This yield rate is given in grams per year. It is calculated at each time step saved in the MizerSim object.
An object of class
If called with a MizerParams object, an array (gear x species) with the yield rate in grams per year from each gear for each species in the model. If called with a MizerSim object, an array (time x gear x species) containing the yield rate at each time step.
For details of how the yield rate is defined see the help page of
yield <- getYieldGear(NS_sim) yield["1972", "Herring", "Herring"] #>  80002050975 # (In this example MizerSim object each species was set up with its own gear)
