中文摘要:
      为研究凡纳滨对虾养殖过程中水质变化特征及其与浮游植物群落结构之间的相关性,本实验于2016年4月至9月在上海市奉贤区某养殖场开展凡纳滨对虾养殖池塘中水质及浮游植物的监测,分析浮游植物群落结构变化与水质因子的相关性。结果显示,凡纳滨对虾养殖池塘中共鉴定出113种浮游植物(包含20个未定种),分别属于7个门、59个属别,从种的数量上来看,绿藻门 > 硅藻门 > 蓝藻门 > 裸藻门 > 黄藻门 > 金藻门 > 甲藻门,18种(含3个未定种)优势种,第一批次共鉴定出10种(含1个未定种)优势种,第二批次共鉴定出14种(含2未定种)优势种,养殖初期优势种为硅藻门,之后是绿藻门,最终以蓝藻门为优势种。对浮游植物群落结构与水质因子进行典范对应分析可知,绿藻门主要受pH、无机氮的影响(包括总氨氮、亚硝酸盐氮、硝酸盐氮),蓝藻门主要受磷含量的影响(总磷和活性磷),硅藻门主要受温度的影响,因此在养殖过程中要格外关注温度、pH以及氮磷含量的变化。
英文摘要:
      In order to study the correlations between the change of water quality and phytoplankton community structure during the process of Litopenaeus vannamei aquaculture, the water quality was tested and the changes of phytoplankton community structure were analyzed from April 2016 to September 2016 in an aquaculture farm in Fengxian District, Shanghai, and then the correlations between phytoplankton community structure and water quality factors were analyzed. The results showed that there were 7 phyla, 59 genera, 113 species (including 20 unnamed species), Chlorophyta > Bacillariophyta > Cyanophyta > Euglenophyta > Xanthophyta > Chrysophyta > Pyrrophyta, and 18 dominant species (including 3 unnamed species)——there were 10 dominant species (including 1 unnamed species) in the first season and 14 dominant species (including 2 unnamed species) in the second season. Dominant species were Bacillariophyta at beginning, then Chlorophyta and finally Cyanophyta. According to CCA analyzing, Chlorophyta is mainly affected by pH and nitrogen (including ammonia nitrogen, nitrate nitrogen, nitrite nitrogen), Cyanophyta by phosphorus (including total phosphorus and active phosphorus), and Bacillariophyta by temperature, so we should pay more attention to temperature, pH, nitrogen and phosphorus.
