罗非鱼养殖池塘水和表层沉积物中蓝藻的群落结构及影响因素研究
Community structure of cyanobacteria in water and surface sediment of tilapia ponds and the influencing factors
摘要
Abstract
In order to investigate the community structure and diversity of cyanobacteria in water and sediment of tilapia ponds,the Illumina high-throughput sequencing and the bioinformatics analysis were performed.The results showed that there were significant differences of cyanobacteria community structure between water and surface sediment samples.Nonetheless,the dominant groups in these two habitats were the same,which were Synechococcales,Cyanobacteria_norank and Chroococcales.Further researches indicated that the cyanobacteria community in water was affected by the monthly variations,and was closely related to the net input of nitrogen to the ponds systems.However,the cyanobacteria community in surface sediment was more affected by the ponds variations and was related to the net input of phosphorus to the ponds systems.To sum up,the tilapia cultivations in the ponds systems affected the cyanobacteria communities in water and surface sediment more by the way of nutrients input than by direct feeding.关键词
