Ihtiofauna lacului de acumulare Dubăsari – compoziția, dinamica modificărilor stării cantitative și calitative

This paper represents the results of the researches of the ichthyofauna of the Dubăsari accumulation lake in successional aspect. It was found that due to the influence of anthropogenic factors in the last 5-6 decades (construction of Naslavcea and Novodnestrovsc dams, excavation of sand and river gravel from the minor riverbed, use of water for various purposes, accidental, biological and thermal pollution, damage and destruction of substrate of reproduction for lithophilic and phytophilic species, etc.) in the ichthyofauna of the middle course of the Dniester River (Naslavcea – Camenca village) and the Dubasari accumulation lake have undergone essential changes, reflecting the structural and functional status of the fish populations, the growth rate, sexual maturation, prolificacy and the annual sexual cycle. Apart from these factors that have influenced and continue to negatively influence the fishery resources in the Dubasari reservoir, the factor of their poor management also persists in the last 25 years.
