Following several years of low recruitment, the spawning stock has declined, and has remained below Blim since 2011. Due to continued poor recruitment there are concerns that the stock will remain at low levels.

This fishery is effort-regulated. The effort allocations were reduced by 50% in 2010 and a moratorium was imposed in 2011. Catches are expected to be close to zero in 2013.

Recent catches were as follows:

Effects of the fishery on the ecosystem

No fishery.
Overall Assessment Results
Reference Point

Scientific Council considers that a female survey biomass index of 15% of its maximum observed level (2564) provides a proxy for Blim (SCS Doc. 04/12).

Quantitative assessment of risk at various catch options is not possible for this stock at this time.
Assessment Model
Analytical assessment

No analytical assessment is available. Evaluation of stock status is based upon fishery and research survey data.

This stock is typically assessed annually. The next full assessment is currently scheduled for 2015. Scientific Council suggests this stock be moved to biennial assessments.

Human impact

Low fishery related mortality due to moratorium and low bycatch in other fisheries. Other sources (e.g. pollution, shipping, oil-industry) are considered minor.

Biological and environmental interactions

The drastic decline of shrimp biomass since 2007 correlates with the increase of the cod stock in Div. 3M. It is uncertain whether this represents a causal relationship and/or the result of an environmental factor.

Results of modelling suggest that, in unexploited conditions, cod would be expected to be a highly dominant component of the system, and high shrimp stock sizes, like the ones observed in the 1998 – 2007 period, would not be a stable feature in the Flemish Cap.

Special comments

Management unit: Yes

Management Advice

Recommendation for 2015

No directed fishery.
Management Objectives

No explicit management plan or management objectives defined by Fisheries Commission. General convention objectives (GC Doc. 08-03) are applied. Advice is based on qualitative evaluation of biomass indices in relation to historic levels, and provided in the context of the precautionary approach framework (FC Doc. 04/18).

Stock definition for management purposes

The Northern Shrimp stock on Flemish Cap is considered to be a separate population.
