Accounting for sampling and subsampling routines for aged fish

[kellijohnson-NOAA]

For the document, it would be good to know which age samples were subsampled for reads. For example, I have an email from @aliwhitman on 2020-08-14 "Oregon lingcod fin rays" that mentions both commercial and recreational age structures were subsampled to choose which fins to mount and read. This could affect marginal versus conditional ages. Please reply to this issue with any information you have.

• [ ] Find information for the following:
  • Commercial
    • [ ] WA
    • [ ] OR
    • [ ] CA
  • Recreational
    • [ ] WA
    • [ ] OR
    • [ ] CA
• [ ] Determine if any sensitivity runs need to be conducted to explore marginal vs. CAAL b/c of how data were sampled or subsampled
• [ ] Add information to the document

I have some information on the OR samples.

Commercial

• no subsampling occurred for the new 2017 - 2019 ages, all samples were aged, with the exception of a few samples that were poorly mounted, so census! [ ] past years, I'm going to need to dig some more - it looks like there are more samples than were aged at a glance at PacFIN

Recreational

• this year, there are new ages from 2013 and 2017 - 2019
• These were subsampled to 260 fins/year in proportion to the monthly proportion of annual landings
• for years 2012 and 2014 - 2016 (the "new" ages for the last assessment), we were instructed to subsample to 260 fins per year but in a stratified random procedure
• 130 fins per male/female, and then age more heavily at the tails of the length distributions
• there were very specific procedures for the distribution of the subsampling for the last assessment that I have outlined in an email and I can provide that if need be [ ] other years (<2012), I'm going to need to dig some more

not sure why my check boxes aren't showing up :(
