Science Advisory Report 2018/018

An assessment of Northern Shrimp (Pandalus borealis)in Shrimp Fishing Areas 4-6 in 2017

Summary

  • Resource status of Northern Shrimp in SFAs 5 and 6 was assessed based on Fisheries and Oceans Canada (DFO) fall multi-species trawl survey data (1996–2017). Resource status for Northern Shrimp in SFA 4 was assessed based on Northern Shrimp Research Foundation (NSRF)-DFO summer trawl survey data (2005–17).
  • Trawl survey data for SFAs 4–6 provided information on shrimp distribution, length frequencies and biomass. Trends in fisheries performance were inferred from total allowable catch (TAC), commercial catch to date, fisher catch per unit effort (CPUE) and fishing patterns.
  • Research on larval dispersal within SFAs 4–6 indicated strong downstream connectivity and that a majority of recruits in a particular SFA may come from SFAs farther north.
  • Analysis was presented on the pre-1995 shrimp surveys, commercial and diet data in order to demonstrate historic changes in SFAs 5–6 indices. Results indicate that shrimp biomass has declined to a level consistent with their 1979-90 levels in SFA 6.

This Science Advisory Report is from the February 13-14, 2018 Assessment of Northern Shrimp in Shrimp Fishing Areas (SFAs) 4, 5 and 6. Additional publications from this meeting will be posted on the Fisheries and Oceans Canada (DFO) Science Advisory Schedule as they become available.
