Harvest Adults Function — harvest

This function calculates the total adult salmon harvest based on various parameters. This function is called within the larger model.R file before stray rates and prespawn survival is applied.

harvest_adults(
  adult_df,
  spawner_df,
  year = year,
  spawn_habitat,
  terminal_hatchery_logic = c(T, F),
  ocean_harvest_percentage,
  tributary_harvest_percentage,
  restrict_harvest_to_hatchery = c(F, T),
  no_cohort_harvest_years = NULL,
  intelligent_habitat_harvest = c(F, T),
  intelligent_crr_harvest = c(F, T),
  crr_scaling = 2
)

Arguments

adult_df: A data frame containing information about adult salmon.
year: The target year for the harvest calculation.
ocean_harvest_percentage: The percentage of harvest from the ocean, same for all tributaries.
tributary_harvest_percentage: The percentage of harvest from tributaries, can vary by tributary.
restrict_harvest_to_hatchery: A logical vector indicating whether to restrict harvest to hatcheries for each tributary.
no_cohort_harvest_years: A vector of years where no cohort harvest is allowed.
intelligent_crr_harvest: A logical vector indicating whether to apply intelligent harvest based on Coho Retention Rate (CRR).

Value

A numeric value representing the total adult salmon harvest.
