make_spawnrecruit: Make age-specific proportion of spawners in population

In danStich/anadrofish: Anadromous Fish Population Responses to Habitat Changes

Make age-specific proportion of spawners in population

Description

The purpose of this function is to make age-specific recruit to spawn probabilities for rivers listed in get_rivers using built-in data sets for region-specific max_ages and maturity.

Usage

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

Arguments

river	River for which spawn recruit probabilities are requested.
sex	Sex of fish. If not specified, then mean of male and female spawn recruit probabilities are returned.
species	Species for which rivers are returned Choices include American shad ("AMS"), alewife ("ALE"), and blueback herring ("BBH"). If species is "ALE" or "BBH" then this function calls make_spawnrecruit_rh.
custom_habitat	A dataframe containing columns corresponding to the those in the output from custom_habitat_template. The default, NULL uses the default habitat data set for a given combination of species and river.

Value

A numeric vector of length = length(max_age) depending on maximum age in the selected river by region and species.
