Terms of Reference for the EBS pollock CIE review

1.     Evaluation, findings, and recommendations on quality of input data and methods used to process them for inclusion in the assessment.  In particular:

a.     Is the use of the index of acoustic backscatter from opportunistic (AVO) used appropriately?

b.     Is modeling observed numbers from surveys appropriate?

c.     How should data on mean body mass at age be best used for model projections?

d.     How should the various data sets be weighted?

2.     Evaluate and provide recommendations on model structure, assumptions, and estimation procedures uses to assess stock status and condition.  In particular:

a.     Are the selectivity approaches used for surveys and fishery appropriate?

b.     How should trans-boundary aspects of the resource be handled?

c.     What constraints, if any, should be placed on survey catchability?

d.     How should model projection alternatives be evaluated/presented?

e.     Anything else on which the reviewers care to comment.

3.     Evaluate and provide recommendations on harvest recommendations provided by the NPFMC Tier system in the context of the 2,000,000 t BSAI cap and realized management recommendations

4.     Evaluate the extent that ecosystem data are presently included in the assessment and recommend how and where improvements can be made.
