Description:The addition of the new method for estimating the fishery catch-at-lengths and applying ADF&G port sampling data in the pot fishery made only a small difference in model results and was an improvement of how estimates were derived. Model 17.09.35 provided the best fit to the data represents a balance between acknowledging a mortality event (with M changing in 2015-2016) and overfitting survey data. Also, this model performed well in retrospective analyses. This recommended model configuration differs from the 2016 Model in allowing natural mortality to change for 2015 and 2016. It also adds a feature that allows the catchability in the AFSC longline RPN index to be conditioned on water temperature.
