| Abstract: | Two adjacent Portunus trituberculatus culture ponds with similar hydrological environment in Sanmen Bay,Ninghai County,Zhejiang Province were selected to compare the effects of "submerged aeration system"(experimental pond) and traditional waterwheel aeration system(control pond) on water quality and phytoplankton community structure of the aquaculture pond from June to September 2009.The results show that(1) the indices of dissolved oxygen and ammonia nitrogen of the experimental pond with "submerged aeration system" are better than those of the control pond;the mass concentration of dissolved oxygen at the bottom of the experimental pond is kept at above 5 mg/L,while that of the control pond at(4.28~6.45) mg/ L;and at the later period of cultivation,the mass concentration of ammonia nitrogen of the experimental pond was 0.140 mg/L,much lower than that of the control pond(1.360 mg/L).(2) the cell abundance of the algae in the experimental pond is much higher than that of the control pond,and that of green algae is 8.79×108 ind/L;MDS sequencing,ANOSIM test and SIMPER analysis show significant differences of phytoplankton community structure between the two ponds;at the mid and later period of cultivation,the phytoplankton community structure is stable in the experimental pond and unstable in the control ponds;the dissimilarity of the two ponds is as high as 84.44%,and the dominant species of the former are Oocystis sp.and Phormidium sp.,while that of the latter are diatom and cyanobacteria;Bio-Env analysis show that the correlation between the zooplankton abundance and environmental viable combination with dissolved oxygen is the strongest.(3) Compared to the traditional waterwheel aeration system,the effects of "submerged aeration system" to improve the DO mass concentration of the aquaculture pond are obvious,and it can also improve the water quality and stabilize the community structure of the algae in the farming pond during the cultivation. |
