ICES has issued advice on fishing opportunities for Norway pout in the North Sea, Skagerrak, and Kattegat in 2022/23
The International Council for the Exploration of the Seas (ICES) has issued its advice on fishing opportunities for Norway pout in Subarea 4 and Division 3.a: North Sea, Skagerrak, and Kattegat in 2022/23.
ICES advises that when the MSY approach is applied, catches from 01 November 2022 to 31 October 2023 should be no more than 116,823 tonnes.
On the stock development over time for Norway pout, ICES found that the pawning-stock size is above Bpa and Blim; no reference points for fishing pressure or for MSY Btrigger have been defined for this stock.
Norway pout is a short-lived species. Recruitment is highly variable and strongly influences both the spawning-stock and total biomass. The ICES approach to MSY-based management for short-lived species has been used here in the form of an escapement strategy based on a stochastic forecast, i.e. to maintain, with 95% probability, SSB above Blim after the fishery has taken place. This includes an Fcap at 0.7, which was not required this year because the advised F is below 0.7.
For the implementation of the escapement strategy SSB is calculated at the beginning of quarter 4 as a proxy for SSB at spawning time (quarter 1).
The catch forecast is for the period 01 October to 30 September. ICES considers that this forecast sufficiently approximates the TAC period and that it can be used directly for management purposes for the period 1 November 2021–31 October 2022.
For 2021, ICES estimates that the catch for Norway pout in Subarea 4 and Division 3.a was 71,954 tonnes.
