Abstract
The diet and prey selectivity of Myctophum asperum were examined from the Perth Canyon (Western Australia). Calanoid copepods were consumed by 83% of the M. asperum examined and constituted 39% of the total number of prey items. Larger adult euphausiids were consumed by 48% of M. asperum and constituted 15% of the total number of prey items. Prey selectivity was assessed using Chesson’s Index and calanoids were not positively selected with M. asperum showing a preference for euphausiids and neutrally selecting most other zooplankton. This study contributes to understanding of the pelagic food web of the Perth Canyon Marine Park.
