Bone Plate Overview and Crafting Purpose
Bone Plate is a bony growth that once covered a fish. It serves as a valuable resource for boat upgrades. Unlike common salvage components, Bone Plate cannot be recovered from floating cargo or salvage containers.
In your vessel storage, Bone Plate stacks up to a maximum stack of 50 units. Both the base price and default sell value to traders stand at 2 coins. Boat modules are crafted at the Ship upgrades table in the Dry Dock. Bait and upgrades for weapons, fishing gear, and tools are crafted at the Craft table in the Dry Dock.
Processing Predator Fish in the Grinder
Processing fish in the Grinder yields valuable ingredients. Drag a fish from your boat’s hold into the processor slot. Processing begins automatically and takes some time. Press and hold [F] to collect the processed resource.
Multiple species of fish yield Bone Plate when processed in the Grinder. A 
Gravedigger yields 2 Bone Plate, 3 
Chromatic Scales, 2 
Leeches, and 2 
Mutant Fish Meat. Some specimens of 
Shovelnose mutate into Gravediggers that inhabit flooded cemeteries.
Processing a 
Bully produces 3 Bone Plate, 2 
Jaws, and 3 
Fish Meat. The Bully is covered in folded skin rather than conventional scales. A 
Stonegnawer yields 3 Bone Plate, 2 Jaws, 3 Leeches, and 2 Mutant Fish Meat.
Feeding a Shovelnose into the machine produces 1 Bone Plate, 2 Chromatic Scales, and 2 Fish Meat. A 
Bonescar provides 2 Bone Plate, 2 Jaws, and 2 Fish Meat upon processing. Wounds on the body of a Bonescar heal over with ossified flesh. Processing a 
Rammfish produces 2 Bone Plate, 2 Mutant Fish Meat, 1 Jaws, 3 Leeches, and 1 
Bony Horn.
