Abstract

The effect of the microbial preparation «Bioprud» on the formation of the natural fооd base and fish productivity was studied at different terms of introduction on bottom sediments of experimental ponds. The preparation’s positive effect on the outflow of nutrients from bottom sediments as well as indices of natural and total fish productivity of feeding ponds was shown. The greatest increase in marketable fish was noted in the group of ponds, where bottom sediments were treated with the preparation since the autumn of the previous year.
