snrub - Visualize a B trap as half of a cloverleaf trap. Maybe not the right tool for catching catfish. My Grampa Wilkie used a lot of slat traps when he fished commercially on the Missouri River. He built his own, but they were very similar to this one: https://www.netsandmore.com/products/fishing-accessories/slat-traps
esshup - Heron strike seems likely. There are several of those nasty things that pond hop the neighborhood every day. Mrs. Augie likes them. She thinks they're "pretty", and has made it clear to me that if anything bad happens to one of them, and she finds out about it, somebody is gonna be in big trouble, so they get a pass.
