Bio-Economic Models for Measuring the Economic Effects of Hydropower on Anadromous Fish Populations in the Pacific Northwestby John B. Loomis, Univ of California, Davis, CA, USA,
Abstract: An empirical model is presented for predicting the net economic value of changes in recreational catch of salmon and steelhead in Oregon, Washington and Idaho associated with construction and operation of hydroelectric dams. Valuation of recreational fisheries is performed using a multi-river Travel Cost Method demand model in which recreational fish catch enters as an independent variable directly affecting number of angler trips and benefits. These models estimate a river specific marginal value per fish caught and therefore avoid many of the criticisms of past economic valuation studies. Both freshwater and ocean recreational fishing are modeled consistent with the U. S. Water Resources Council Principles and Guidelines.
