Obtain stock-recruitment relationship

Calculate recruitment from spawning stock biomass using Beverton-Holt or Ricker.

Usage

get_stock_recruitment(sr_type = 1, SSB0, SSB, logit_h)

Arguments

sr_type

an integer specifying stock-recruitment type (1 = Beverton-Holt, 0 = Ricker).

SSB0

the unfished spawning stock biomass (tonnes).

SSB

the current spawning stock biomass (tonnes).

logit_h

the logit-transformed steepness of the stock-recruit relationship.

Value

a numeric value representing the stock-recruitment scalar.

Examples

get_stock_recruitment(sr_type = 1, SSB0 = 1000, SSB = 100, logit_h = qlogis(0.99))
