Nematodes parásitos como indicadores biológicos en las especies Macruronus magellanicus y Merluccius hubbsi (Pisces, Gadiformes)
Parasites nematodes as biological tags of Macruronus magellanicus (longtail hake) and Merluccius hubbsi (hake) colleted between 34°- 55°S in the SW Atlantic were studied. Adult specimens of Hysterothylacium aduncum, Ascarophis marina and Ichthytofilaria argentinensis, and the third-stage specimens of H. aduncum, Anisakis simplex and Contracaecum aduncum were described. Histological studies showed that I. argentinensis provokes tissue reactions in the swim bladder of M. hubbsi. A wide distributional range of species can be represented by many fish populations or fishing stocks. As these can overlap in space, the proper identification of stocks is necessary for fisheries management. The parasitologic method is one currently used to determine stocks. Species that could be used as biological indicators were selected. Average abundance values of L for Anisakis simplex and Hysterothylacium aduncum were estimated. Different areas of abundance were recognized.
