Burnt fish is the result of accidentally burning a raw sardine while attempting to make a sardine. Cooking sardines requires 1 Cooking, and burning it will become less common with a higher Cooking level. They stop being burned at 34 Cooking.
The burnt fish has no use whatsoever. Like most other burnt food, it is tradeable to other players but not on the Grand Exchange.
