Environmental assessment of fry fish in the Zaporozhian reservoir
We have performed comprehensive studies of the fish community of the coastal sites in the Zaporozhian reservoir with different degree of anthropogenic load. It was found that the impact in the areas of technological and household wastewater being degraded degradation of structure of coastal fish community with substantial dominance of low-value species, as evidenced by a high index of cenotic significance, as well as reduce the morphological characteristics of fry fish compared to ecologically favorable areas. In areas with high anthropogenic load have been revealed to various adaptation mechanisms of erythropoiesis in fry fish of different ecological groups to the hypoxia.
