Abstract:
The biomass of phytoplankton in intensive cultivated carp ponds in Tongliao was between 23.6-53.8mg/ L.Scenedesmus,Chlorococcum,Chlorella,Coelastrum etc,which were contained in Chlorococcales were more in there ponds,and the amount of these species in Chlorococcales was 43% in that of the total biomass of phytoplankton.Cryptomonas,Euglena etc,which had flagellum also had certain amount,and was 37% in that of the total phytoplankton biomass.The primary productivity was 402.6kg(wet weight)/ h•m2•day,and it could provide 1553.4kg/h•m2•day output of the silver and bighead carp.
Key words:
Intensive cultivated catp pond,
