Past season fish count information

Viewing Historical Data from Season

You are viewing completed-season fish count data for . Use the year control to pick any of the last 10 seasons, or open LIVE for the current season.

Historical Data Value

  • Compare current season performance with past years
  • Analyze long-term trends and patterns
  • Understand escapement goal performance over time
  • Review seasonal run timing and peak periods

Data Source

Historical data is maintained in ADF&G archives and provides a comparison baseline for current season analysis. All data is sourced from official Alaska Department of Fish and Game monitoring programs.

Goal Types Explained

Definitions follow ADF&G’s escapement-goal explanation. In-season station totals are preliminary passage relative to the goal—not a final determination that a goal was “met.”

Escapement level known to provide sustained yield when a BEG cannot be estimated

A Sustainable Escapement Goal (SEG) is a level of escapement—indicated by an index or escapement estimate—that is known to provide for sustained yield over a 5- to 10-year period. ADF&G uses an SEG when a Biological Escapement Goal cannot be estimated (for example, when a stock-specific catch estimate is unavailable).

The SEG is the primary management objective for escapement unless the Board of Fisheries has adopted an Optimal Escapement Goal or inriver run goal. It is developed from the best available biological information and stated as a range that accounts for data uncertainty. It is not necessarily an “optimal” range derived from spawner–recruit analysis.

ADF&G escapement goals

Scientifically defensible escapement range with greatest potential for maximum sustained yield

A Biological Escapement Goal (BEG) is the escapement that provides the greatest potential for maximum sustained yield. It is not an “absolute minimum” or a safety threshold below which a stock collapses.

A BEG is the primary management objective for escapement unless an Optimal Escapement Goal or inriver run goal has been adopted. It is developed from the best biological information, should be scientifically defensible, and is expressed as a range that reflects stock productivity and data uncertainty.

ADF&G escapement goals

Board-set passage objective: escapement goal plus upstream fishery allocations

An Inriver Goal (also called an inriver run goal) is a Board of Fisheries management objective for stocks harvested upstream of where escapement is estimated. It is comprised of the SEG, BEG, or OEG plus specific allocations to inriver fisheries.

It is not primarily an ecosystem-health target. ADF&G must leave enough returning salmon unharvested to meet the underlying escapement goal and to make a certain number of salmon available for upstream harvests.

ADF&G escapement goals

Board-adopted objective incorporating biological and allocative considerations

An Optimal Escapement Goal (OEG) is a specific Board of Fisheries management objective for salmon escapement that considers biological and allocative factors and may differ from the SEG or BEG.

An OEG will be sustainable and may be expressed as a range. The department seeks to maintain evenly distributed escapements within the bounds of the OEG. OEGs can add fish to a BEG or SEG for inriver fisheries or for escapement when there is uncertainty in the data used to set the underlying goal.

Current Season Status

Counts below are preliminary passage relative to goal minima—not final goal attainment. Some goals exclude hatchery fish, jacks, or smaller fish; some require subtracting upstream harvest; some sonar totals include multiple species.
