Frequent haplotypes of caged Caligus rogercresseyi in the austral south of Chile: The result of a long term serial passage experiment?

The use of haplotypes described in this study, especially A and B, in experiments of drug resistance in this parasite is relevant compared to the use of unknown haplotypes. This could be important for determining the kind of drugs used against this parasite as well as in the study of resistance mechanisms to the chemotherapeutic substances used in Chilean aquaculture.
