While the conceptual framework of the zooplankton compartment includes a number of commonly accepted processes, the representation of interactions in the formulation is perhaps the most complex to be found in the model. For example, conservation of mass in the grazing process, and the tracking of egg and juvenile development throughout time lags that may become quite long, necessitated reasonably sophisticated algorithms. Further complexity was required due to a more precise predictor-corrector integration method (see Chap. 7), which separates the estimation of the preferred ingested ration from the metabolic use of the assimilated ration in the flow of the program. In this chapter, the conceptual rationale for the formulations will be presented, followed by a specific account of the complications required to implement it.
