The research results determined that the abiotic and biotic factors in fish ponds of the Republic of Belarus are favorable for growing uneven-aged paddle-fish. The average biomass of dominant green algae and zooplankton of 10-40 g/m3 per season provide high weight gain. The greatest increase in body weight (2.0 and 1.61 kg respectively) of six- and eight year paddle-fish specimen was observed at the 2 specimen per hectare stock density. The eight-year average specimen body weight reaches 9.8 kg, the absolute growth reaches 1.2 kg, the relative growth reaches 11.52%; for the six-year species it reaches 5.9 kg, 1.4 kg and 31.11% respectively, at the 10 specimen per hectare stock density under the Belarus pond farm conditions.
