2022 Assessment

SRG Request # 10

The SRG notes that there are currently multiple strong cohorts in the stock where previously there was only one strong cohort during the period of sample collection for the ageing error matrix that supports the assessment model. Based on this observation, the SRG recommends that an ageing error study using samples collected during the past decade be conducted in conjunction with the Committee of Age Reading Experts (CARE).

In short, this study has been initiated but has been held up due to the inability to send age structures to Canada. The proper permits need to be filled out and filed. So for now, just responding with:

An ageing error study in conjunction with CARE has commenced, including planned sample exchanges between United States and Canada ageing labs. However, a full exchange is on hold until there are staff to process the necessary aquatic animal health import permits to send age structures to Canada.

This was also a 2023 SRG Request.

  1. The SRG notes that there have been multiple strong cohorts in the stock recently compared to earlier periods where there was only one strong cohort supporting the stock, including during the period of sample collection for the ageing error matrix that supports the assessment model. Therefore, the SRG encourages the resumption of the ageing error study by the Committee of Age Reading Experts (CARE) using samples collected during the past decade. The exchange is still limited by lack of permits.
