There are a couple of ways for me to suggest what to do...one would be for you to pencil out a plan of boxes(squares), if that is what you want and size to get an idea for the fish:)Then I'd go fishing for fishes...online, coloring books..conservation sites, etc. And make the fish you want w/different fabrics and wonder under w/a straight stich(or satin stitch, etc) on each fish. Then put then in the designated squares. You would make the fish to fit whatever size you came up with. I'm sure there are favorite fish of his:)Or you can put a fish in the center...whatever size you decide w/colors of the fish all the way around him in quilt blocks. Just some thought on this:)Skeat (or use actual fishing pictures of caught fish from him for your blocks:)
