Abstract

I n t e r n a t i o n a l J o u r n a l o f O c e a n o g r a p h y a n d H y d r o b i o l o g y U-test, p<0.02). The number of parasites was found to increase with the fish length. Although in both and C. inermis, the anisakids were more frequent in males (prevalence of 52.17 and 67.76%, respectively) than in females (prevalence of 35.39 and 42.86%, respectively), differences between the sexes in the infestation level in the two species were not significant (Mann-Whitney U-test, P= 0.09 and P=0.23, respectively). The molecular method applied (PCF-RFLP) allows to identify all the nematodes in both examined fish species as C. osculatum baicalensis.
