CANETE, Juan I et al. Ocular Parasitism in Patagonotothen Cornucola (Pisces: Nototheniidae) by a Siphonostomatoid Copepod (Pennellidae) at the Magallanes Region, Chile. Anales Instituto Patagonia (Chile) [online]. 2013, vol.41, n.2, pp.65-74. ISSN 0718-686X.

Penellidae copepods possess a body of saccular shape and are found almost exclusively in the eyes of some demersal fishes (e.g. flat-fish). This report deals with the presence of a parasitic, siphonostomatoid copepod in the eyes of Patagonotothen cornucola at Porvenir Bay, Strait of Magellan, Chile shallow areas (< 1 m depth) (53°18’30’ S) (70°23’00’ W), giving some details on the level of prevalence (N = 131 individuals, < 60 mm TL; 11.5% parasitized). Additionally, is detected this ecological relationship in other two Magellan locations.

Keywords : Parasitism; Nototheniidae; Phrixocephalus; Copepod; Subantarctic megafauna.
