"Do we really need models, however complete, to embark on ecosystem management? How about starting with reducing or, where still feasible, preventing river-borne pollution, municipal, agricultural, and industrial effluents? And providing more protection to inshore, and along-shore habitats? Can’t we do all these and more, apart from, but together with fisheries management without models?
Now about models. I’m most certainly not an expert on modelling, but I have very strong opinion on applying models where they do not belong. When a (mathematical/statistical) model is proposed it should be examined as to whether it comprises all the important elements required to generate results and whether and to what degree are the data fed to those elements sufficient and trustworthy.
I think that the key problem with economic, ecosystem, fisheries and any other management models of whatever sort is that they themselves need to be wisely managed. What I mean is that whenever any such model is about to be applied to provide practical solutions or forecasts, its should be peer reviewed (by quite independent panel) for the following: is it correctly designed; does it fit the situation to which it is supposed to be applied; if “yes” to the latter, what is going to be its reliability level with respect of providing appropriate answer/solution.
I trust that, provided that data and information collection would develop to feed computers with the right stuff, with continually improving computing power also models would be improving.
For, as the late Dr.Bill Silvert wrote: a model is never complete…"
