Comparison of the parasite community of two notothens, Notothenia rossiiand N. coriiceps(Pisces: Nototheniidae), from King George Island, Antarctica
Abstract In this study, we analysed and compared the whole parasite community from the fish Notothenia rossii and Notothenia coriiceps collected from Fildes Bay at King George Island, Antarctica, during January–February 2017 in a field campaign supported by the Chilean Antarctic Institute.
