Between February 1996 and January 2000, parasitological examination of Scomber scombrus (n = 447), Trachurus trachurus (n = 175), Sardina pilchardus (n = 160) and Engraulis encrasicolus (n = 153) from the fishing-ground of Tarragona (NE Spain) were made for anisakids. Three anisakid species (Anisakis larva type I sensu Berland, 1961, Contracaecum sp. and Hysterothylacium aduncum) were morphologically identified. The prevalence of Anisakis larva type I sensu Berland (1961) ranged from 11.0 % (S. scombrus) and 2.6 % (T. trachurus) to 0.0 % (S. pilchardus and E. encrasicolus). The prevalence of H. aduncum in S. scombrus was 1.1 % . The prevalence of Contracaecum sp. was 2.0 % in S. scombrus, and 0.7 % in T. trachurus respectively. There was a positive and significant correlation between the host length and the number of Anisakis larva type I sensu Berland, 1961 found in S. scombrus.
