calc_pwild

calc_pwild_age

Calculate the proportion of wild spawners from a time series of spawners<ul>
<li><code>calc_pwild()</code> is the simple calculation based on the proportion of hatchery spawners</li>
<li><code>calc_pwild_age()</code> performs the calculation weighted by age class fecundity</li>
</ul>

Simulation tools to evaluate the long-term effects of salmon management strategies, including a combination of habitat, harvest, and
habitat actions. The stochastic age-structured operating model accommodates complex life histories, including freshwater survival across
early life stages, juvenile survival and fishery exploitation in the marine life stage, partial maturity by age class, and fitness impacts of
hatchery programs on natural spawning populations. 'salmonMSE' also provides an age-structured conditioning model to develop operating models
fitted to data.
