Alright guys, I'll be the first to admit I am not very multifaceted fisherman. With new electronics I have been finding fish like never before. I then struggle to catch them. So last weekend I found fish like this

I used a 3/8oz jig head to drop a grub body down to what appeared to be the predator fish on the right side of the pic. I had no takers. How do you guy approach the situation when you find something like in that screenshot? Probably need to get a better fisherman than I in the boat so they can teach me some things.
