Sustainability rating two info

Sustainability overview

The spawning-stock biomass (SSB) has increased significantly since 2006 and is well above historical estimates. Fishing mortality has decreased sharply in recent years and has been below F MSY since 2012. Discards of young hake can be substantial in some areas and in some fleets and measures are required to address this. Hake is a late maturing fish. Avoid eating immature fish below about 50cm, and during their breeding season, February to July, although note spawning will occur at different times in localised areas within this period throughout the stock range.

The Cornish hake gill net fishery was certified by the Marine Stewardship Council (MSC) as a sustainable fishery in June 2015. MSC certified Scottish whitefish fisheries include hake, plaice, saithe, whiting and haddock. Hake from these fisheries is the best sustainable choice currently available.

Biology

Hake belongs to a group of fish known collectively as Merluccidae. There is only one species, European hake, found in European seas. European hake is widely distributed over the Northeast Atlantic shelf. Hake is a top predator and cannibalistic. It is a late maturing fish, spawning from February to July in northern waters. There are two major nursery areas: the Bay of Biscay and off southern Ireland. As they approach maturity, hake move into deeper waters offshore. Hake can attain a length of 100-180 cm, with a weight of 11-15 kg. Females mature at 5-6 years at about 50 cm.

Stock information

There was a pronounced stock decline in the 1980s, with spawning-stock biomass (SSB) hitting a historical low in the early 1990s. A recovery plan was introduced for the stock in 2004.
The spawning-stock biomass (SSB) has increased substantially since 2006 and is well above historical estimates. Fishing mortality (F) has decreased markedly after 2005 and has been below FMSY since 2012. The two most recent recruitment (R) estimates are above the average of the time-series.
ICES assesses that fishing pressure on the stock is below FMSY, Fpa, and Flim and that 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 142 240 tonnes.

Management

Criterion score: 0.5 info

A recovery plan for the stock was agreed by the EU in 2004. The plan has not yet been evaluated by ICES and is currently using target values that are now considered no longer appropriate. The European Commission has proposed a multiannual management plan (MAP) for the Western Waters, which is not yet finalised.
Discarding of juvenile hake (undersized and above minimum size) can be substantial in some areas and fleets. Measures to improve selectivity towards larger fish is required to reduce discarding of juvenile hake which can be substantial.
In the most recent period, discarding of large individuals increased because of quota restrictions in certain fleets. In 2017, observed discards decreased and a rate of 6% estimated for discards in 2017. Some fleets fishing this stock have been under the EU landing obligation since 2016.

Capture Information

Criterion score: 0.5 info

Hake is caught in mixed fisheries together with megrim, anglerfish and Nephrops. Discards of juvenile hake can be substantial in some areas and fleets. Mortality of small fish could be reduced by introducing measures to increase gear selectivity and reduce catches of unwanted fish, e.g. by increasing mesh size. Since the introduction of high vertical opening trawls in the mid-1990s, no significant changes in fishing technology have been introduced. There is a potential for damage to the seabed from trawling. Trawling is also associated with discarding of unwanted fish, i.e. undersized and/or non-quota and/or over-quota species. The minimum landing size for hake in EU waters is 27cm (30cm in Skagerrak/Kattegat). The size at which approximately 50% of females mature however, is 50+ cm, which means that the MLS should probably be reviewed.
