Science Advisory Report 2018/031

An assessment of Iceland Scallop in the Canada-France Transboundary Zone of St. Pierre Bank

Summary

  • Directed fishing started in 1989 and peaked at 6,000 t in 1992. There has been no fishing from 1997 to 2016 with minimal fishing activity in the CORE area in 2017, where the Total Allowable Catch (TAC) is 1,650 t (total).
  • A Canadian research survey in September 2017 resulted in a minimum dredgeable biomass estimate of 1,200 t which is among the lowest in the survey time series, and a decrease of approximately 60% since 2009.
  • Mean shell height is consistently higher in Canadian waters than in French waters.
  • An average meat count of 85 scallop/500 g from the 2017 survey was the highest in the survey time series.
  • Predatory sea stars were observed at the lowest level in the survey time series in 2017.
  • The annual natural mortality estimate in 2017 was 7%, the lowest in the time series.

This Science Advisory Report is from the February 20, 2018 Assessment of Iceland Scallop on St. Pierre Bank. Additional publications from this meeting will be posted on the Fisheries and Oceans Canada (DFO) Science Advisory Schedule as they become available.
