检测,同时对水温、pH、溶解氧、盐度、叶绿素a含量、化学需氧量、无机氮、活性磷酸盐、异养细菌等因子进行了监测,对浮游病毒丰度与这些环境因子之间的相关性进行了分析。结果表明:仿刺参养殖池塘中浮游病毒的平均丰度为8.32×1010 VLPs·L-1(最高值为4月的18.2×1010 VLPs·L-1,最低值为11月的1.31×1010 VLPs·L-1),外海水中浮游病毒平均丰度为6.45×1010 VLPs·L-1(最高值为4月的12.6×1010 VLPs·L-1,最低值为6月的2.02×1010 VLPs·L-1),仿刺参养殖池塘中营养盐、水温、pH及盐度对浮游病毒丰度的影响较大,而外海水中叶绿素a和异养细菌对浮游病毒丰度的影响较大。

Abstract: To reveal the relationships between virioplankton abundance and environmental factors in sea cucumber (Apostichopus japonicus) culture pond ecosystem, the virioplankton abundance in an A. japonicusculture pond of Xietun near Dalian City was determined from March to November 2008. In the meantime, the environmental factors such as water temperature, pH, dissolved oxygen, salinity, chlorophyll a, chemical oxygen demand, inorganic nitrogen and phosphorus, and heterotrophic bacterioplankton were monitored, with the relationships between the virioplankton abundance and these environmental factors analyzed. In the A. japonicus culture pond, the virioplankton abundance was the highest (18.2×1010 VLPs·L-1) in April and the lowest (1.31×1010 VLPs·L-1) in November, with an average of 8.32×1010 VLPs·L-1; while in outer sea, the virioplankton abundance was the highest (12.6×1010 VLPs·L-1) in April and the lowest (2.02×1010 VLPs·L-1) in June, with an average of 6.45×1010 VLPs·L-1. The main environmental factors affecting the virioplankton abundance in the A. japonicus culture pond were nutrients, water temperature, pH, and salinity; while those affecting the abundance in outer sea were chlorophyll a and heterotrophic bacterioplankton.
