its a bad system they need to completely rethink. Also tiering the fish to bait from the previous biome is a horrible, horrible design decision, ESPECIALLY since there's basically no benefit to those fish until you get to the angler fish for fish n bread, as you make fish wraps with any gutted fish regardless of what you caught, no special recipes with any of the fish except the very last one you can catch. It's not interesting and not worth the hassle.

Also, it can be circumvented entirely by just making fish traps in the Mistlands, there, days of fishing for better bait over and over saved. :D Please think this over Irongate, if you're going to put fishing in the game it needs to be meaningful.
