Abstract
   The aim of our investigation was to assess the fish health condition from wild population from the Prut River in order to evaluate the quality of its aquatic environment conditions. Analysed fish species were: Cyprinus carpio, Silurus glanis, Stizostedion lucioperca, Abramis brama. Parasitological analyses were carried out in the Research Centre MoRAS-UDJ Galati (http://moras.ugal.ro). Parasitological investigations were performed on fresh samples by classic methods and the obtained results were expressed in grades of extensity and intensity. In the analysed fish, 10 parasitic species were identified belonging to 7 systematic groups: Mycophyta, Monogenea, Trematoda, Cestoda, Nematoda, Acanthocephala, Crustacea. The extensity of the parasitosis varied among examined fish species, as the following Abramis brama ˃ Silurus glanis ˃ Cyprinus carpio ˃ Stizostedion lucioperca. The most frequently found helminths were monogeneans and nematodes. Although a higher number of parasites has been identified in the analysed fish, the parasitic intensity was lower.
