Description Usage Arguments Note
The Biomass-based HCR is used in the case of the Icelandic cod and saithe. Here it is implemented such that the TAC next year is a multiplier of the target harvest rate and the observed reference biomass (i.e. that includes observation errrors).
If the Btrigger is set in the rule (Btrigger > 0) then linear reductions of fishing mortality is done relative to observed spawning stock biomass (i.e. that includes observation errrors).
