The Fish Farm is a craftable Structure introduced in the Shipwrecked DLC. It is found in the Food Tab, requires a Science Machine to prototype, and 2 Silk, 2 Ropes and 4 Coconuts to craft. It needs to be stocked using Roe to produce either Tropical Fish, Purple Groupers, Pierrot Fish, or Neon Quattros.
Fish Farms can only contain only one kind of fish at a time and go through 3 different growth stages. Each harvest will yield exactly one fish. If the Fish Farm is harvested in the first stage, it will be empty again and require restocking with Roe. In each of the next stages, an additional fish can be harvested. If the player does not completely empty the farm, it will always keep producing the same kind of fish.
The amount of fish in a Fish Farm indicates its current growth stage, while the color of the fish on the small sign shows which kind of fish is produced.
Fish Farms can be "attacked" and plundered by Crocodogs, which will result in loss of fish stages (each producing a fish that will be eaten), until they are completely empty.[Verification Needed] Sea Walls can be used for protection.
- Fish Farms were added to the Shipwrecked DLC more than a year after its official completion in an unnamed beta update.
- The three fishes they can be obtained from Fish Farms are required to cook the Tropical Bouillabaisse.
