In the Volga-Caspian region there is abundant variety of parasitic species from different systematic groups. Some species ofparasites can be pathogenic not only for fish, but also for human that is why studies on the infection rate of commercial fish species by agents of are very topical for today. The work presents materials on invasiveness by the sanitary-significant helminthes of sheat fish, pike-perch, perch, pike, bream, Caspian roach, red-eye, sabrefish, silver bream, anchovy and ordinary kilka, herring, Caspian shad, black-backed shad. In parasite cenoses of all studied representatives of ichthyofauna there were from one to four species of helminthes which are pathogenic for human and warm-blooded animals. The obtained data indicate to the functioning and active circulation of natural foci of invasion ofAnisacidosis, Eustrongylidosis, apophallosis, rossicotremosis, corynosomosis, opisthorchiasis and pseudamphistomosis in the delta and avan-delta of the Volga River, which, in turn, points to the sanitary trouble of the Volga Caspian region. |
