Summary
All models are wrong, some models are useful.
George Box (Box and Draper 1987)BIONIC FISHERIES MODELS
In the last chapter, we saw how extant SS models can be expanded to SS add-on and MS models, maintaining the stock or population emphasis. In this chapter we will explore models that can certainly do some of that, but will primarily emphasize models from an aggregate taxonomy and systemic perspective.
In some instances, after a triage and heuristic exercise has been executed (Table 4.1), it can become clear that a SHIRCS perspective is required to adequately capture system or community dynamics and to adequately address the management issues at hand. As we have noted (Table 7.3), there is no shortage of modeling approaches for the range of issues facing us in the implementation of EBFM. But what are the methods and analytical approaches necessary to facilitate such a broader view and to provide information to support an EBFM decision framework? As we explore the answer to that question, we will also return to some of the themes noted in Chapter 6, elucidating more explicitly some of the outputs from these models as they might be used to delineate ecosystem overfishing.
