Science Advisory Report 2013/077
Stock Assessment of NAFO Subdivision 3Ps Witch Flounder
Summary
- Information available to evaluate stock status consisted of commercial landings data (1974‑2013) and information from Canadian research vessel (RV) trawl surveys (1983‑2013).
- The average annual landings for the past ten years were 375 t, about 35% of the 1986‑1993 average of 1100 t and well below the 650 t Total Allowable Catch (TAC).
- Size compositions from the fishery have changed relatively little from 2007-2013.
- The mean RV biomass index over 2008-13 has been relatively stable at 15% below the time-series average.
- Pre-recruit (16-30 cm) abundance from the RV survey showed no trend from 1997-2013.
This Science Advisory Report is from the October 15-18, 2013 Regional Peer Review Process for Subdivision 3Ps Cod and Witch Flounder. Additional publications from this meeting will be posted on the Fisheries and Oceans Canada (DFO) Science Advisory Schedule as they become available.
