Fishing slows for me on both species.Channel cats do seem to be the toughest to catch during the spawn,but usually get a few by fishing as tight to the nest as possible.I will cast my bait as close to a snag as I can,then let some line out so that the bait ends up way up inside the snag.The bite is very light.You have to pay very close attention to your line and I keep a finger on it.If I feel any thing I set the hook.They don’t grab the bait and run but I suspect that they pick up the bait and place it out side the nest.
Live bait can be better at this time but its tough not get hung up with a lot of line out and a lively bait swimming where ever it wants,so I keep to cut bait when the snag is really thick.
I typicaly find these cats to be better than average size and yes…they are in spawn color and beat up.
For flatheads,buisness as usuall,except like others said I move more often.
