Ling is a member of the cod family. It is long and slender with a mottled olive and brown colour. The flanks are lighter with brownish blotches and the belly is white. It has delicious white flesh and is excellent in a range of dishes.
Ling is an eel like member of the cod family. Stocks of ling appear to be relatively healthy in our waters although there is little research published. Fishermen landing to Looe and Plymouth report good stocks of ling. The latest ICES report shows that fishing effort is below dangerous levels and that there is a general positive trend helping the stocks at present. Ask for ling caught by inshore Cornish day boats uisng gill nets or demersal trawls.

Gill nets are lightweight nets made of nylon (monofilament) fishing line that are anchored to the seabed and are used to catch fish by entangling the gills.Learn more

Demersal trawls are large nets that are pulled through the water with the bottom edge of the net touching the seabed. At each edge the net is pulled open by metal ‘trawl doors’. Sometimes referred to as Otter trawling.Learn more

Beam trawls are nets attached to a steel beam that holds the net open. The belly of the net is made of chains and the upper surface of the net is mesh. Beam trawlers pull two nets along the seabed simultaneously.Learn more
Cornwall Good Seafood Guide rates fish on sustainability using a scale of 1 to 5.
1, 2 and 3 are recommended, Fish to avoid are rated 5.
We use the system devised by the Marine Conservation Society (MCS) so our scores are comparable with the scores produced by MCS for the UK and fisheries from all around the world. For more information on scoring click here.
Ling grow extremely large, up to 2 meters in length and resemble a cross between a conger eel and a cod. Ling are slow growing and can live for up to 25 years. They are seen by divers occasionally but the majority are found at depths of between 100m and 400m deep. Ling are active predators that feed on other fish such as cod and herring and crustaceans such as crabs and lobster. Ling spawn between February and May. Ling has a high vulnerability to over fishing (77 out of 100 ref Cheung et al 3005) Ling prefer cold waters and are migratory and widely distributed around the North east Atlantic.
Stocks have not been studied in great detail so we dont know how healthy the stocks are, but infomation from the fishing industry states that catches have been steady for the past five years and the stocks appear healthy. The latest ICES advice for the whole of the North Altlantic suggests that fishing effort is below sustainable levels but stock biomass is not known. Although landings to Cornwall of ling are around 300 tonnes per year this is a tiny fraction (approx 2%) of the landings caught by the European and Faroes fleet operating to the North of Scotland. Studies of these large scale longline and trawl fisheries show that Ling stocks are stable and possibly increasing. Landings to Cornwall have decreased significantly since the 1990’s but this may be due to reduced effort. Longlining targeting ling is no longer carried out and the trawler fleet has reduced in size. Catch per unit effort data suggests that stocks are either stable of increasing.
Ling catches are restricted through Quotas set by the EU Common fishing Policy. No specific management objectives are known to ICES. The legal minimum landing size for ling in EU waters is 63cm. However ling matures at 80-90cm, so this is an inadequate measure to protect immature fish.
Ling are caught by beam trawlers, netters and demersal trawlers. Longlining targeting ling and hake, once a mainstay of the Newlyn fleet is now a rare practice with many boats having switched to netting and trawling in the 1970’s and 80’s. All over 10m vessels netting outside the 6nm limits now have to use dolphin scaring pingers to reduce the chances of accidentally catching porpoises or dolphins in the nets.
This simple dish is delicous and easy to prepair. And is best using fresh cornish squid!
