2019 STAR Panel: Region Growth

[chantelwetzel-noaa]

To understand whether regional differences in growth, and associated size or age composition, are behind the strong tensions observed in age and length composition data, future assessment models should evaluate having separate fixed gear fleets north and south of 36° N (as discussed in unresolved problems and major uncertainties). The potential merits of other regional differences in fleet structure could also be explored.

To Do:

• Explore area-based fleets.
• Explore regional growth north and south of 36° N
• Explore estimating weight-at-age
