Plaice is a long-lived species and subject to high fishing pressure. Stock biomass has increased and is currently around the highest level recorded. Trawl fisheries are associated with high levels of discarding. Of a total catch of 7764 tonnes of plaice in the Eastern Channel in 2017, 52% comprised unwanted catch. 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.

The spawning-stock biomass (SSB) has increased rapidly from 2010 following a period of high recruitment between 2009 and 2015, and is now well above the MSY Btrigger. Fishing mortality (F) has declined since the early 2000s and it has been below FMSY since 2009. Recruitment (R) is currently around the average of the time-series.
ICES assesses that fishing pressure on the stock is below FMSY, Fpa, and Flim; spawning-stock size is above MSY Btrigger, Bpa, and Blim.

No specific management objectives are known to ICES. The EU has proposed a multiannual management plan for the Western Waters, which is not yet finalised.
Management decisions are informed by an annual stock assessment, catches of plaice have closely followed the agreed Total Allowable Catches (TAC) over the last 5 years, and a comprehensive regulatory framework has been put in place.
A single TAC however covers both divisions 7.d and 7.e. Scientists advise that management should ensure that fishing opportunities are in line with the stock status for each of the stocks in the combined management area to ensure that both stocks are exploited sustainably. For this reason, scientists advise that separate management areas would be desirable.
Plaice is caught in a mixed fishery targeting sole, with 80 mm mesh size. This leads to many plaice being discarded because this mesh size is not matched to the minimum conservation reference size (MCRS).

Plaice in this area is mainly caught in 80 mm beam-trawl fisheries for sole and in mixed demersal fisheries using otter trawls. Trammel nets are also used. Bottom trawling can cause damage to the seabed in sensitive areas. Trawl fisheries for plaice have bycatch of both commercial and non-commercial species and high levels of discarding associated with them, particularly for flatfish. The mesh size regulation (80 mm) leads to a large number of plaice being discarded because this mesh size is not matched to the minimum conservation reference size (MRCS) of 27cm for plaice in EU waters. Of a total catch of 7764 tonnes of plaice in the Eastern Channel in 2017, 52% comprised unwanted catch. The approximate size at which 50% of females mature or first spawn is around 30-34cm.
