The natural habitat of redclaw generally
consists of permanent water-holes in the upper
reaches of rivers, with static or slow
water flow. Where crayfish are relatively
abundant, there are usually considerable
amounts of fallen timber in the water. In
addition or alternatively, dense beds of
macrophytes may occur where redclaw
abundance is high. The correlation of redclaw
abundance and the physically complex
environment afforded by the fallen timber
or macrophytes suggests that redclaw may
benefit from shelter.
