Priority order:

  • Discards (decision has been made, question is what model to change)
  • New maturity
  • Expanded vs unexpanded comps (justification for change, what is the best practices)
  • Q- try autoregressive, density-dependent, no extra SE (switch float to estimate)
  • Ian email Rick about F method
  • Zero-centered rec devs
  • Take out commercial length data (fleet negative or lambda zero)
  • Profile over M and R0, look at index fits
  • Try no M prior (and then don't worry about max age)
  • Try 3 sex-specific parameters instead of 2 (commercial)
  • Try sex-specific recreational selectivity
  • Try age-based instead of length-based selectivity
  • Try age-based selectivity AND remove length data to explore impacts
  • Update ageing error
  • Update M prior
  • Recent block for hake fleet (to better characterize recent removals, selectivity is based on years in 90s and 00s with more catch and more comp data)

Indices

  • ORBS (ready) / OSP
  • H&L survey
  • oceanographic index (ready)
  • SMURF (ready)
  • Observer data (just need to save output)
