Recorded from cold to relatively cool, clear water in flowing creeks to large rivers (1.0-20.0 m average width), usually in shallow (0.1-0.4 m average depth), fast-flowing and high energy riffles and runs 10c), though juveniles have been recorded moving upstream through slow water along the shallow edges of pools. Substrate in riffles and runs consists predominantly of a complex of abundant cobbles and pebbles, with smaller amounts of bedrock, boulder, gravel and coarse sand. Fish are typically found within the diverse substrate, either
amongst or under rocks on the stream bed, or deeper in the interstitial spaces of the substratum. Usually not associated with aquatic vegetation, but have been found amongst small and large timber debris. |
