Thanks for all the great replies. Our battle is not just with cormorants!

I've no desire to harm a heron, even if it were legal to do so. (Cormorants are a different matter.)

Took two steps today to help with situation. First, got 200 plants of four different varieties put into the pond. This will eventually give more shelter to the CNBG from predators. Second, moved my feeder to water's edge & tilted it up more. This should result in less feed near shore where GBH patrols, so fewer fish vulnerable to depredation.

Longer term, I may put up some sort of a fence around the feeder. Herons dislike landing in the water.
