Advice Sentence
*
ICES advises that when the maximum sustainable yield (MSY) approach is applied, catches in 2026 should be no more than 74 214 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 2026. Catches of North Sea horse mackerel in the fishery for western horse mackerel in Division 7.e should be avoided to support the recovery of the North Sea stock.

Advice value for 2026 relative to advice value for 2025 (75 545 tonnes).
***
The percentage probability of SSB being below Blim in 2027. 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.
