I attached a few photos from this past weekend. We did use the cast net, I forgot about that, we used it three times and caught this bass {moderator edit: the bass was by-catch and after the photograph was released unharmed: personal communication from the original poster} and it then spit up a small hognose
I've also been finding these little round guys, finally got around to looking it up and they are called Water Penny, pretty neat.
