    Trophic Ecology of Freshwater Fishes in Australia: Progress Report.

    Mark Kennard, Brad Pusey & Angela Arthington

Introduction

This report provides a brief outline of progress made to date on the CRCFE Scoping Study "Trophic Ecology of Freshwater Fishes in Australia". The objectives of the study were threefold:

1. To review available information on the diets of freshwater fishes throughout Australia (native and exotic species) and assess major sources of variation in fish diets associated with phylogenetic, ontogenetic, spatial and temporal factors.

2. To develop trophic classifications based on interspecific differences in diet, and evaluate in a quantitative manner sources of variation in fish assemblage trophic structure due to spatial and temporal factors.

3. To evaluate the potential for interaction between exotic and native fish species including identification of:
(i) exotic species demonstrated to prey directly on native fish, and

(ii) trophic groups and species with a high potential for competition for food resources with exotic species.
