|
* This class calculates the growth of the stock, according to the different growth functions derived from the GrowthCalcBase class. Since the growth calculations can take place on a coarser scale than the stock is defined on, the calculated growth is then interpolated to take the length group of the stock into account. This growth is then implemented by moving the fish up from the old length groups to the new length groups, taking care to ensure that the fish that would move to beyond the largest length group are kept in the plus group.
