First data on the daily food consumption by Antarctic fish Trematomus hansoni (Actinopterygii: Perciformes: Nototheniidae) in captivity

In this study, we present first observations on the feeding behaviour of an Antarctic notothenioid fish, the striped rockcod, Trematomus hansoni Boulenger, 1902. During 13 days of feeding experiment onboard RV Polarstern, the striped rockcod consumed an average of 1.0% BM · day–1 of Loligo reynaudii...
