Petrale STAR Day 1 Requests

1. plot random vessel-year effects versus year for NWFSC survey Presence-Absence Positive

2. Compare NWFSC indices and error bars when year-strata effects are random or fixed Model 1 – Strata:Year Fixed Model 2 – Strata:Year Random

3. Report what depth selection was used for fishery CPUE. • Depth selection was: Depth ≤ 75 fathoms (for Summer) 150 fathoms ≤ Depth ≤ 400 fathoms (for Winter)

4. Look at vonB residuals by year.

5. Set the NWFSC extra variance parameter to zero. • Base_old (Estimate extra SD for NWFSC) • Base (Extra SD for NWFSC=0)

6. Provide a time-series plot of discarded catch by fleet.

7. Check for convergence the sensitivity run removes NWFSC 2012 age composition data. • Run in draft document removed ALL NWFSC survey age data • New run removes only 2012 NWFSC survey age data

8. Report statistics on jitter analyses. • Jitter of 0.01 run for base case, 100 times • 75% ended at base case • 17.5% ended at local minima • 7.5% crashed

9. Provide M and h sensitivity analyses, based on range from hessian-based intervals.

9. Provide M and h sensitivity analyses, based on range from hessian-based intervals. • low h = 0.78; high h= 0.91

9. Provide M and h sensitivity analyses, based on range from hessian-based intervals. • low M = 0.14; high M= 0.18

10. Provide a sensitivity run with no commercial CPUE

Comparison of all model runs for Day 1 STAR Requests

11. If time permits, provide an explanation of what component(s) produced the increase in the total likelihood profile for Ro.
