From my experience I have not seen where fertile waters with 18" of green visibility made any difference in discouraging the cormorants. This year my water is at 6' of clarity and I have seen fewer or maybe the same numbers of the dam birds. I'm leaning toward clear water might be better than fertile waters. If fish see the bird or the birds shadow they most likely will dart away like they do when a human approaches them.
Shad are a fish that they will attack, I've seen it at my pond where they drove the shad back into a corner. They killed off a lot (hundreds) of the 4" TFS and did not even eat them.
Right now, I have an Osprey that loves my pond and feeds there daily I don't deter him but I see him fly off most everyday with a 5 to 7" cnbg. Now, multiply that by the number of days he has been there. He has been there for several months now.

Do not judge me by the politicians in my City, State or Federal Government.
