COMMON NAMES

Pouting, Bib

No information on the genetic structure of pouting in the north-east Atlantic could be found. Map denotes species distribution in the FAO 27 area (NE Atlantic).


ANALYSIS

Strengths

This species is considered resilient to over-fishing (Catchpole, 2011).

Weaknesses

 No quantitative assessment. Stock status is unknown. No specific management objectives for the stock. No systematic information on the extent of discards or the impact on the bottom habitats.

Options

Collect more biological information in order to allow a quantitative assessment of the stock. Develop specific management strategies. Conduct more research on the fishery impacts on the ecosystem.

Fisheries

Within FishSource, the term "fishery" is used to indicate each unique combination of a flag country with a fishing gear, operating within a particular management unit, upon a resource. That resource may have a known biological stock structure and/or may be assessed at another level for practical or jurisdictional reasons. A fishery is the finest scale of resolution captured in FishSource profiles, as it is generally the scale at which sustainability can most fairly and practically be evaluated.

Analysis

OVERVIEW

Strengths

This species is considered resilient to over-fishing (Catchpole, 2011).

Weaknesses

 No quantitative assessment. Stock status is unknown. No specific management objectives for the stock. No systematic information on the extent of discards or the impact on the bottom habitats.

Options

Collect more biological information in order to allow a quantitative assessment of the stock. Develop specific management strategies. Conduct more research on the fishery impacts on the ecosystem.

1.STOCK STATUS

STOCK ASSESSMENT

No stock assessment is conducted for this species. In the UK it was recently included in the “under-utilized species” and qualitatively assessed in terms of its resilience for overfishing. The system used, “Relative Life History Sensitivity Analysis”, uses biological information (e.g. growth, breeding strategies) to evaluate how sensitive the stock is to fishing pressure.

SCIENTIFIC ADVICE

CEFAS conducted an assessment on species that were often discarded due to their low commercial value. Selected species were then subject to a qualitative evaluation in terms of their resilience to fishing. The classification system, “Relative Life History Sensitivity Analysis”, uses biological data such as growth and breeding strategies to evaluate how fishing pressure can affect each species. Pouting was among the species considered resilient to over-fishing (Catchpole, 2011). No specific recommendations other that encouraging consumers to choose this species were made.

Reference Points

There are no reference points defined.

CURRENT STATUS

Stock status is unknown. According to CEFAS “Relative Life History Sensitivity Analysis”, the species was included among the most tolerant to over-fishing (Catchpole, 2011).

Trends

Official landings by the UK have fluctuated between 400 and 1,000 tonnes (ICES, 2012). After a low in 2007, landings of pouting have been increasing ever since. Biomass or exploitation rates are unknown, but trawl surveys conducted in the English Channel indicate that the stock is “stable with a decrease in abundance since 2005” (Catchpole, 2011).

2.MANAGEMENT QUALITY

MANAGEMENT

Pouting is taken as by-catch of other whitefish fisheries. No TACs or other specific management measures (e.g. minimum size limits) are in place for this species. Trawlers that take pouting as bycatch are however subject to gear restrictions such as minimum mesh sizes.

Recovery Plans

Not applicable.

COMPLIANCE

No TACs or quotas or other specific management measures (e.g. minimum landing sizes) are in place, thus compliance cannot be evaluated.

3.ENVIRONMENT AND BIODIVERSITY

BYCATCH
ETP Species

Cetacean bycatch in demersal trawling in the UK is generally rare and not thought to pose a risk (Defra, 2003). Interactions of the fishery with skates and rays are considered to be high in some areas (ICES, 2008).

Other Species

Pouting is taken as bycatch of other whitefish fisheries. Results from on-board observers indicate that discard rates in the otter trawl fishery in ICES sub Area VII can be around 60%, but sampling coverage is insufficient for more robust estimates (Catchpole, 2008). Some projects are underway to increase selectivity in the UK fisheries and reduce discards (CEFAS, 2011).

HABITAT

Impact on the seabed habitat and some changes in the benthic community structure are expected in the beam trawl fisheries. However, there is not enough available information to evaluate the impact of this fishery in particular.

Marine Reserves

A comprehensive network of Marine Protected Areas has been designated in the UK (JNCC, 2012).

The score is < 6.

No specific management strategy. Although this species is considered resilient to fishing pressure, the stock status is currently unknown as no stock assessment is conducted.

DATA NOTES

*Notes: 1)* The stock status is unknown. No stock assessment is conducted, and no reference points have been defined for this stock. Additionally, no TACs or specific management measures (e.g. minimum size limits) are known to be in place, thus scores #2 and #3 cannot be calculated. Landings are from UK only (inc. Channel Islands) and for ICES Divisions VIId-f (ICES, 2012).
