Abstract (EN): Horse mackerel (Trachurus trachurus) obtained monthly in a fish market of Oporto from October to August were surveyed for anisakid nematods (Nematoda: Anisakidae) in muscle and body cavity. The larval anisakids (Anisakis sp. L(3) and Hysterothylacium sp. L(3)) were found in body cavity but not in muscle. The infection levels of total larval anisakids (prevalence = 38.3 %; mean intensity 2.2; mean abundance 0.84), Anisakis sp. (prevalence 18.7 %; mean intensity 2.0; mean abundance = 0.37) and Hysterothylacium sp. (prevalence = 22.0 %; mean intensity = 2.0; mean abundance = 0.44) were low. Significant positive correlations were found between host length and Anisakis sp. occurrence, Anisakis sp. abundance, total larval anisakids occurrence and total larval anisakids abundance. The variation observed in infection levels throughout the year was discussed.
