Tyee Test Fishery: Skeena River Index & 2025 Update

 

A short intro:
In summary, the Tyee Test Fishery is a long-established gill-net monitoring program situated at the Skeena River’s mouth. It plays a key role in estimating sockeye returns and tracking steelhead levels over time. This article explains methods, 2024 results, 2025 in-season updates and why managers and anglers rely on Tyee data.

INTRODUCTION

SEO SNIPPET: The Tyee Test Fishery has been a core, in-season monitoring tool for Skeena salmon and steelhead since the 1950s — critical for forecasts and management decisions.

The Tyee Test Fishery, located in the lower Skeena River, operates as a gill-net program that collects daily data on sockeye escapement, steelhead presence, and overall species mix. These records support Fisheries and Oceans Canada (DFO), provincial regulators, Indigenous organizations, and international stakeholders in managing both commercial and recreational fisheries. Launched in the mid-1950s, the initiative has grown into one of the Pacific coast’s longest-running monitoring projects. Today, it brings together Indigenous communities, local managers, and global partners to guide both recreational and commercial fishery management; its daily index is combined with commercial catch data and age/stock-composition samples to form in-season forecasts and run reconstructions. pac.dfo-mpo.gc.cadata.skeenasalmon.info

Why this matters (short summary): managers use Tyee indexes to set openings/closures and to estimate escapement; researchers use the long time-series to track trends in abundance, age structure and body size. Government of Canada Publications

TYEE TEST FISHERY

SEO SNIPPET: Definition, methods and the operational details of the Tyee gillnet test fishery, including net design, timing and sampling procedures.

Operating each year from early June until late August or September, the Tyee Test Fishery uses a drifting, commercial-style gill-net at Tyee Bar near the Skeena River estuary. The test set is standardized (net type, mesh panels, set timing tied to tide and discharge) so index values remain comparable across years. Catch is recorded daily and species, size and age samples are collected to inform in-season run size estimates and post-season analyses. The program’s standardization, combined with long time series, makes Tyee a powerful index for aggregate Skeena returns (sockeye, pinks, steelhead, occasional coho/chinook). pac.dfo-mpo.gc.cadata.skeenasalmon.info

SKEENA TYEE TEST FISHERY

SEO SNIPPET: Contextualizing Tyee within the Skeena watershed — what stocks it tracks and how the index is used in management.

The Tyee index is specifically tuned to the Skeena system: because Babine/Lake Babine sockeye often dominate the aggregate return, Tyee sampling coupled with age/genetic sampling is used to apportion the aggregate run to component stocks. Tyee results feed into the Total Return to Canada (TRTC) for sockeye and provide the primary in-season index for Skeena steelhead. Test-fish samples also support genetic stock identification and age composition work important for run reconstructions. Government of Canada PublicationsPacific Salmon Commission

SKEENA TYEE TEST FISHERY REPORT

SEO SNIPPET: A standard Tyee report generally summarizes daily escapement values, includes biological sampling such as age and size, genetic analysis where available, and provides management notes.

Content normally found in a Tyee report includes daily indices by species, running totals, estimates of how much of the migration has already occurred, biological details such as size and age measurements, and in many years, DNA stock identification for sockeye to determine the share of returns by tributary (e.g., Babine). Reports and datasets may be published as daily in-season dashboards, PDF summaries, or datasets used in scientific publications and management reports. These reports are critical inputs for TRTC forecasts and for multinational management discussions (e.g., Northern Boundary technical committees).

SKEENA TYEE TEST FISHERY 2024 RESULTS

SEO SNIPPET: A closer look at the measurable outcomes from 2024 — species counts, escapement patterns and management implications.

Steelhead: 2024’s Tyee counts showed strong steelhead escapement relative to recent low years — government summaries and third-party analyses put mid-late season counts in the tens of thousands (estimates reported in mid-August). The strong year reduced immediate conservation concerns but did not eliminate long-term vulnerabilities for specific stocks. Government of British ColumbiaWild Salmon Center

Sockeye and others: 2024 sockeye in-season totals and forecasts were monitored closely as Tyee daily escapement accumulated; datasets and DFO updates were used to judge fisheries openings for Area 4/29 and in boundary area planning. The details of escapement timing and age composition were essential for apportioning returns to Babine and other sub-stocks. Government of Canada Publicationswww-ops2.pac.dfo-mpo.gc.ca

EXPANDED FAQ

Q1 — What is the Tyee Test Fishery and why is it important?
A: The Tyee Test Fishery is a structured gillnet program located at the Skeena River mouth, designed to generate daily estimates of sockeye escapement and track relative abundance of steelhead along with other salmon species. It is important because its long, consistent record underpins in-season forecasts and management decisions by DFO and partners. pac.dfo-mpo.gc.ca

Q2 — How does the Tyee Test Fishery estimate sockeye run size?
A: Daily catches are recorded, age/length/genetic samples are taken, and those indices are combined with commercial catch estimates to produce a Total Return to Canada (TRTC) estimate for sockeye. These are provisional in-season and refined post-season with run reconstructions. Pacific Salmon CommissionGovernment of Canada Publications

Q3 — Where can I find daily Tyee counts and historical data?
A: DFO’s Pacific Region pages and the Skeena Salmon data portal publish daily index summaries and historic datasets for public download and visualization. pac.dfo-mpo.gc.cadata.skeenasalmon.info

Q4 — Were Tyee counts reliable in 2024 and 2025?
A: Tyee counts are reliable as an index, but in-season estimators and multipliers can be revised (notably in 2025 there were reported corrections). The counts themselves are raw daily indices; the derived TRTC estimates rely on models and can be adjusted as data are checked. Always cite the latest official DFO notice when reporting. Facebookwww-ops2.pac.dfo-mpo.gc.ca

Q5 — How do Tyee results affect commercial openings?
A: Managers use Tyee’s daily escapement and TRTC forecasts to determine harvest opportunity and whether a surplus is available for directed commercial or boundary area fisheries; if Tyee indicates low escapement, openings can be reduced or closed. www-ops2.pac.dfo-mpo.gc.ca
