Assessment of the Impact of Integrated Pollution on the Monitoring of Biodiversity in Fisheries

Abstract

Results are presented of the comparative analysis of frequency of erythroid cells with micronuclei and “tailed” nuclei and of the interphase nuclei indices of red blood cells in the peripheral blood of bester, a sturgeon hybrid. The differences are found in the frequency of occurrence of abnormal red blood cells between the two groups of fish kept in cages in natural water (river) and in ponds with water supplied through a sedimentation basin. Despite these differences, the number of erythrocytes with chromosomal abnormalities in the bester of both groups is close to normal. However, the number of erythroid cells with micronuclei and “tailed nuclei” prevailed in the fish held in river cages. It was suggested that comparative cytogenetic monitoring of fish can be used not only to characterize the environment of water bodies, but also promote the rational organization of artificial reproduction of aquatic organisms that would contribute to the conservation of biodiversity of aquatic biological resources.
