Make spawnrecruit vectors for river herring — make_spawnrecruit

Simulate proportion of population that is mature spawners from sex-specific maturity schedules for river herring in maki_pars.

Usage

make_spawnrecruit_rh(
  river,
  sex = c("male", "female"),
  species = c("ALE", "BBH"),
  custom_habitat = NULL
)

Arguments

river: River for which maximum age is needed.
sex: A character indicating "male", "female", or "Pooled" sex for fish.
species: A character indicating species of river herring, either "ALE" for alewife or "BBH" for blueback herring.
custom_habitat: A dataframe containing columns corresponding to the those in the output from custom_habitat_template.

Value

A numeric vector containing a single realization for proportion of mature fish at each age, from age 1 to maximum age.

Details

The primary use of this function is to simulate proportion of mature spawners at each age in a population of river-herring based on region-specific probabilities of maturation at each age estimated from the Maki (YEAR) method in ASMFC (2024).

Examples

make_spawnrecruit_rh(river = "Upper Hudson", species = "BBH", sex = "female")
