At our pond we try to let our trout thrive on natural forage but it's just not enough for fast growth so we began supplementing their diet with Purina Aquamax 600. While it's not formulated strictly for trout Purina says you can use it for rainbows (I'd assume other species of trout as well). I've seen people that recommend using feed that is developed strictly for trout but the reason we've gone with the Aquamax is 1) The feed store down the road keeps it in stock and 2) A guy just down the road with a pond similar to ours uses it on his trout and grows trout in excess of 8lbs.

Just curious to see if anyone else on here has trout that they feed and what they feed them.
