Краткое описание

The investigations concern the structural and functional characteristics of Moina macrocopa population and its energetic status in different phases of cumulative culture growth with respect to changes in hydrochemical parameters of the cultivation medium. In the phase of maximal numbers and biomass the substantial alterations in population structure were observed: increasing of numbers of sterile and mictic females and reduction of the share of the amictic individuals. Decrease of energy resources in a crustacean organism, such as high-energy phosphate compounds (ATP, ADP, AMP) and total contents of proteins and lipids were registered. The issue concerning correlation between parameters of the functional state of M. macrocopa and water quality characteristics (the fall of the dissolved oxygen level, an increase of organic and nitrogen compounds contents) during culture growth is discussed.
