ypr (version 0.6.0)

ypr_yields: Yields

Description

Calculates the yield(s) for a population based on one or more capture rates.

Usage

ypr_yields(
  object,
  pi = seq(0, 1, length.out = 100),
  Ly = 0,
  harvest = TRUE,
  biomass = FALSE
)

Value

A numeric vector of the yields.

Arguments

object

The population or populations.

pi

A vector of probabilities of capture to calculate the yield for.

Ly

The minimum length (trophy) fish to consider when calculating the yield (cm).

harvest

A flag specifying whether to calculate the yield for harvested fish or captures.

biomass

A flag specifying whether to calculate the yield in terms of the biomass versus number of individuals.
