Parasitofauna y alimentación de notothenia c.f. angustata Hutton 1875 pisces notoheniidae en el intermareal de dos localidades del Golfo de Arauco, Chile / Parasite fauna and food contents of notothenia c.f. angustata Hutton 1875 pisces nototheniidae from 2 intertidal localities of the Golfo de Arauco, Chile

ABSTRACT

We studied the parasite fauna and food contents of 38 juvenile of notothenia c.f. angustata specimens captured in the intertidal of Island Santa María and Maule, in the Arauco Gulf, Chile. Trophic habits of notothenia c.f. angustata were not different between localities, which was mainly algae. A total 11 parasitic taxa among were found with the digenean lecitasther macrocotyle, cestode larvae tetraphyllidea and diphyllidea and nematode ascarophis sp. being the dominant taxa. The abundance of parasites was similar in the two localities, although the infracommunity richness was higher in fish from Maule. The most abundant parasite was L. macrocotyle in hosts from Isla Santa María, while those from Maule they were the diphyllidea larvae and nematodes ascarophis sp. The body length of the hosts was not a good predictor of the variations in abundance and richness at infracommunities, probably because of the early ontogenetic stage of fishes
