Picture of Haddock

Sustainability rating two info

Sustainability overview

Fishing pressure on the haddock stock in these areas is too high. To help reduce the impact of fishing on fish stocks which are heavily fished, choose line-caught fish where available or if trawl-caught, ask for fish from boats using measures such as eliminator trawls and closed-circuit TV, and fully documented fisheries (FDF) to protect them and reduce bycatch and discarding. There is a seine and trawl fishery (Scottish Fisheries Sustainable Accreditation Group (SFSAG)) for haddock in the North Sea certified as an environmentally responsible fishery by the Marine Stewardship Council (MSC) in October 2010. Certified and therefore fully traceable haddock is the best choice for this fishery.


Haddock is a cold-temperate (boreal) species. It is a migratory fish, found in inshore shallow waters in summer and in deep water in winter. Smaller than cod, it can attain a length of 70-100 cm and can live for more than 20 years. It spawns between February and June, but mostly in March and April. In the North Sea, haddock become sexually mature at an age of 3-4 years and a length of 30-40 cm. Maturity occurs later and at greater lengths in more northern areas of its range.

Stock information

The Northern Shelf haddock stock was previously assessed as two separate stocks (North Sea and Skagerrak and West of Scotland). Based on evidence that the stocks are not biologically distinct they are now being assessed as one.

Fishing mortality (F) has been fluctuating above FMSY for most of the time-series and is above FMSY in 2017. Spawning-stock biomass (SSB) has been above MSY Btrigger in most of the years since 2002. Recruitment since 2000 has been characterized by a low average level with occasional larger year classes, the size of which is diminishing.
ICES assess that fishing pressure on the stock is between FMSY and Fpa; SSB is above MSY.
ICES advises that when the MSY approach is applied, total catches in 2019 should be no more than 35 761 tonnes (51 037 tonnes in 2018; 39,461 tonnes in 2017; 74,854t in 2016; 54,580t in 2015).

There is currently no agreed management plan for haddock for the full stock area. A management plan for the whole new assessment area now needs to be developed, taking into account the need to protect local components of the stock. An EU multiannual management plan (MAP) has been proposed for this stock. The landing obligation has been in place since 2016. Despite this discarding still takes place. The estimated discard amount is 7029 tonnes in 2017 (approximately 17.6%), based on observer data.

Capture Information

Criterion score: 0.5 info

Longlining produces less bycatch and fewer discards than trawls. Since haddock is mostly taken in mixed fisheries with cod and whiting, ICES scientists have advised that fishing for haddock should take place without bycatch or discards of cod. The minimum landing size for haddock in EU waters is 30cm (27cm in Skaggerak/Kattegat).
