Calculate F/B Reference Points via SPR Methods

Calculate fishing mortality and biological fisheries reference points via traditional SPR methods.

calculate_spr_refpoints(nages, dem_params, joint_selret, spr_target, rec)

Arguments

nages

number of ages in age structure

dem_params

list of demographic parameters subset to a single year

joint_selret

list of total selectivity and retention across all fleets, weighted by relative fleet-specific fishing mortality (compute using `calculate_joint_selret`)

spr_target

desired SPR proportion

rec

recruitment used to calculate BRP

Value

list of Fref and Bref

Examples

if (FALSE) { # \dontrun{
calculate_spr_refpoints(nages, dem_params, joint_selret, spr_target, rec)
} # }
