Exploitation Probability

Source: R/exploitation.R
ypr_exploitation.Rd

Converts capture probabilities into exploitation probabilities based on the release and handling mortality probabilities where the probability of exploitation includes handling mortalities. The calculation assumes that a released fish cannot be recaught in the same year.

Usage

ypr_exploitation(object, pi = ypr_get_par(object))

Arguments

object

The population or populations.

pi

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

Value

A vector of exploitation probabilities.

Details

In the case of no release (or 100% handling mortalities) the exploitation probability is identical to the capture probability. Otherwise it is less.

Examples

ypr_exploitation(ypr_population(pi = 0.4))
#> [1] 0.4
ypr_exploitation(ypr_population(pi = 0.4, rho = 0.6, Hm = 0.2))
#> [1] 0.208
