cant you catch them real easy by when they are getting there young to the surface you just throw topwater and they get pissed off and hit it no matter what?
any thing top water like especially gurgling spinner baits. or something easily visible from under water like crank baits. where you gonna find snake heads in MO?
I have located a canal in Broward County that has a mom SH with tons of Babies. She will hit anything that goes in the water..I mean anything. Yeah, get a cast net and you would have like 15 at a time in this spot. It is like the gold mine of SHs.
