Cooked Fish Meat is a common source of food in Ark Survival Evolved. It is also used in some of the Rockwell Recipes and does not spoil as quickly as Cooked Meat.
Cooked Fish Meat is produced by cooking Raw Fish Meat in either the Campfire or the Industrial Grill. It can be stored in the Preserving Bin or the Refrigerator to extend the amount of time you have before it spoils. This meat does not give you as much food value when eaten.
The fastest way to cook Raw Fish Meat to produce Cooked Fish Meat is by using the Industrial Grill. Fishing is the fastest way to get larger quantities of Raw Fish Meat.
