ypr_exploitation {ypr}

Exploitation Probability

Description

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.

Details

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

Value

A vector of exploitation probabilities.
