Looks like a great day in the life of a fisherman.
I applaud your son's practice of catch and release. Thats what I do too. It's been 12 years or so since I've kept a speckled trout, (Different kind of trout, of coarse, salt water version of a trout).
This one caught from my Hobie Outback. I do all I can to keep from touching the fish. De-hook while in the net and release by lowering the net into the water.
Thank You Jack!!
When I used to fish, I usually used a net, however I believe most nets remove more of the protective Slime from a fish than a bare hand does.
