In MixME, discards are calculated from the proportion of catch retained (the landings fraction) and over-quota discarding. The discards given by the landings fraction are calculated first, and over-quota discards are then calculated if over-quota discarding occurs. Discards numbers and weights from each process are then combined in the discards.n slot of the Operating Model. However, the total weight of over-quota discards for each stock is tracked and recorded over the course of the simulation.
