Nursing ponds for fish farming and ecology: whether the effective compromise proposal is possible?
Article is follows the results of study of effective nursing ponds in warm waters of hybrid sterlet-beluga in polyculture with phytophagous fishes, using the space sectioning of the basic and additional entities. Results of the research show augmentation in fish capacity and survival rate in the grown fishes, decrease in expenses and raise in feedstuff conversion. The system of calculation of the parameters is presented, allowing to estimate resource-saving and ecological effect of the new type of cultivation.
