Download agenda as PDF

Purpose: Examine multiple modeling approaches under consideration for use in the 2018 SAW/SARC stock assessment.

Meeting Objectives:

  1. Examine the current summer flounder assessment model in detail, as well as other sex-specific and spatially-explicit model frameworks that could be used for assessing the stock.
  2. Review supplemental analyses that may inform model choice and structure.
  3. Examine differences between the modeling approaches and potential biological reference point methods using older (y-1) data.
  4. Develop recommendations on next steps for modeling work, analyses, and preferred approaches that warrant further evaluation prior to the next SAW meeting.

Deadline for Working Papers: All working papers are due May 11, 2018. Please contact the SAW chair, Jessica Coakley (jcoakley@mafmc.org; 302-526-5252) if you intend to submit a working paper.

Meeting Logistics:

All meetings are being held in the Clark Conference room (aquarium building) Woods Hole, MA. Download directions to Woods Hole and the NEFSC laboratory.

You will not need to check in at the NEFSC front desk unless you are parking at NEFSC facilities. Upon arrival, we will provide participants with a code for the side door for times when the aquarium is not open.

Parking spaces may be limited at the NEFSC lab and attendees are encouraged to carpool if convenient. If you park in the NEFSC parking lots, you need to check in at the front desk for a parking pass and leave contact information if you block someone else in.

If you have questions about the meeting location or parking, contact the NEFSC front desk at 508-495-2000.
