摘要: |
研究了杂色鲍(Haliotis diversicolor) 越冬期养殖环境中的浮游动物种类组成和密度变化。共检测到浮游动物33种,其中纤毛虫(Ciliata)23种,鞭毛虫(Mastigophora)5 种,轮虫(Rotatoria)4种,桡足类(Copepoda)1种。优势种是奇异猛水蚤(Miracia efferata)和海洋尾丝虫 (Uromena marinam);钩状狭甲轮虫(Colurella uncinata)和偏体虫(Dysteria lancolata)为常见种。砂井 水养殖可以减少养殖环境中原生动物以外的各种浮游动物种类。 |

The density and species number changes of zooplanktons in abalone cultured ponds during the winter |

Abstract: |
The zooplankton species composition and density change in abalone culture ponds during the winter were studied in this paper. Totally 33 species of zooplanktons,including 23 ciliates, 5 flagellates, 5 rotifer and 1 copepod were found during the investigation. The dominant species were Miracia efferata and Uromena marinam, and both Colurella uncinata and Dysteria lancolata were familiar species. The water from the sand beach well could reduce the zooplankton species except protozoan. |
