Symbol Footnotes
** Biomass 1+ in 2019 relative to Biomass 1+ in 2018 (151884 t).
*** Catch in 2018 compared to 2016 catches (22704 t).
^ This management plan has been evaluated and found to be not precautionary (ICES, 2017b)
^^ The Blim, Bpa, and MSY Btrigger options were left blank because Blim, Bpa, and MSY Btrigger cannot be achieved in 2019 even with zero catch in 2018.
