For Whiting stocks around Ireland, FMSY is based on provisional proxies within the range of fishing mortalities consistent with MSY. For VIa West of Scotland and Irish Sea Whiting MSY reference points are not defined and PA reference points are used. For Celtic Sea Whiting MSY Btrigger is set at Bpa. In the future when there are sufficient observations of SSB fluctuations associated with fishing around FMSY, the MSY Btrigger should be re-estimated to correspond to the lower boundary of the range of stock sizes associated with MSY.

Both anglerfish stocks are data limited and no reference points have been defined. Trends are detected by y(i, i-1)/y(i-2, i-3, i-4) – survey biomass of the last two years divided by the survey biomass of the previous three years in %. This value gives an indication of how much the biomass of anglerfish species has changed in the last five years.

For Haddock stocks around Ireland, FMSY is based on provisional proxies within the range of fishing mortalities consistent with MSY. For VIa West of Scotland and VIb Rockall Haddock FMSY proxy is based on that of North Sea Haddock and MSY Btrigger is set at Bpa. For Celtic Sea Haddock VIIb-k FMSY proxy is based on Fmax and MSY Btrigger is set at Bpa. MSY reference points are not defined for Irish Sea Haddock. Overall status is based on a “one out all out” approach.

For Herring stocks around Ireland, FMSY is based on simulations under different productivity/management regimes for Irish Sea Herring (VIIaN), Celtic Sea herring (VIIaS and VIIghjk), northwest of Ireland Herring (VIaS VIIbc) and Herring in VIaN.

Biomass reference points are as follows: For Irish Sea Herring, MSY Btrigger is set at Bpa, Celtic Sea herring and northwest of Ireland herring use Bpa. For west of Scotland Herring (VIaN) biomass limits are set at Blim which is the lowest observed biomass.

For fish stocks around Ireland, FMSY is based on provisional proxies within the range of fishing mortalities consistent with MSY. For northeast Atlantic mackerel MSY Btrigger is associated with SSB with high long-term yield and low probability of stock depletion based on management strategy evaluation (ICES, 2008). FMSY is associated with this reference point.

For sole stocks around Ireland, FMSY is based on provisional proxies within the range of fishing mortalities consistent with MSY. For VIIa Sole MSY Btrigger defaults to the value of Bpa. FMSY is a provisional proxy based on stochastic simulations. In VIIf-g FMSY is also a provisional proxy based on stochastic simulations. MSY Btrigger is set to Bpa. MSY Btrigger for Sole in VIIh-k is not defined and FMSY is a provisional proxy based on WGCSE 2010 estimate of Fmax.
