It took a couple elections to ban gill netting here in Florida ,but in just a few years the fishing has improved for certain species dramatically.I'm a former commercial fisherman who has gillnetted and its a devasting fishery for just about everything you can imagine.Swordfish to mullet for their roe. A buyout of the boats and gear and some extra licencse fees for saltwater anglers were the ticket along wth an education of the voters on how the ocean and estuararies were getting hammered by a few.Manatees had nothing to with it, they are all over the place down here.
