Biome Specific Fishing

I don't know if this is a good idea, but I think it would be cool if biomes influenced what loot drops one could get from fishing. For example, the river would yield more salmon than any other thing because that is what lives in the river. You would have more chance of getting junk, specifically lily pads from a swamp, tropical fish and nautilus shells from a warm ocean, tropical fish in a jungle, and I think it would be cool if there was a slightly increased chance of finding treasure if fishing in a mooshroom biome. That is all! :)
