Body lengths of fish in the samples, richness, diversity and composition of parasite infracommunities revealed significant local variations among trawls, while only the composition of the parasite fauna showed significant geographical variations among fishing zones. Parasite infracommunities in hosts from Caldera were the most different and were characterized by ectoparasites, whereas those from Talcahuano and Valdivia harboured more endoparasites, mostly digeneans. These results confirm the existence of 2 stocks on the Chilean coast. This study is also the first report of parasitism in anchovies from Valdivia. 2013 otro 0717-3326 https://www.redalyc.org/articulo.oa?id=47926382016 es http://www.redalyc.org/revista.oa?id=479 Revista de Biología Marina y Oceanografía application/pdf Universidad de Valparaíso Revista de Biología Marina y Oceanografía (Chile) Num.1 Vol.48 |
