If all you're concerned with is catching fish and not killing fish (which a great thing to teach 'em when they're young; not everything you catch has to be killed), find a nice calm spot on the sound and catch sole. You even have the chance of getting cabazon or sand shark. Teach him now that fishing can be for fun and sport, not just to kill something. However, if you do get a nice cabazon, take it home and explain to the little guy why you chose that fish over the others.

Start 'em young to respect the sport and odds are he won't grow into a meat-fisher.

Just my dollar-two-ninety-eight worth.
