| Main Descriptors | Considered a single stock: Yes
Spatial Scale: Regional
Management unit: Yes
Reference year: 2016
|
| Considered a single stock: A group of individuals in a species occupying a well defined spatial range independent of other stocks of the same species. It can be affected by random dispersal movements and directed migrations due to seasonal or reproductive activity. |
| Spatial Scale: Spatial scale contains a standard term such as Global, Regional (e.g. for the whole Atlantic), sub-regional (e.g. for a part of the Atlantic), national, local (for sub-national levels). |
| 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. |
| | | | | | Biological State and Trend The stock has increased slightly in recent years due to improved recruitment. Although the catches since 1996 have been low, this stock remains at a relatively low level. Habitat and Biology Climatic zone: Temperate. Bottom type: Unspecified. Depth zone: Slope - Deepslope (500 m - 1000 m). Horizontal distribution: Oceanic. Vertical distribution: Demersal/Benthic.

The following area codes have been found as intersecting the distribution of American Plaice - Flemish Cap Resource Structure Considered a single stock: Yes Exploitation 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 t was in effect for this stock. A reduction to 1 000 t was agreed for 1994 and 1995 and a moratorium was agreed to thereafter. Recent catch estimates and TACs are as follows:

Effects of the fishery on the ecosystemNo directed fishery. General impacts of fishing gear on the ecosystem should be considered.Special comments Special CommentsNo special comments Assessment Overall Assessment Results Reference Point Scientific Council is not in a position to provide proxies for biomass reference points at this time. Assessment Model 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 2020. 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 Management Advice Recommendation for 2018 to 2020There should be no directed fishery on American plaice in Div. 3M in 2018, 2019 and 2020. Bycatch should be kept at the lowest possible level. Management Objectives No explicit management plan or management objectives defined by Fisheries Commission. General Convention objectives (GC Doc. 08/3) are applied. The American plaice stock in Flemish Cap (Div. 3M) is considered to be a distinct population.
