Science Advisory Process on Assessment for Eastern Nova Scotia Snow Crab

7 – 8 March 2007
Mic Mac Amateur Aquatic Club, 192 Prince Albert Road, Dartmouth, Nova Scotia

Context

The snow crab fishery on the Eastern Scotian Shelf occurs annually during June to November, dependent upon the Crab Fishing Area (CFA). In support of the fishery, DFO Maritimes Fisheries Management requests Science for an assessment of resource status and the consequences of various harvest levels for the coming fishing season. The current meeting is a scientific review of the assessment and projections undertaken in support of the 2007 fishery.

Objectives

• Assess the status of Eastern Nova Scotia’s CFA's snow crab up to the end of 2006, using the following indicators: ƒ
  • Abundance
    • Snow crab survey biomass index of males greater than 95 cm (commercial sizes)
  • Recruitment
    • Snow crab survey R-1 relative abundance ƒ
  • Exploitation Rate
    • Incidence of CC5 crab in the survey
    • Relative exploitation rate from the survey
  • Report on:
    • Commercial catch rates in the 2006 fishery, compared to those in previous years
    • Abundance of female crab from the survey
• Evaluate the consequences of different harvest levels during the 2007 fishery on stock abundance and exploitation rate
• Estimate by-catch of non-snow crab species from the past three fishing seasons
