ypr_tabulate_fish

An object of class <code><a rd-options="=ypr_population" href="/link/ypr_population()?package=ypr&version=0.5.2&to=%3Dypr_population" data-mini-rdoc="=ypr_population::ypr_population()">ypr_population()</a></code>.

population

A positive integer of the width of the bins for grouping.

binwidth

Produces a data frame of the number of fish in the
'Survivors', 'Spawners', 'Caught', 'Harvested', 'Released' and 'HandlingMortalities' categories by
'Length', 'Age' or 'Weight' class.

An implementation of equilibrium-based yield per recruit
methods. Yield per recruit methods can used to estimate the optimal
yield for a fish population as described by Walters and Martell (2004)
<isbn:0-691-11544-3>. The yield can be based on the number of fish
caught (or harvested) or biomass caught for all fish or just large
(trophy) individuals.
