A free mod for Stardew Valley, by Goldenrevolver.

The Crab Pot Loot Has Quality And Bait Effects mod adds a few goodies for you to fish and enjoy. The first is the quality of the loot, based on your fishing skill and perks. The second is the bait, which can be normal quality, or you can use magic or even use wild bait. The third is the chance to get an extra bonus for the type of pot you are using. For example, if you are using a crab pot, you can get an extra bonus for the type of bait you are using. It’s not going to change your gameplay, but it’s going to make the game a little more fun for you.
