Age data for 2021 NBS Vesteraalen pollock have been added to RACEBASE

[NancyRoberson]

Hi Mod Squad,

FYI, age data have been added to RACEBASE for 2021 NBS Vesteraalen pollock. n= 192. It is the full set and not a subset of the specimens collected.

Thanks!
Nancy

Thanks Nancy! Jim - New age data just came in for pollock. These were not incorporated into the hindcast ALK. I just wanted to verify what you want for the production runs this fall...I'm assuming we want to incorporate all complete years in the ALK (or is there another consideration for how you want to incorporate new NBS data specifically?)? Do you also want another run with the old ALK and new lengths to bridge? Lewis

Ideally it would be great to see the 2021 data updated and run to compare with how much it changes the 2021 values I presently use. Historically, Stan would make a couple of different design-based versions (i.e., with 2 ALKs vs 1 ALK). It'd be interesting to have runs for the historical data done this way and perhaps adding in a third version w/ 3 ALKs (the third being NBS all on its own). That seems like step one (but if the 3-ALK version is too complicated it's probably ok to omit). Then we'd need to decide how to fold in the new NBS data into the VAST modeled age-composition estimates (I guess that should be straightforward since it's just adding in more data that's spatially resolved). It would also be cool to compare how they would come out. As far as production runs in the fall, I'm unsure the age-growth group can handle getting more samples done in the current year (they've already requested reductions from past requests). So the additions may have to occur as resources become available within their group. The results from the outline above could help guide prioritizations in this regard. Cheers! Jim

Gotcha Jim, thanks for weighing in. We can start with examining the differences in the age-length key itself (and the design-based comps). As you noted, it will be straightforward to include the new ALK in the VAST comps, but certainly more time-consuming to complete all iterations, so we'll check to see how much the ALK changes first.

Hi All, I have heard the data will be finalized within the next few days to a week. This is a reminder to plan to start running production indices/comps as soon as possible after the data are in. As another reminder, those running models of age composition should determine whether there are updated ages that have been processed that should be incorporated into the ALK (based on issues posted by Nancy Roberson: #46). If there are new data going into an ALK, be sure to compare the resulting new ALK to the prior ALK to ensure that any differences are relatively minor. For the Bering data, once we get the word that the data are finalized, we need to make some tables accessible to sumfish by running this function: sumfish::updateSurvey() ...or otherwise obtain the precursor data from gapindex (but I think not quite everything is ready there? Zack let us know if we can make the transition this production cycle or to hold off). I may be out when the data are finalized, so in that case I would appreciate it if somebody else with sumfish installed could run that and let folks know it is complete before running the NBS data prep code in the model-based-index repo. If you have any questions or just want to look through outputs together, please let me know and/or find a time on my calendar. Thanks! Lewis
