Sustainable management of marine resources

Recently, the international community has shown a strong concern about the sustainability of different fisheries around the world. Several factors can explain why some important fisheries are nowadays in a precarious situation: the overexploitation (suffered, for instance, by Chilean hake during last decades), the vulnerability of some particular species (for instance, deep water fishes such as Chilean sea bass, Orange Roughy, Alfonsino, etc.), the impact of climatic factors (which has a strong impact in some small pelagic species such as Chilean Jack Mackerel and Anchovy in the Pacific-South Hemisphere), among others. Mathematical modeling can provide rigorous and new points of view that can contribute to the solution of these problems.

Some problems related with the estimation of the trade off between differents objectives (biological v/s production) for deep-water fisheries and with the determination of recovery programs for overexploited fisheries have been studied in our group in the framework of the international cooperation network MIFIMA (Mathematics, Informatic, and FIshery MAnagement). In Chile, the team MIFIMA has been invited to organize sesions in national conferences, and to explain the developed quantitative tools to people of regulatory organisms and industrial companies.
