Abstract
In many species, like the Cape Rock Lobster (Jasus lalandii), the life cycles of males and
females differ. This may motivate the use of two-sex models in a stock-assessment analysis.
It is also true for this resource, that juveniles do not reach sexual maturity immediately.
Therefore a delay-difference model is appropriate. In this study we follow a bio-economic
approach and use a two-sex delay-difference model to determine a maximum economic yield
strategy. Thus we determine an economic optimum steady state solution at which to harvest
this resource subject to the biological constraints of the species.
