Publication Abstract

Is the whole always less than the sum of the parts?

K.M. Brander and R.K. Mohn

We question the view that the total yield from a multispecies fishery must necessarily be less than the sum of the maximum yields of the component species, if each were optimized separately. A predator-prey model is used to show that this view depends on the assumptions which are made about predation mortality.
