I have no problems with culling of any animals if it serves a purpose. But if the only study conducted suggests a cull would make it worse then why would you possible consider doing it based on popular hearsay that says the opposite! I'm greatly in favor of a cull of the Scottish midge or the giant mossies that feasted on my legs the other week. As for sport angling, its so heavily controlled these days I think of it just like farming, many of the fish wouldn't even be there if they were not added by local angling clubs.
