What is fish barrel osrs?

Fish barrels are used in Old School RuneScape to store raw fish caught with the Fishing skill. They can be purchased from various fishing shops or made with the Construction skill at level 42. Fish can be stored in the barrel by using them on it, and then later retrieved by taking them out of the barrel. Fish barrels can store up to 30 of each type of raw fish, and are commonly used by players to save space in their inventory while fishing. They can also be traded on the Grand Exchange.
