Tuna

Tuna is a food item made by cooking raw tuna. It is fairly popular among free players, as it heals 100 Life Points a piece. Since the Karamja fishing spot is not very far from a lesser demon area where people train, it can be a useful food. However in Karamja, many players drop tuna while fishing for swordfish. This is helpful so that players could get free fish to trade or fish for lesser demons in the near by volcano.

Members can use it in baked potatoes with sweetcorn to make tuna and corn, which heals a bit more than regular tunas. The cost of tuna can be made to profit this way. It requires 30 cooking to cook, yielding 100 experience. Potato with butter can also be added with tuna-and-sweetcorn to create a tuna potato, yielding another 10 experience and a 220-LP-healing food.

They are probably one of the best ways to achieve 99 cooking on free worlds as they are quite easy to get from players who are fishing swordfish, and provide decent experience. Factoring in the time/cost ratio, it is probably the most cost-effective and fast way to achieve 99 cooking in free-to-play. At times, it is widely used in members worlds, especially during summer holidays, the peak of new players enter in the entire year. This is due to the whole lot of less wealthy members coming.

Tuna is still a powerful and cheap healing tool though. Players will rarely burn tuna beginning at level 60 and will stop burning tuna at level 63 cooking (63 on range, 64 on fire). A more accurate test done on level 60-64 cooking has proven that the average rate of burning tuna (3 tests done, please add on) is 5 in every 5 inventories. Lucky members will notice that nothing is burnt. The most unlucky that one should get in this level range should be 3 burnt according to tests. It should be noted that the average is not very accurate when you have higher levels. Currently, if you have 61 cooking, the above tests' results are more accurate. From level 35-99, it takes 130,121 cooked tuna (13,012,025 experience), which would cost around 12,361,495 gp or 12.5 mil *. By cooking Tuna you will receive around 100k xp/hour as you can only cook around 1k per hour.

Trivia

 * When the Fishing skill was first released, tuna gave no fishing experience. This was fixed the next day.
 * Tuna is considered to be better than buying a swordfish because tuna are less expensive, costing only 1/5 of its price and healing only 40 LP less.
 * A burnt tuna is called "Burnt fish" along with all other F2P fish except Swordfishes, Lobsters and Shrimp.
