calc_smolt: Smolt production

In salmonMSE: Management Strategy Evaluation for Salmon Species

Smolt production

Description

Calculate smolt production from base stock-recruit parameters and fitness loss

Usage

calc_smolt(
  N1,
  N2 = N1,
  kappa,
  capacity,
  Smax,
  phi = 1,
  tau = 1,
  fitness_loss = 1,
  SRrel = c("BH", "Ricker"),
  per_recruit = FALSE
)

Arguments

N1	Egg production for the density-independent component of the stock-recruit relationship. Can be the number of spawners if phi = 1 and Smax is in units of spawners.
N2	Egg production for the density-dependent component of the stock-recruit relationship (only used if per_recruit = FALSE)
kappa	Base productivity parameter
capacity	Base capacity parameter if SRrel = "BH"
Smax	Base Smax parameter if SRrel = "Ricker"
phi	Unfished egg per smolt (1/phi corresponds to the one-to-one adult/spawner replacement line)
tau	Unfished spawner per smolt
fitness_loss	Survival term to reduce smolt production due to fitness, between 0-1
SRrel	Character for the stock-recruit function
per_recruit	Logical, whether N1 is a per recruit quantity (TRUE) or in absolute numbers (FALSE)

Value

Numeric
