I am no expert, they will be along shortly, but I think 4 hrs of fishing is not enough to tell what might be there. Larger fish can become smarter and harder to catch, so continue on your gathering information, have some fun doing that. The pics of the fish in the trap look like bg, but they could be res, or hbg or some other type of sunfish or brim as we call them down here. Need better pics up close and personal. But the trap sample looks encouraging when it comes to forage fish for your lmb. And if you continue to catch only the size of lmb you reported, you could have to many lmb and a shortage of forage. Keep sampling
Have some fun doing it
