Considered a management unit: An aquatic resource or fishery is
declared as [Fishery] Management Unit if it is
effectively the focus for the application of selected
management methods and measures, within the broader
framework of a management system. According to the FAO
Glossary for Responsible Fishing, "a Fishery Management
Unit (FMU) is a fishery or a portion of a fishery
identified in a Fishery Management Plan (FMP) relevant
to the FMP's management objectives." FMU's may be
organised around fisheries biological, geographic,
economic, technical, social or ecological dimensions ,
and the makeup and attribute of a fishery management
unit depends mainly on the FMP's management
objectives. |
Jurisdictional distribution: Jurisdictional qualifier (e.g.
"shared", "shared - highly migratory") of the aquatic
resource related with its spatial distribution. |
Environmental group: Classification of the aquatic
resource according to the environmental group (e.g.
pelagic invertebrate, or demersal fish) to which the
species belong. |
Reference Year: The Reference Year is the last year considered in the stock assessment and/or fishery status. |
| | | | Aq Res State Trend The stock has increased in recent years due to improved recruitment (at age 3) since 2009, and recovered to the levels of the mid 1990s, when the fishery was closed. Both catches and F remain low, although slightly higher catches are observed since 2013. Habitat Bio Climatic Zone: Temperate. Bottom Type: Unspecified. Depth Zone: Slope - Deepslope (500 m - 1000 m). Horizontal Dist: Oceanic. Vertical Dist: Demersal/Benthic.

Water Area OverviewAmerican Plaice - Flemish Cap Aq Res Struct Biological Stock: Yes Exploit American plaice is caught as bycatch in otter trawl fisheries, mainly the cod and redfish fisheries. From 1979 to 1993 a TAC of 2 000 tonnes was in effect for this stock. A reduction to 1 000 tonnes was agreed for 1994 and 1995 and a moratorium was agreed to thereafter. Recent catch estimates and TACs (‘000 tonnes) are as follows: Effects of the fishery on the ecosystemNo directed fishery. General impacts of fishing gear on the ecosystem should be considered. Bio Assess Results Ref Point Scientific Council is not in a position to provide proxies for biomass or fishing mortality reference points at this time. Projection Quantitative assessment of risk at various catch options is not possible at this time. Assess Models Analytical assessment Results This assessment is based upon a qualitative evaluation of research vessel survey series and bycatch data from commercial fisheries. The next full assessment is planned for 2023. Fishing MortalityRecruitmentBiomassHuman impactMainly fishery related mortality. Other sources (e.g. pollution, shipping, oil-industry) are undocumented. Biological and environmental interactionsThe stock occurs mainly at depths shallower than 600 m on Flemish Cap. Main stomach contents are echinoderms, shrimp and hyperiids. Management Management unit: Yes Advice Recommendation for 2021 - 2023The stock has recovered to the levels of the mid 1990s, when the fishery was closed. SC considers that there is not sufficient evidence that the stock would be able to sustain a fishery at this time and recommends that there be no directed fishing in 2021, 2022 and 2023. Bycatch should be kept at the lowest possible level. Objectives No explicit management plan or management objectives defined by Fisheries Commission. General Convention objectives (GC Doc. 08/3) are applied. Stock definition for management purposesThe American plaice stock in Flemish Cap (Div. 3M) is considered to be a distinct population.
