Sustainability overview

The haddock stock at Rockall is an entirely separate stock from that on the continental shelf of the British Isles. Haddock there have lower growth rates and reach a lower maximum size than other haddock populations in the Atlantic. The spawning-stock biomass (SSB) has increased from the lowest observed in 2014 and is now estimated to be above MSY Btrigger. Fishing mortality (F) has declined over time and is now below the required level and the stock harvested at a sustainable level. The Scottish Fisheries Sustainable Accreditation Group (SFSAG) Rockall haddock was certified as a responsibly managed and sustainable fishery by the Marine Stewardship Council (MSC) in July 2018.

Biology

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 haddock stock at Rockall is an entirely separate stock from that on the continental shelf of the British Isles. Haddock there have lower growth rates and reach a lower maximum size than other haddock populations in the Atlantic.

The Spawning stock biomass (SSB) has increased from the lowest observed in 2014 and is estimated to be well above MSY Btrigger. Fishing mortality (F) is highly variable; in 2017 it is below FMSY. Recruitment during 2008-2012 is estimated to have been extremely weak, but has improved since. Recruitment in 2017 and 2018 is estimated to be above average.
ICES assesses that fishing pressure on the stock is below FMSY, Fpa, and Flim, and that the spawning stock size is above MSY Btrigger, Bpa, and Blim.
ICES advises that when the MSY approach is applied, catches in 2019 should be no more than 10 469 tonnes (5163 in 2018; 4690 in 2016; 4310t in 2015; 1620 t in 2014).

Capture Information

Criterion score: 0.5 info

Rockall haddock is taken in directed fisheries and as bycatch in demersal trawl (98%) and longline (2%) fisheries. The fisheries are mixed together with monk and megrim, and some of the fisheries include substantial catches of blue whiting and grey gurnard, for example.
