Fishing nets!

How about adding fishnets that can be crafted using string and sticks. You could set the net and return to it in a day or two, similar to waiting for crops to mature. You could collect 1-5 items per cast. This would enable the player to gain fish and assorted items while doing other things in the game. You would still need the fishing pole when the player wants a larger amount of fish. The net could break after a certain number of uses like other tools in the game.
