摘要:

为了掌握多营养层次养殖的海水池塘浮游植物群落变动情况,并为优化池塘养殖模式和生态调控提供科学依据,在海水池塘“鱼-虾-贝”多营养层次养殖期间,定期进行采样检测,分析水体浮游植物群落及其与营养盐含量的相关性。结果显示,养殖池塘浮游植物种类数高于自然海域,池塘浮游植物细胞密度除养殖初期部分稍低外,养殖中后期均高于自然海域。养殖初期池塘水体浮游植物以中肋骨条藻(Skeletonema costatum)为优势种,中期以锥状斯克里普藻(Scippsiella trochoidea)为绝对优势种,后期以中肋骨条藻、米氏凯伦藻(Karenia mikimotoi)、锥状斯克里普藻为主要种。池塘浮游植物种类多样性指数(H')、均匀度指数(J)波动明显大于自然海域。池塘浮游植物群落呈现由硅藻占优势向甲藻占优势演替的趋势,而自然海域均以硅藻占绝对优势。米氏凯伦藻细胞密度与活性磷酸盐含量极显著相关。

Abstract:

In order to study the changes of phytoplankton community in fish-shrimp-shellfish integrated multi-trophic aquaculture seawater ponds and provide a scientific basis for the optimization of culture model and the ecological regulation of aquaculture ponds, sampling and detection were carried out regularly to analyze the phytoplankton community in water and its correlation with nutrient content during the culture period. The results showed that the species number of phytoplankton in the ponds was higher than that in the natural sea areas. The cell density of phytoplankton in the ponds was higher than that in the natural sea areas in the middle and late stage of culture, except that it was slightly lower in the early stage of culture. Skeletonema costatum was the dominant species in the early stage of culture, Scippsiella trochoidea was the absolute dominant species in the middle stage, and Skeletonema costatum, Karenia mikimotoi and Scippsiella trochoidea were the main species in the later stage. The fluctuations of phytoplankton diversity index (H') and evenness index (J) in the ponds were significantly greater than those in the natural sea areas. It showed a trend of succession of phytoplankton community in the ponds from diatoms to dinoflagellates, while diatoms were absolutely dominant in the natural sea areas. There was a significant correlation between the cell density of Karenia mikimotoi and the content of active phosphate.
