catch.n-FLQuant-method: catch.n calculation method

In flr/FLCore: Core Package of FLR, Fisheries Modelling in R

catch.n calculation method

Description

Calculate catch.n (catch-at-age/length) from abundances, F and M using the catch equation

Usage

## S4 method for signature 'FLQuant'
catch.n(object, harvest, m)

Details

The catch-at-age/length, commonly found in the catch.n slot of an FLStock object, can be simply calculated from abundances-at-age/length, and natural and fishing mortalities-at-age/length by applying the catch equation

C = N \cdot F \frac{F}{M+F} \cdot (1 - {\rm e}^(-M-F))
