    A STUDY OF THE ANISAKID INFECTION IN THE CHILEAN HAKE, MERLUCCIUS-GAYI (GUICHENOT, 1848)
    (1985) CARVAJAL, J; CATTAN, PE
    Variation in the prevalence and intensity of infection of fishes by larval anisakids was examined in 360 hake (Meluccius gayi) caught off central Chile. Each month, from April 1979 to March 1980, 30 hake were taken from commercial catches and stored on ice for dissection and examination on arrival at port. Anisakis simplex was found in 90.5% of the hake and Phocanema spp. in 10.83%. No seasonal variation in the prevalence of A. simplex was observed in females.

    LARVAL ANISAKIDS AND OTHER HELMINTHS IN THE HAKE, MERLUCCIUS-GAYI (GUICHENOT) FROM CHILE
    (1979) CARVAJAL, J; CATTAN, PE; CASTILLO, C; SCHATTE, P
    A total of 120 hake (M. gayi) caught off central Chile were examined for helminth parasites. Sixty hake kept in ice from the catch of a trawler were examined on arrival at port, while the other 60 hake were dissected on board immediately after collection. Of the hake collected, 91% were infected with 1 or more species of the following helminths: trypanorhynch plerocerci of Grillotia dollfusi Carvajal, 1971; adult worms of the genus Clestobothrium; and larval nematodes of the genera Anisakis and Phocanema; Of the hake examined, 86% were infected with Anisakis sp. and 42.5% with Phocanema sp. Infection with larval nematodes increased with length of the fish and there was a greater incidence of infection among the females. There was a greater frequency of occurrence of the parasites in the viscera than in the musculature.
