Abstract

The aim of this paper is to develop a methodology to estimate recovery times using a wide range of published Ecopath modeled overfished data-rich fisheries that had not recovered in the North Sea, Mediterranean, and South America shelves. Recovery times were estimated by biomass increase according to the Verhulst logistic equation mathematical solution, requiring the intrinsic rate of natural increase, r, and the carrying capacity for a fishery, KE, both derived from documented fishery biological process principles. The mathematical solution indicated recovery from
