- Due to the emergence of new species in ichthyofauna of the Zaporizke reservoir, there was a need to study their biology, ecology and patterns of their distribution. Biological invasions of new species of fish can have diverse effects both within aboriginal populations and within the entire ecosystem. The pumpkinseed Lepomis gibbosus (Linnaeus, 1758) is one of the most common alien species in the Zaporizke reservoir, which has already adapted to the new environment and quickly develops the reservoirs of the region and increases its number. In addition, this species has a wide range of nutrients and can compete for feed resources with other species of fish. The purpose of the work: to study the biological and ecological parameters of the pumpkinseed, the basic laws of its physiology. The paper describes the results of fish morphological studies, estimation of the number and biomass of young fish, determines the morphometric parameters of peripheral blood, determines fertility indexes and features of the course of oogenesis. The paper presents preliminary results of the assessment of the consequences of the invasion of this species in the basin of the Zaporizke Reservoir.
