Data
[x] Update to 2023 for indices and catch
[x] Standardized length comps and length bin width
[x] Separate trawl into separate fleets for landings and removals. Comp data suggest small animals are discarded and the largest ones retained.
Modeling
[x] Look at dogfish SRR
[x] Develop priors
[x] Evaluate fit to indices
[ ] Forecast file - calculate reference points. Project current fixed TAC over short term and 2 generations
[x] Profile steepness, R0, index q
[x] Develop models for various hypotheses about index decline:
Lagged effect of F (low steepness?)
Index q due to movement offshore and/or survey timing
Additional M from predation, potentially as a stepwise increase. Sea lion population time series will be useful

We will likely use openMSE for projections
