Bathymetric food habit changes in the antarctic fish, Notothenia gibberifrons Lönnberg. (Pisces: Nototheniidae).
The dietary composition of the antarctic fish Notothenia gibberifrons Lönnberg in a depth gradient was studied, from sea level until 200 meters in South Bay, Doumer Island, West Antarctic. The diet of this species varied across the depth gradient. Stomachs from specimens captured between the surface...
