Cool pics! Yellow perch are schoolers(even more so as juveniles) so it makes sense they can gobble up a bunch all at once. Most predatory gamefish like bass, pickerel, trout tend to be solitary feeders which may help them survive being eaten by birds en masse.

Santee Lakes in San Diego has Cormorant problems They tried boomers, put in Catfish instead of Trout , even larger Trout with limited success. Finally they got a kill permit and that stopped it for a while.
