Overview
Whiting is a slender bodied, sandy, blue-green coloured fish with conspicuous white sides and belly, silvery when alive. A member of the gadoid family, the same as cod and haddock, it occurs throughout northeast Atlantic waters at a wide range of depths, from shallow inshore waters to depths of 200m. They mature at an age of 2-3 years and at a length of about 30 cm. The average landed length is usually around 30-40 cm, however whiting can grow up to 70 cm and 3 kg. Whiting breeds between January and July, but mostly in spring. The maximum reported age is 20 years.

West of Scotland - Wild-caught
Location: All areas
Capture methods: Bottom trawl (otter)
The whiting population in the West of Scotland is below target levels, but is not subject to overfishing. Some appropriate management measures are in place for West of Scotland whiting. Historically, the stock has been subject to significant overfishing. Most whiting catches are by trawling, which is likely to cause some damage to the seabed. Bycatch is moderate and may include vulnerable species.Rating last updated August 2025.
North Sea, English Channel (East) - Wild-caught
Location: All areas
Capture methods: Bottom trawl (otter)
North Sea whiting is not overfished and not subject to overfishing. There are some but not all appropriate management measures in place. They are caught as part of a human consumption fishery and catch limits are the main management measure. From 2023 onward, human consumption catch does not have a separate quota. Most whiting catches are by otter trawls, which are likely to cause some damage to the seabed. Bycatch is moderate and may include vulnerable species such as blue and flapper skate, and cod.Rating last updated August 2024.
Rockall - Wild-caught
Location: All areas
Capture methods: Bottom trawl (otter)
There is very little information about Rockall whiting, and both biomass and fishing pressure appear to be of concern. There is no management plan and management requires considerable improvement. The main concern in this fishery is that landings consistently exceed advice. Most whiting in this area are bycatch by otter trawls. There are some vulnerable habitats and species in this area, which could be affected by the fishery.Rating last updated August 2024.
