【 摘 要 】

Abundance and biomass of the invasive thiarid snails such asMelanoides tuberculata(Müller, 1774) andTarebia granifera(Lamarck, 1822) were studied in conditions of the cooling pond of Zaporizka NPP (Nuclear Power Plant) in autumn, 2017. The total biomass ofM. tuberculataandT. graniferaaveraged 12.39 g/m 2in the cooling pond and 177.69 g/m 2in the upstream channel. In order to resolve the problem of snail foulings, an attempt was undertaken by means of introduction of such snail-feeding predatory species as black carp,Mylopharyngodon piceus(Richardson, 1846) andAnentome helena(von dem Busch, 1847). As shown by the aquarium experiment, the level of thiarids consumption by the hostile snail declines in the presence of tilapiaOreochromis mossambicus(Peters, 1852) living in Zaporizka NPP’ сooling pond, as its fecal pellets are the additional food forA. helena . Taking into account the literature data, results of the model experiment and especial conditions of constructions and water bodies within the thermal structure of NPP, the introduction of theA. helenasnail was proposed for biological control of the invasive species ( M. tuberculataandT. granifera ) primarily inside of pipes, and the fish predatory species was preferably provided for the cooling pond and upstream channel of Zaporizka Nuclear Power Plant.
