Advice Sentence
*
ICES advises that when the maximum sustainable yield (MSY) approach is applied, catches in 2025 should be no more than 75 545 tonnes. North Sea horse mackerel is caught in a mixed fishery with western horse mackerel in Division 7.e, and ICES advises that there should be zero catch of North Sea horse mackerel in 2025. Catches of North Sea horse mackerel in the fishery for Western horse mackerel in Division 7.e should be minimized to support the recovery of the North Sea stock.

***
The percentage probability of SSB being below Blim in 2026. This probability relates to the short-term probability of SSB <; Blim and is not comparable to the long-term probability of SSB <; Blim tested in simulations when estimating fishing mortality reference points.
