I have always had best luck with silver but go tired of them being stolen so I painted the rest i had black and my catch ratio went way down... JMO
The lower catch rate may be related to chemical residue from the paint.
Try glass minnow traps, they're a bit pricey but they'll out fish the wire traps 5 to 1. I have trapped river shiners for over 40yrs. and have tried everything but the glass traps out shine anything on the market.
How often do you guys go back to check your traps?
