Assessment for Atlantic Nova Scotia Snow Crab
Maritimes Science Advisory Process
1-2 March 2011
Dartmouth, Nova Scotia
Chairperson: Tara McIntyre
The snow crab fishery on the Atlantic Scotian Shelf occurs annually throughout the year, dependent upon the Crab Fishing Area (CFA). In support of the fishery, DFO Maritimes Fisheries & Aquaculture Management Branch requests Science Branch 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 2011 fishery.
- Assess the status of Atlantic Nova Scotia’s CFAs snow crab up to the end of 2010, using the following indicators:
- Snow crab survey biomass index of males greater than 95 cm (commercial sizes)
- Snow crab survey R-1 relative abundance
- Exploitation Rate
- Incidence of CC5 crab in the survey
- Relative exploitation rate from the survey
- Report on
- Commercial catch rates in the 2010 fishery, compared to those in previous years
- Abundance of female crab from the survey
- Evaluate the consequences of different harvest levels during the 2011 fishery on stock abundance and exploitation rate.
- Estimate by-catch of soft shell snow crab and non-snow crab species in the 2010 fisheries, as well as possible benthic impacts.
- Describe any relevant predator/prey interactions.
