Free: Contests & Raffles.
If they are with you they are participating.They get up early and endure long days on the water.My kids and wife and grown men for that matter catch and retain fish on my boat while they are sleeping.My favorite thing when my kids were young was to run three poles while they were below deck.When I would hear nosy,wanna be fish cop boaters mention my 3 poles,I would have the kids pop out.I miss those days!
I've been checked twice with my kids while fishing and asked the game warded.. You can legally assist but ultimately they have to hold the rod and reel at some point. He put an emphases on who is doing the "most" of the work while landing it not fighting it. I would hook the fish and hand them off to my youngest, he didn't have an issue with it as long as my limit wasn't retained. My other 2 kids where fishing unassisted.
