I feel for you. I am having the same problems. I think a late Spring and late fish spawn here in the north is part of the problem.They sure are persistent aren't they! At least they aren't eating your profits like me but I still feel for you. They are spearing my feed trained one to 5 pound bass in the head and leaving them injured as they are too big to eat. My bass are starting to bed which makes them vunerable.

I have put a "scarecrow" motion detecting water sprayer on my pier and I think that is keeping them off my pier. However they still come in and land on the shoreline. My dog is chasing them off when we see them, but we do not always see them as we may not be here or it is as early as 4:15 in the morning. I will now be getting up at that time and keeping an eye on the pond. Sure wish Indiana was on Daylight Savings Time and Eastern time so I would not have to get up so early!Next step is two monfilament fishing lines run from stakes that are parallel and one foot off the water along the shoreline. On the one side is the shore and the other side is too deep of water for them to wade. This may stop the waders.

You are aware that killing them is a federal violation if you are caught? They are a federally protected migratory bird. Some aquaculturist can get a permit to destroy them but it is hard to get. I'd love to blast those SOB's out of the water but would sure be caught! Good Luck!

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
