On survival of the larvae of marine parasitic nematode Anisakis simplex sensu lato (Rudolphi, 1809) in the fresh waters
Survival of the larvae of marine parasitic nematode Anisakis simplex sensu lato (Rudolphi, 1809) in the fresh waters was monitored. In total, 37 live larvae of A. simplex s.l. were sampled from charr Salvelinus malma caught in the lower reaches of the Kamchatka River. The larvae were kept in the fre...
