Management of shared fish stocks: coastal state agreed records 2023

Agreed records of coastal state consultations on the management of shared stocks in the north-east Atlantic in 2023.


Annex I

Long-term management strategy for the Norwegian spring-spawning (Atlanto-Scandian) herring stock

1. The Parties agree to implement a long-term management strategy for the fisheries on the Norwegian Spring Spawning (Atlanto-Scandian) Herring stock, which is consistent with the precautionary approach and the MSY approach, aiming at ensuring harvest rates within safe biological limits.

2. For the purpose of this long-term management strategy, in the following text, TAC” means the total allowable catch as agreed by Coastal States.

3. As a priority, the long-term management strategy shall ensure with high probability that the size of the stock is maintained above Blim.

4. In the case that the spawning biomass is forecast to be above or equal to Btrigger (=Bpa) on 1 January of the year for which the TAC is to be set, the TAC shall be fixed to a fishing mortality of Fmgt=0.14.

5. Where the rules in paragraph 4 would lead to a TAC, that deviates by more than 20% below or 25% above the TAC of the preceding year, the Parties shall fix a TAC that is respectively no more than 20% less or 25% more than the TAC of the preceding year. The TAC constraint shall not apply if the spawning biomass at 1 January in the year for which the TAC is to be set is less than Btrigger

6. In the case that the spawning biomass (SSB) is forecast to be less than the precautionary biomass (Btrigger) but above or equal to Blim on 1 January of the year for which the TAC is to be set, the TAC shall be fixed at a level that is consistent with a fishing mortality given by:

Target F = 0.05 + [(SSB -B1im)*(Fmgt – 0.05) I (Btrigger -Blim)]

7. In the case that the spawning biomass is forecast to be less than Blim on 1 January of the year for which the TAC is to be set, the TAC will be fixed corresponding to a fishing mortality F=0.05.

8. Each Party may transfer to the following year unutilised quantities of up to 10% of the quota allocated to it. The quantity transferred shall be in addition to the quota allocated to the Party concerned in the following year.

9. Each Party may authorize fishing by its vessels of up to 10% beyond the quota allocated. However, this shall not apply if the stock is forecast to be under Btrigger at the end of the TAC year. All quantities fished beyond the allocated quota for one year shall be deducted from the Party’s quota allocated for the following year.

10. The Parties, on the basis of ICES advice, shall review this long-term management strategy at intervals not exceeding five years. The first such review shall take place no later than 2023, in time for ICES to issue advice for 2024.
