General Tips
Look for Silver Redhorse in areas with a moderate to slow current. A good place to start would be around rocks, logs, or other obstructions, where these fish like to gather.
How to Catch
Preferred bait or lures
As bottom feeders, Silver Redhorse is attracted to worms and other small, soft-bodied invertebrates. Some successful anglers have also reported using corn as bait.
Fishing techniques
Given their habitat preferences, bottom fishing techniques are most effective for catching Silver Redhorse. Fly fishing can also be effective, as can drift fishing with live bait.
Identification Guide
The Silver Redhorse can be identified by its silvery colour, large size, and the distinctive shape of its lips. Its dorsal fin is typically straight or slightly convex, with a red hue. It is very similar to the Golden Redhorse, though the silver appearance can help differentiate the two.
Additional Information
Unlike many fish species, Silver Redhorse are largely solitary in nature and not known for group feeding or traveling in schools. They are preyed upon by larger fish, birds, and human activity through fishing and habitat disruption.
The Silver Redhorse holds some cultural significance to native communities who have fished it for centuries. To some, it is a sign of the changing seasons as it migrates in the spring and fall.
