Resumen:
No previous studies were carried out on aspects of the helminth
assemblages of Seriolella porosa. The present study aims to analyze the
metazoan parasite of S. porosa and establish the relationship between the
parasitic variations and both fish size and sex. Atotal of 101 specimens of S.
porosa from San Matías Gulf, Argentina were examined between September and
October 2006. Thirteen species were reported with a total of 3366 parasites.
Lecithocladium cristatum was the most prevalent, dominant and abundant species.
The average species richness was 3.2 ± 1.20. The evenness showed an inverse
correlation with the total number of parasites and did not reveal differences
between host sexes. None of the parasite species showed interspecific
associations with each other. The average richness of the infracommunity was
significantly less than the component community. The helminth community of the
silver warehou shows Little diversity with many satellite species and only two
core species (Anisakis sp. and L. cristatum). Further studies, using parasites
as stock indicators, would indicate whether the San Matías population
represents a reproductive aggregation that penetrates the gulf seasonally in
winter or whether it is a permanent stock isolated from the continental shelf.
