河蟹生态养殖池浮游植物功能类群的结构特征
Structure of phytoplankton functional groups in the ecological farming crab ponds
摘要
Abstract
In order to explore the influence of phytoplankton community structure in the ecological farming crab pond, we collected phytoplankton from the crab ponds and the source of water from April to October 2013 in Maogang Town, Songjiang District, Shanghai. The phytoplankton species composition, density, biomass and biodiversity were analyzed. 11 dominant species of all 105 phytoplankton species were detected, finding that the B, D, J, LO , X1, WO , X2, S1, MP were the common species in the eco-logical farming crab ponds. Average density of the biological pond phytoplankton was 282.58×104 cells/L, the average biomass was 1.59 mg/L, and the range of Shannon-Wiener diversity index was 2.11 to 3.09. Average density of the phytoplankton biomass from the water source samples was 175.13×104 cells/L, the average biomass was 0.99 mg/L, and the range of Shannon-Wiener diversity index changed from 1.70 to 2.79. Average density of phytoplankton in crab pool was significantly higher than that in the river water during two periods from May 14 to June 14 and from July 29 to Aug. 29. The average crab pool phytoplankton biomass was signifi-cantly higher than that in the source of water at days of May 30, June 14, and from July 29 to Aug. 29. Phytoplankton Shannon-Wiener diversity was significantly higher than that in the source of water in periods from May 14 to June 14 and from Aug. 14 to Sept.15. In summary, the crab pond phytoplankton species, density, biomass and biodiversity with much stable community were higher than those in the source of water.关键词
