Zhydenko A. Morpho-physiological adaptations of uneven-aged Сyprinus carpio L. groups under adverse influence of ecological factors

The dissertation features peculiarities of forming Cyprinus carpio L.'s adaptation to adverse ecological factors of different nature (herbicides, phenol, ions of lead, low temperatures and winter starvation). The paper defines patterns of functional, morphological, tissue and biochemical transformations occuring in its organism. Morphological and tissue changes in the organism of carps under influence of herbicides (zenkor, derivatives 2,4-dichlorphenoxiacetic acid's derivatives, roundup) are registered within certain periods. Age-referred peculiarities of metabolism in the organism of carp under the influence of organic toxiccants are studied. Correlation of herbicide's chemical component and metabolism of carbohydrates, fibers, lipids, power exchange in bodies of carp belonging to different age groups is shown. The paper proves the dependence of power exchange indices on the nature of the toxiccant (herbicides, phenol, lead cations) in carp's organism. Two-year-old carp's state under toxic influence is given a comprehensive estimation. The paper focuses on age peculiarities of forming Cyprinus carpio L.'s adaptation to low temerature and starvation. This-year's breed's adaptation is described as compensatory while the two-year-olds' one is identified as exploiting (offensive). Calcium cations are proved to stimulate the formation of adaptive reactions to herbicides in the organism of carp. The paper proves the influence of forag's aminoacide component of on biomass of young carp.
