The territory of Puán County encompasses 133 shallow lakes, which resources are barely used. Technical knowledge of the shallow lakes is limited, hence the management policy currently being applied is generic. The aim of this paper is to make a primary proposal for the strategic use of the fisheries, supported by an expeditious diagnostic of various environments. Each shallow lake exhibits particular characteristics. The CPUE ranges from 0 to very abundant. In general, the rate of exploitation is low, producing an excellent yield and high quality fish resources. The trophic chain is short, with relevant zooplankton size and density, sustaining an abundant pejerrey Odontesthes bonariensis population. The services offered to the anglers in the shores are few or nonexistent. Tourism development is scarce in spite of the strong potential. Weaknesses and strengths are analyzed considering different parameters and situations. The use of resources through sport fishing is proposed, targeting on high-income fishermen looking for high quality pejerrey catch in a near pristine shallow lake and enjoying privacy. Such a fisherman demands quality and professionalism in the services received, as well as personal or exclusive attention by providers. On the other hand, those shallow lakes not selected for a sport fishing circuit, can be managed by the local government allowing the catch of pejerrey, controlling the correct use of gill nets, creating more jobs, and also providing fish to the town’s popular kitchens feeding the needy. The potential emergent problems contemplated in the execution of the project are listed and compared to the current situation.
