Mark Recovery Laboratory
- Mark Summary Report
The Mark Recovery Lab at the ADF&G Mark, Tag and Age (MTA) Laboratory examines salmon otoliths from commercial fisheries, test fisheries, and escapement surveys for
artificially-induced marks and provides mark characteristic reports and to provide otolith mark recovery data to biologists for fishery management.
- Voucher Summary Report
The Voucher Summary Report provides characteristics and descriptions of marks applied to salmon otoliths by hatcheries.
We examine a representative sample of otoliths from each group of marked salmon as eggs, fry, or smolt.
The Mark Characteristic Report includes images of the otolith mark, measurements of the mark, and images representative of lots that do not show the proposed mark (variants ).
