Anisakis spp. burden in Trachurus trachurus

Anisakis is a parasite of marine mammals that uses a great number of fish species as intermediate or paratenic hosts. It is common in commercially important marine fishes and its presence is of great concern for both human health and economic reasons. Horse mackerels (Trachurus trachurus) originated from the Northern Aegean Sea were examined for the presence of Anisakis spp. larvae. The prevalence of Anisakis spp. was found 98.8 %. The number of parasites was significantly related to the host’s length but was not related to the fish gender. The month of sampling affected the size of the fishes and consequently the number of parasites. The length of larvae was not related to the host’s length. The present study resulted in the design of a prediction model for the number of existing parasites in the fish by measuring only its Fixed Length.
