| Impact Description | An observational field study using an underwater video camera documented competitive interactions between the yabby (Cherax destructor) and the endangered Fitzroy Falls spiny crayfish (Euastacus dharawalus). The yabby displayed increased aggression compared to the spiny crayfish. Findings suggest the yabby poses a significant threat to this species through behavioral interactions. |
