Although there are no trout in our pond this year, I've had trout, browns, rainbows, and tigers all prey on the sunfish species in the pond. In fact I could throw the filleted carcasses of sunfish off the dock and have the trout dart in grabbing the remains as they sank. The tiger trout were particularly entertaincng to watch. As the rainbows would cruise through at high speed snatching a slowly sinking carcass, the tigers would grab a skeleton, come to a stop, and shake the sunfish remains, breaking it into smaller pieces as we've seen sharks do on the tube.
The trout loved Optimal BG pellets and ignored the living sunfish rising to the hand thrown Optimal and meal worms. However. the feeding sunfish would displace themselves several feet when each trout cruised through.
I can only imagine the trout were eating plenty of small sunfish.
