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.

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 ecosystem

No directed fishery. General impacts of fishing gear on the ecosystem should be considered.Special comments

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 Mortality

Recruitment

Biomass

Human impact

Mainly fishery related mortality. Other sources (e.g. pollution, shipping, oil-industry) are undocumented.

Biological and environmental interactions

The 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 2020

There 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.

Stock definition for management purposes

The American plaice stock in Flemish Cap (Div. 3M) is considered to be a distinct population.
