Upwelling ecosystems are productive fishing grounds, contributing 30%to the world’s catch of marine fish. A set of seven trophic mass balance models of productivesubsystems of the four largest upwelling areas is used to demonstrate key features of themodeling process and the analysis of the models using some flow network techniques. Themodels describe trophic interactions in the northern Humboldt Current (4°–14°S), thenorthern Benguela Current (15°–35°S), the southern Canary Current (12°–25°N), and theCalifornia Current (28°–43°N), focusing on different biological regimes in the 1970s and1980s. The straightforwardness of the method is emphasized as a coherent basis for moresophisticated modeling approaches. One major advantage over more traditional assessmentmethods is that the fishery is explicitly tied into the full set of species interactions, and itsimpact can thus be readily compared to that of other piscivores in the ecosystem.
