Living with the river
Water & habitat
Rocky habitat and nearby cover are useful context for this species. A flow reading measures water passing a station, not the amount of shelter or fish in a particular pool.
Seasonal life
Males construct and defend gravel nests in spring and summer.
Before you go
Do not confuse rock bass with every fish called 'rockfish'; that common name can refer to other species.
Use the linked agencies and the relevant river guide for current regulations, closures and consumption advisories. A species profile is not a fishing license or a statement that harvest is allowed.
