A dynamic predator - prey model for fishery resources: a case of Lake Kasumigaura
Received 5 January 1981
Abstract. A dynamic model for fishery resources with predator - prey relationships is constructed based on observational data and research findings for Lake Kasumigaura, Japan. The analysis of the stationary state as well as the sensitivity analysis shows that the use of diesel-powered trawling, which enables the large-scale catch of prey species in comparison with the traditional method of sailing trawling, may lead to the extinction of predator as well as prey species once the trawling efficiency in the catch of prey species is improved beyond the present level, provided that fishermen behave so as to maximize their profits subject to the restriction of operation time.
