Fishing is possible in the game, but the only known type of fishing yet discovered is spear fishing.

If any of you have any experience at spear fishing in real life, you will undoubtedly notice that in real spear fishing, you need to stand perfectly still until a fish comes close, but in the game, it only works if you walk around, wading through the water. Sorry about that. It was just easier to program that way. We plan to fix it at some point to make it more realistic.
