Abstract

Chronic action of adverse factors on the body leads to
violations of cytogenetic stability and accumulation of chromosomal anomalies
in cells of the body. Therefore, it is expedient to use the micronuclear test,
which belongs to one of the most effective methods, and allows to determine
the action of substances, which occur during the start of biofilter, on the
structure of chromosomes and to detect genetic changes in cells of the fish.
The purpose of work was to investigate the formation of micronuclei in cells
of gills of hatchling of rainbow trout during the launch of biofilter RAS for the use of
polypropylene filler RK PLAST in it. As a result of histological evaluation of cells of
gills of rainbow trout, three types of micronuclei were identified. The 1 st type
included cells of gills of hatchling of rainbow trout that contained 1 micronucleus,
which was located at a great distance from the main nucleus, the 2 nd type included
cells of gills that contained 2 micronuclei, which were closer to the periphery of
cells, and the 3 rd type - cells of gills that contained 3 or more micronuclei.
The vast majority of cells of gills of rainbow trout contained 1-2 (80 %),
and also cells with 3 micronuclei were encountered.
Keywords: nitrite, rainbow trout, biofilter, micronuclei
