UNIFY vulnerable biomass method

iagomosqueira opened this issue · 1 comments

FLCore::vb methods calculate the vulnerable biomass according to either the global selectivity, as contained in harvest, or a new FLQuant, for a given fleet.

A new name is needed for the method, referring to exploitable biomass, and whether other calculations are needed.

vulnerability is important for developing observation error models, and for predicting values of CPUE for use in stock assessment models, see eqn 1 & 2
