raw fish

Raw fish can be harvested from water. They can be used to refill a small amount of health instantly. In order to catch raw fish, mine one of the dark spots that can be found moving around in water bodies. Each dark spot yields 5 fish when mined. Fish can be also collected via construction robots, by marking a water area that contains fish with a deconstruction planner.

Raw fish is used to heal by clicking on the character or anywhere else in the world with the fish in the cursor. They heal 80 HP each and have a short cooldown for reuse, limiting the amount of incoming DPS that fish healing can absorb. Using a fish produces a munching sound.

Using landfill on water where a fish is swimming will "destroy" the fish. Fish can be shot and killed via pistol or submachine gun, flamethrower, tesla gun, and also by explosions, but are immune to any kind of shotgun or railgun fire. Shooting fish does not grant any fish items.

Fish are created in water when the world is generated and do not despawn or respawn. While inserters can remove fish from the water, they cannot put them back. The player can manually return fish to the water in stacks of 5, which resets both the quality and freshness of the fish.
