Report of the Workshop on the determination of reference points for Norwegian Spring Spawning Herring (WKNSSHREF)
The Norwegian spring spawning herring (NSSH) was benchmarked in 2016 (ICES, 2016) and XSAM was accepted as the standard assessment model for this stock. The reference points were to be evaluated during the benchmark. However, due to time constraint only B lim was evaluated. The conclusion was that B...

Following that decision, the coastal states requested ICES to “to finish the process of re-evaluation of the reference points for Norwegian spring-spawning (Atlanto-Scandian) herring during the first quarter of 2018. Provided that ICES has completed their work on the reference points, the delegations agreed to meet before 15 May 2018 to discuss a possible revision of the long-term management strategy.” In order to meet the request, a workshop was set up by ICES and took place in ICES headquarters 10-11th April 2018. The workshop was attended by 12 participants. XSAM simulations were conducted for the NSSH. These followed the ICES advice technical guidelines as published on 20th of January 2017 (ICES 2017) for the estimation of the precautionary and MSY reference points.
