| Impact Description | Contest experiments between the yabby (Cherax destructor) and the Fitzroy Falls spiny crayfish (Euastacus dharawalus) found that the spiny crayfish was frequently more aggressive and less submissive than the yabby. However, the yabby spent significantly more time consuming food and may negatively impact the fitness of the Fitzroy Falls spiny crayfish through reduced access to resources. |
