[Peter-the-Great Gulf fishes are a source of human invasion of the nematode Anisakis simplex (the family Anisakidae)].
The paper presents the results of the rate of infection with the nematode Anisakis simplex in Peter-the-Great gulf fishes that are a source of human invasion. Five of 19 fish types were found to be nematode-free, and the extensiveness and intensity of invasion were observed in Siberian salmons (Oncorhynchus keta) (61% and 2-700 worms, respectively), Alaska pollacks (Theragra chalcogramma) (75.7% and 1-31 worms), and brown rock trouts (Hexagrammos octogrammus) (100% and 1-60 worms). Autopsy showed that the distribution of larvae was ambiguous in different fish species. Data on the survival of Anisakis were also obtained under experimental conditions. The nematodes were ascertained to die at -8 degrees C at the moment of complete fish freezing. Anisakis may be alive in the unfrozen fish for more than 40 days. The death of worms in the salted fish occurs within 3-8 days only when 6-10/1000 concentrations of NaCl salts are achieved at the sites of worms.
