Age and Growth Fish Otolith Thin Sectioning Procedures

Thin sectioning is used to supplement the break and burn method in the age determination of rockfish species and other difficult to age species. The AFSC thin section method is a modified version of a similar thin section technique developed in Australia. The modified thin section was used to develop the ageing criteria for shortraker rockfish and Pacific cod and is currently the primary method used to age shortraker rockfish. Below is a brief description of the procedure along with accompanying photographs.

North Pacific Observer Duties

Fisheries observers are biologists who work independently to collect a wide range of information onboard commercial fishing vessels and at shoreside processing plants receiving fish from Alaskan waters. Observer information is used by NOAA Fisheries and partner agencies to manage commercial fisheries in the North Pacific. Observers are deployed by permitted providers for up to three months at a time.
