With the rise of interest in biodiversity, a few scientists have endeavoured to quantify the nature and importance of biodiversity services. Their work has considered the relationship between biodiversity and such phenomena as ecosystem productivity, soil fertility, community stability, sustainability and resiliency. An excellent.

This requires the specification of an appropriate production function describing the relationship between fish biodiversity as an input and fish catch as an output. In this paper it is assumed that the effect of species diversity on fish productivity may be captured by the introduction of an additional term into the fisheries.
