Here's a question I've been chewing on for the past two weeks. Ever since early spring I have been hammering the channel cats in my river using large 4-6" sucker minnows. For the past two weeks though, it has been very hit and miss. I'll get a few large strikes, enough to bite the minnow in half headfirst, but they never come back for the rest. I'm wondering if these are the fish I have caught in the past and they've wised up? I never keep the cats I catch, and they get tossed back after a kiss on their nasty lips and maybe a quick picture. Anybody have any theories? They should be in full spawn mode right now I assume, so I would have guessed the fishing would be better now than even in the past so far this year. 1) Is it possible for them to be wising up, especially if I catch and release and those fish still patrol the same waters? 2) Should I change my bait, at least throw an experimental bait out as well? Any theories or advice would be greatly appreciated.
