Spawning Stock Biomass — 20-Year Trend
Shaded band shows 95% confidence interval. Dashed lines show Bmsy (green) and 0.5 × Bmsy (red) reference points.
What-If: Fishing Mortality Adjustment
Illustrative only. This slider applies a simple Schaefer surplus-production model
to show possible trajectories. Official catch limits are set by NOAA scientists using
full stock assessment models and peer review.
How to read this:
- Negative = reduced fishing pressure
- Positive = increased fishing pressure
- Shaded cone shows uncertainty; wider cone = more years ahead
