Your best bet, in my opinion, is to get the $12 Texas Cormorant permit and then protect your interests. I promise you, they will find your fish and they will eliminate them....if left to their desires. Like I said, once they find you and tell all their friends, it won't take long to clean you out. They eat about 2 pounds of fish per day per bird. Do the math and see what I mean.
I've tried fake owls, cars, scare crows, recordings, etc. The permit with enforcement is the best solution....or you can let nature take its course and have a fishless pond.
Another word on this subject...those who do not have this problem are sometimes sympathetic to protecting the water turkey. I can understand that thinking....they just haven't seen the complete destruction these birds can cause to the fish owner.
