This was mentioned waaaaay long ago, but Ohio talked about TU's advocation of eating wild salmon.
Someone correct me if I'm wrong, but the point of this is part of a pacific clean water act. If everyone gets salmon from farms, there is then no need to get them from the wild, which in turn give little financial motivation for any companies in the salmon buisness to protect the waters they live in. If you have all sold salmon being wild caught, people will need to protect the waters they swim in, in order to keep the business going. This, coupled with regulations for how much salmon can be harvested in a season, will both maintain a sustainable wild salmon population, and keep their waters free of pollution/developement. Granted this will cause the price of salmon to shoot up, but if you want to keep certain natural resources, you gotta learn to sacrifice.
The same motto could be applied to catch and release regs. Harvesting trout obviously makes more sense as a fundamental reason to fish. However, with the dense population of anglers who surround many of the states best fisheries, if you did not have catch and release regs, they would become graveyards. So, you gotta sacrifice some if you want fish to live in those places.
Personally, even though this would be economical suicide for the PFBC, I would like to see no stocking of any PA streams, and have statewide regulations of single hook, barbless ALO, and an increase in the promotion of wild trout populations. I do understand that this is a completely illogical idea, its just a fantasy of mine, so please don't spend 100 posts talking about how unrealistic it is.
