The optimal zoo plankton biomass in fish rearing ponds


Gidrobiologicheskii Zhurnal 12(2): 66-68
The optimal zoo plankton biomass in fish rearing ponds
An increase of the biomass of zooplankton in carp ponds to 40-50 g/m3 (occasionally 100 g/m3) was associated with the accumulation of biogenic elements and organic substances in the water. At a zooplankton concentration of over 50 g/m3, the O2 demand of these organisms attained levels (4-7 mg/m3) corresponding to the normal O2 saturation level of the water. This facilitated the development of toxic and asphyxiating conditions. Zooplankton biomass of 10-20 g/m3 was optimal for the growth of carp at a stocking density of 20 centners/ha, and resulted in a mean daily growth accretion of 4-9 g/individual yearling.
