Maybe you can find a net with mesh size ~ 6"? I'm not sure if nylon nets in such size are often found but at least other material nets for different purposes have been seen. Sure, the bigger mesh size, the greater diameter of line will be and cormorants may avoid that.

Almost forgot to say that any gill nets can't be left in the water for a long time because they soon get covered by algae. In summer it might happen in a week. Then you have to take it out and clean. Probably the easiest way is to wash it with a pressure washer.
