Estimating Alaska Halibut Weights

Not all anglers have the luxury of weighing their halibut catch on a scale. This table may be used to estimate the approximate NET weight of a halibut from its length. The table shows the length measured from the tip of snout to the end of the center of the tail. The average net weight (head and viscera removed) and the Live weight estimate are to the right of the length.

The halibut of Resurrection Bay, Prince William Sound, Kachemak Bay and Cook Inlet have a tremendous range of size. The typical halibut caught in these waters by sportfishermen on charters and private boats average about 30 pounds with any day's catch including fish from 15 lbs. to over 100 lbs. Each year fish are brought in exceeding 300 lbs. in these waters with an occasional 400 pounder.
