With a Cooking level of 72, the fish can be dissected with a knife to extract Zulrah's scales. Dissecting the fish can give 3-8 scales and 109-124 cooking experience. A player's Cooking level has an effect on how many scales are received when they are dissected. If your cooking level is in the mid 80s, you can expect to average around 5 scales per fish. With 90 Fishing and Cooking, you can expect to gain about 21,300 Fishing experience, 23,800 Cooking experience, and about 1,200 Zulrah scales per hour.
