Spoiled Fish is an item introduced in the Shipwrecked DLC. Dead Dogfish and Dead Swordfish will turn in to Spoiled Fish instead of Rot if left to spoil. It is also possible to pick one up in a Trawl Net. Spoiled Fish can be Hammered to get 2 Bone Shards.
- Bone Shards stack up to 20, but Spoiled Fish stack up to 40 and each can be hammered for two Bone Shards. This makes it more space efficient to store Spoiled Fish.
- Hammering the Spoiled Fish in the Inventory will make the Fish disappear and not give any Bone Shards. Placing the Fish on the ground and hammering it there works fine.
