Sustainability overview

Gurnards are non-quota species and are often discarded due to low market demand. Increased consumption and demand for the species will alleviate the need to waste fish through the practice of discarding. Grey gurnard appears to be the most resilient of the three gurnard species encountered in the north east Atlantic, and is taken as bycatch in trawl fisheries in deeper offshore waters. More research is needed to obtain a better understanding of the impact of fishing on the stock and provide information for its sustainable management, especially if the species is to become commercially targeted. Avoid eating immature fish (less than 24cm) and fresh (not previously frozen) fish caught during the spawning season (April-August).


Gurnards belong to a group of fish known collectively as Trigliadae (sea robins). Grey gurnard occurs in the eastern Atlantic from Iceland, Norway, southern Baltic, and North Sea to southern Morocco, and Madeira Islands. It is also found in the Mediterranean and Black Seas. In the North Sea and in Skagerrak/Kattegat, grey gurnard is an abundant demersal species. They have a strong seasonal migration throughout the North Sea. It forms dense semi-pelagic aggregations in winter to the northwest of the Dogger Bank; in summer, grey gurnard are more widespread. The species is less abundant in the English Channel, the Celtic Sea, and in the Bay of Biscay. Although an offshore species, grey gurnard is occasionally found in shallow water. They spawn from April to August in deep water. The maximum life span rarely exceeds 6 years. They can attain a length of 45 cm, but are usually around 30 cm. Sexually mature at a length of about 18 cms and an age of 3 years (males) and about 24 cms and 4 years (females).Gurnards are able to grunt or growl by the use of muscles associated with the swim bladder, and this is believed to aid in keeping schools together.

Stock information

This is a data-limited stock which means there is little information available on abundance and exploitation. Reference points are not defined and the status of the stock is unknown. Therefore, based on precautionary considerations, ICES advises that catches should not be allowed to increase in 2013. This advice is biennial and also valid for 2014, 2015 and 2016. Although there is no specific information available about the stock status of the grey gurnard, survey indices suggest the species has become increasingly abundant since the late 1980s. Separate stocks possibly exist in the North Sea and in the Skagerrak. In the North Sea, three areas with high abundance have been distinguished, suggesting three sub-populations: northwest of the Dogger Bank, one around Shetland and one in the Skagerrak/Kattegat.


There is currently no management for any of the gurnard species in the EU - there is no minimum landing size, no quota, and no effort, seasonal, temporal or technical regulations for the species. For management purposes, information is required on landings, stock structure and biological data in order to achieve sustainable exploitation in the longer term.

Capture Information

Grey gurnard is a bycatch species in demersal fisheries. Catches are largely discarded. There is a potential for damage to seabed by trawling. Trawling is also associated with discarding of unwanted fish, i.e. undersized and/or non-quota and/or over-quota species.
