How many trout do these diving birds really eat?

I caught a few largies in colonial last yr, about 2 lbs each, on white spinnerbaits ripped along the bank by the boat launch. There was a bunch elsewhere cruising around but wouldn't take.

You are correct on the number of cormorants over there. For a lake of that size, it has easily got to be the most densely populated with those birds. They'll wipe out half of the stocked fish by tomorrow...if not more.
