Phytoplankton community and abiotic environmental factors in commercial Hyriopsis cumingii ponds at Zhuji
摘要
Abstract
In this study, we investigated the species composition and biomass of phytoplankton and abiotic environmental factors in ten commercial Hyriopsis cumingii ponds located in Zhuji City, Zhejiang Province, from August 29 to September 1, 2011. A total of 51 genus of phytoplankton were observed, and Merismopedia sp. , Microcystis sp. , Coelosphaerium sp. and Scenedesmus sp. were the dominant species during the investigation. The biomass of phytoplankton was 0. 71~8. 01 × 108 cell/L, and blue-green algae account for 71~97% of the phytoplankton biomass. Dissolved oxygen (4~12 mg/L) was relatively high, while Secchi depth (33 cm), total nitrogen (TN, 1. 933~4. 062 mg/L), total phosphorus (TP, 0. 154~1. 010 mg/L), chemical oxygen demand (6. 49~10. 06 mg/L) and TN/TP were low in the ponds. According to results of this investigation, it is recommended that the stocking density of omnivorous fishes and input of formulated fish feed should be increased, while the amount of duck manure input should be reduced, in these commercial ponds.关键词
