The stock is declining , and now below recommended levels. Fishing pressure is at sustainable levels but above the management plan target. The stock is managed by a joint plan, which takes into account the 'straddling' nature of this stock (the fact that the herring cross and are fished through international boundaries during their migration), and it is in line with the precautionary approach. The fishing methods are relatively clean, although there is little information on bycatch, it is thought to be small in most fisheries. The fishery was certified as an environmentally responsible fishery by the Marine Stewardship Council (MSC) in 2009.
Herring belongs to the same family of fish (clupeids) as sprat and pilchard. It can grow to greater than 40cm, although size differs between 'races' (distinct breeding stocks). Most herring landed are around 25cm. Herring are sexually mature at between 3-9 years (depending on stock) and populations include both spring and autumn spawners. At least one population in UK waters spawns in any one month of the year. Herring have an important role in the marine ecosystem, as a transformer of plankton at the bottom of the food chain to higher trophic or feeding levels, e.g. for cod, seabirds and marine mammals. It is also considered to have a major impact on other fish stocks as prey and predator and is itself prey for seabirds and marine mammals in the North Sea and other areas. Herring spawning and nursery areas are sensitive and vulnerable to anthropogenic or human influences such as sand and gravel extraction.
Norwegian spring-spawning herring is a widely migratory stock. The feeding grounds of the adults are in the Norwegian Sea. Spawning takes place in late winter and early spring along the Norwegian coast.This widely distributed and migratory or straddling stock is managed under a joint plan by the EU, Norway, Iceland, Faroe Island and Russia. The SSB is declining and estimated to be below the precautionary biological limit (Bpa) in 2013. The stock is being fished at a sustainable level but above the level recommended by the Management Plan. Scientists advise catches in 2015 should be no more than 283,013t. The fisherywas certified as an environmentally responsible fishery by the Marine Stewardship Council (MSC) in 2009.
A long-term management plan was agreed by the EU, Faroe Islands, Iceland, Norway, and Russia in 1999. The managment plan aims to constrain harvesting within safe biological limits and is designed to provide sustainable fisheries in the long-term. The plan is evaluated by ICES as being consistent with the precautionary approach.
The fishery moves with the herring, following the migration from the Norwegian winter grounds to the feeding grounds of international, Icelandic, EU and Norwegian waters in summer. The fishery is entirely pelagic and has no impact upon the seabed. There is little information on its impacts on the ecosystem specifically but pelagic herring fisheries for human consumption are relatively clean in terms of bycatch, although the gears used have been associated with cetacean and seal bycatch. Discards are considered to be negligible, but some slippage (i.e. the net is slipped or the cod end opened in the water before being taken on board) is known to occur. The minimum landing size for herring in EU waters is 20cm (18cm in Skagerrak/Kattegat), maturity is at around 17cm.
