Definitions

Group A ages Bering Sea and Aleutian Island walleye pollock, rockfish, and forage fish.
Group B ages flatfish, Gulf of Alaska walleye pollock, Pacific cod, Atka mackerel, sablefish, and sculpins.
Group C specializes in difficult species, including giant grenadier and shortraker rockfish.

The "number read" column is a count of ages entered into in the AGEDATA database that are given a single age. Ranged specimens or ones deemed unageable are not counted.

CA: Continuing assessment
FRP: Funded research project with new specimen aging request
NEA: New/enhanced assessment
SP: Special project (no previous request)
NA: Request type and request priority are unavailable because they were initialized before the prioritization system.
