Abstract
Introduction. There have been given results of the assessment of quality and safety of hydrobionts exampled by fishes as main objects of amateurish fishing in water bodies of the Central Feddral District of the Russian Federation. Fishery water bodies on this territory are exposed to anthropogenic impacts and lead in the concerning volume of polluted effluent discharge in Russia. The purpose of this study is to assess the quality and safety of hydrobionts on the example of fish - the main objects of amateur fishing in the reservoirs of the Central District of the Russian Federation. Material and methods. Fish catching was carried out in the summer-autumn period in 2013-2017. The volume of the survey sample was about 1500 fishes. The species composition of helminths in 15 fish species from three families Cyprinidae, Percidae and pike (Esocidae)is was determined by parasitological examination. The safety of fish was evaluated using parasitological and toxicological methods. Results. Fish from water bodies of the Lipetsk, Tambov, Belgorod, Bryansk and Tver areas has been ascertained to be facultatively available for human consumption. Clinical signs of the disease were observed in fish infected with metacercariae trematodes (posthodiplostomum and apophallus) in the form of black spots on the body. Among the detected worms, 2 species can be potentially dangerous for warm-blooded animals and humans - Pseudamphistomum truncatum (Trematoda: Opisthorchidae) and Apophallus muehlingi (Trematoda: Heterophyidae). Analysis of fish contamination with heavy metals showed excess of the permissible cadmium content in fish tissues. Conclusion. The conducted research showed the urgency and social significance of studies on monitoring for water objects and the need to implement the preventive work with the population in such a densely populated part of the Russian Federation as the Central Federal District.

Summary
Головина Н.А., Романова Н.Н., Головин П.П., Здрок А.В. Ухудшение экологического и санитарного состояния водоёмов может привести к снижению качества и безопасности водных биологических ресурсов (гидробионтов). Цель исследования – оценить качество и безопасность гидробионтов на примере рыб – основных объектов любительского лова в водоёмах Центрального округа РФ. Проведённые исследования показали актуальность и социальную значимость мониторинговых исследований водных объектов и необходимость проведения профилактической работы с населением в такой густонаселённой части РФ, как Центральный федеральный округ.
