Purpose. Characterization of bacteria and zooplankton in rearing ponds using traditional fertilizers: cattle manure and bird droppings in modern conditions for fish farming.

Methodology. Material collection and processing were carried out according to conventional hydrochemical and hydrobiological methods.

Findings. We consider forming of bacteria and zooplankton component of natural food base of Irkliiv herbivorous fish nursery rearing ponds under the influenced of traditional organic fertilizers such as bird droppings (0,12 t/ha) and cattle manure (2,0 t/ha). Each pond was planted by ongrowing Nyvka carp larvae (40,0 thousand ind./ha) with silver carp (1,0 thousand ind./ha) and grass carp larvae (1,0 thousand ind./ha). Qualitative and quantitative development of bacteria and zooplankton in fish-breeding ponds was investigated. The results show that in the development of the studied invertebrate groups of zooplankton in production ponds had no significant differences, except for rotifers, which group prevailed by the biomass to 3,6 times in the pond with the introduction of humus.

Originality. The parameters of bacteria and zooplankton by the application of traditional organic fertilizers at present fish farming are studied.

Practical value. These quantitative indicators of bacteria and zooplankton of fish-rearing ponds with water supply from Kremenchug reservoir, the application of cattle manure and bird droppings could be offered as an optimum data at present fish production stage.

Keywords: bacterioplankton, zooplankton, bird droppings, cattle manure.
