3Ps Cod Stock Assessment

Newfoundland and Labrador Regional Peer Review Process

October 14-17, 2014
St. John's, NL

Chairperson: Darrell Mullowney

Context

The status of the Northwest Atlantic Fisheries Organization (NAFO) Subdivision 3Ps Cod was last assessed in October 2013 (DFO 2014). The main objectives were to evaluate the status of the stock and to provide scientific advice concerning conservation outcomes related to various fishery management options. The current assessment is requested by Fisheries and Aquaculture Management to provide the Minister with detailed advice on the status of the stock in order to inform the management decisions for the 2015 fishing season.

Objectives for the 3Ps Cod Assessment:

• Provide an ecosystem overview (e.g., environment, predators, prey) for the stock area.
• Assess and report on the current status of the 3Ps Cod stock. In particular, assess current spawning biomass relative to baseline conservation thresholds (Blim), total (age 3+) biomass, exploitation rate, natural mortality, total mortality, and biological characteristics (including age composition, size at age, age at maturity, and distribution). Describe these variables in relation to historic observations.
• Further to the previous assessment, analyze recent year class strength relative to previous observations, as it relates to long term growth and sustainability of the stock.
• To the extent possible with available information, provide information on the strengths of year-classes expected to enter the exploitable populations in the next 1-3 years.
• Provide annual projections to 2017 based on the assessment of trends in the abundance index, biomass index and other stock indicators, including associated risk analyses. Specifically, these analyses will include an assessment of the trends in the stock and in the risks compared to Blim.
• Highlight major sources of uncertainty in the assessment, and where appropriate, consider alternative analytical formulations of the assessment.
• Assess the implications on the stock of fishery removals ranging from 10,000t to 15,000t, at 2500t intervals.
• Report on results of tagging and the distribution of this stock in other areas (e.g., 3L/3Pn.)
• Provide an update on ongoing work to review the use and efficacy of spawning closures for the management of marine fish stocks.
• To the extent possible, review the performance of the Harvest Control Rule proposed for this stock.
