Abstract

Nematodes of the Anisakidae family were studied in Sardinella aurita and Mugil curema caught in Venezuelan coastal waters and sold in Cumaná’s main market in Sucre state, Venezuela. Fifty fish of each species were analyzed, examined, dissected and their internal cavities, cephalic organs, abdominal trunk and caudal regions wereinspected. They were also debrided, and muscles dissected in search of nematodes in their third larval stage (L3) through simple visual examination. Detected nematode parasites were mechanically extracted from the organs and tissues for identification and classification at the genus level. The M. curema species was the only fish found to be infected with parasites. Distinct parasitic species were observed in 48/50 (96%) of the M. curema specimens analyzed. The prevalence of helminths in these specimens included nematodes of the Anisakidae family, Acanthocephala and other unidentified parasites. Of the total specimens examined, the parasites were distributed as follows: the Anisakidae family (66%) (33/50), Pseudoterranova sp. (44%) (22/50), Anisakis sp. (32%) (16/50) Contracaecum sp. (12%) (6/50). These parasites were mainly located encysted in the caudal kidney (55.09%), the liver (28.81%), and the digestive viscera (inside the gut) (16.10%). This shows the existing human risk in acquiring anisakidosis larvae parasitism, depending mainly on the cultural habits of consuming raw or undercooked fish.
