“…The natural range of pumpkinseed is the freshwater reservoirs of North America from the Great Lakes to Florida [2,3,4,5]. In the Zaporizhzhia (Dnipro) reservoir the pumpkinseed is known as the alien species [6]. To date, this species has become well acclimated and has expanded its habitat in the reservoirs of Dnipropetrovsk region [7,8].…”

The article presents the results of studies physiology of nutrition of juveniles individuals of pumpkinseed Lepomis gibbosus (Linnaeus, 1758) from the Zaporizhzhia (Dnipro) reservoir. histological structure, morphometric parameters of digestive system and nutrition biology were investigated. The material for work were collected during scientific research in June-July 2016–2017. The ichthyological sampling was carried out in the Samara Bay of the Zaporizhzhia (Dnipro) reservoir. Researches of structure of digestive system were conducted using histological methods, researches of nutrition were conducted using ichthyological and hydrobiological methods The height of the intestinal epithelium of the pumpkinseed`s juveniles varies from 15.5 microns to 51.9 microns and on average is 32.59 ± 9.03 microns, the area of secretory goblet cells of the intestine reaches 198.61 ± 36.55 μm2. It was revealed that the pumkinseed’s juveniles only feed on phytoplankton. Research results can be useful for further study on the fish nutrition, especially sexual matured. Also, nutrition studies can help to find biomeliorative methods to combat the pumpkinseed, because the species is in competition with industrially valuable species of fish for fodder.

“…[1,4,6,8] Pumpkinseed Lepomis gibbosus (1758) is a member of the sunfish (Centrarchidae) family, perciformes (Perciformes) order. Today, the pumpkinseed is one of the most common alien species in the Zaporizhzhia (Dnipro) reservoir basin, which rapidly increases its number and biomass [9]. In Zaporizhzhia (Dnipro) reservoir the species began to be found massively in 2002, and since 2017 it appeared in the heat sink of the Zaporizhzhya NPP [10], indicating the rapid spread of this species in all types of reservoirs [11,12], including natural to technical reservoirs with different degrees of radioactive loading.…”

The article presents the results of studies on the content of artificial (137Cs, 90Sr) and natural radionuclides (226Ra, 232Th, 40K) in tissues and organs of various individuals of pumpkinseed Lepomisgibbosus (Linnaeus, 1758) from the Zaporizhzhia (Dnipro) reservoir. It has been revealed that in the bones of sexually mature pumpkinseed females, the content of radionuclides 137Cs and90Sr is 24.7% and 28.6% less, respectively, than in the bones of males. Summing up the materials of radioecological studies of 2017–2018, the following sequence of tissues and organs of the pumpkinseed by the ability to accumulate radionuclides was obtained: bone> muscle> scales> gills. Research results can be useful for further study on the fish radiation load in the basins of the Dnipro River and during monitoring radioecological research. It was determined that the content of radionuclides in the pumpkinseed muscles did not exceed the permissible levels of radionuclide content for fish as a food product (permissible levels of radionuclide content for 137Cs – 150 Bq/kg, 90Sr – 35 Bq/kg).
