Sustainability overview

The state of the stock in this area is unknown but indications are it may be in decline. Avoid eating immature plaice below 30cm and during their breeding season, January to March.


Plaice is a bottom-dwelling flatfish. It spawns in the early months of the year (January to March) and sometimes makes long spawning migrations. North Sea plaice reach between 35 and 45 cm in their 6th year. It is a long-lived species, becoming sexually mature at 3-7 years (females) 2-6 (males) and living 30 years or more. Maximum reported age 50 years.

West of Ireland

Stock information

There is no information on abundance or exploitation for this stock. Stock status is unknown. Only landings statistics are available which is insufficient information to evaluate the stock. Catches in the area are too low to support the collection of data to assess stock status. Landings since 2000 have been low. ICES advises that when the precautionary approach is applied, landings should be no more than 24 tonnes in each of the years 2018, 2019 and 2020. ICES cannot quantify the corresponding total catches. Discards are also unknown.


Criterion score: 1 info

No specific management objectives are known to ICES. There is no management plan for plaice in this area. There is an agreed Total Allowable Catch (TAC).

Capture Information

Criterion score: 0.25 info

There is a potential for damage to the seabed by trawling. Trawling is also associated with discarding of unwanted fish i.e. undersized and/or non-quota and/or over-quota species. Discarding is known to take place but cannot be quantified. The minimum landing size for plaice in EU waters is 27cm. The approximate size at which 50% of females mature or first spawn is around 30-34cm.
