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

Effects of the fishery on the ecosystem

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 B_lim (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.
