Exploitation
 

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 2017.

Recent catches and agreed effort were as follows:
  2008 2009 2010 2011 2012 2013 2014 2015 2016 2017

Assessment
 
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).
Projection

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

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

This stock is now assessed biennialy. The next full assessment is currently scheduled for 2018.

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 coincided 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 and redfish 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.

Management Advice

Recommendation for 2018 and 2019

No directed fishery for 2018 and 2019 as the stock is below Blim.
Management Objectives

Stock definition for management purposes

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