Pacific Salmon and Steelhead High-seas Tag Recovery Program
High seas salmon tagging has been conducted from the 1950s to the present by placing disk tags on salmon and steelhead during research cruises in the North Pacific Ocean, Gulf of Alaska, and Bering Sea. These studies have been used to investigate ocean distribution, migration, and growth of salmon at sea. Reporting salmon and steelhead tag recoveries is important because it provides direct evidence of the distribution and ocean habitat of salmon, which can be affected by climatic changes, and helps to conserve salmon stocks in North Pacific ecosystems. Some disk-tagged fish also carry an electronic tag. Recoveries of undamaged electronic tags provide detailed information on the individual salmon’s behaviour by recording the fish’s swimming depth and other information about the fish’s habitat. Disk tags and electronic tags are easy to see because they are placed outside the fish’s body, near the dorsal fin. Please return high seas salmon and steelhead tags.
Rewards for Tag Recovery
Any member of the public (i.e. fishermen, processors, non fishery-agency personnel) who returns an NPAFC High Seas Tag will receive a custom-embroidered baseball cap with the high seas salmon tagging emblem. In addition, persons returning tags will be entered into the next drawing for cash prizes.
Several types of plastic disk tags have been placed on salmon and steelhead. These disk tags are about 3/4″ (19 mm) in diameter and each is imprinted with a unique identification number.
- red NPAFC-logo plastic disk tag (Fig. 1A and B)
- other tags are red and white, or solid red plastic disks (Fig. 1C and D).
Several types of electronic data-recording tags have been placed on salmon and steelhead.
- blue hexagonal tag (Fig. 2A; records water temperature)
- green rectangular tag (Fig. 2B; records water temperature and fish swimming depth)
- electronic cylindrical tag (Fig. 2C; records water temperature and fish swimming depth)
- white cylindrical tag (Fig. 2D; records water temperature, fish swimming depth, and salinity)
Guide for Reporting Tags
Tag return posters can be viewed for each member country:
What to do if You Catch a Tagged Fish
1) collect tag (if the tag cannot be collected, then record the tag number and description)
2) record catch location, date, time, species, sex, length, weight, and fishing gear
3) collect scales for age and growth information
4) send the tags and other information to one of addresses below. Make sure to include your name, address, and a phone number, so we can send you your tag recovery reward and provide you with information on when and where in the ocean your fish was tagged and released. Or call one of the contact numbers listed below.

Tag Recovery Data Request
REQUEST TO OBTAIN RECORDS FROM THE INPFC/NPAFC HIGH-SEAS SALMONID TAG-RECOVERY DATABASE
This database contains records on the high-seas release and recoveries of salmonids (1956–2011). High seas tags are external tags, mostly disk tags. This database does not contain high-seas recoveries of coded-wire tags (CWT).
If you are a user with access to the Members’ Area of this website, then go to that area for access to the database.
This is the procedure to use if you do not have access to the Members’ Area of this website:
1) Examine NPAFC Doc. 192 (1996) for a visual summary of the data. This document presents maps showing the high-seas locations of tagged salmon and steelhead grouped by area of coastal recovery. Although this document is dated, it shows the bulk of the data because most recoveries pre-date the mid-1990s. The document also cautions the user to possible biases in the data.
2) The format and codes used in the INPFC/NPAFC database are explained in NPAFC Doc. 1396. This document is needed to understand column descriptions and codes used in the database.
3) If you want to request tag-recovery records, please download the request form, fill it out, and email it to the Secretariat.
