Economic modelling for trout management: an introduction and case study

Trout stocks in Lake Taupo, New Zealand are managed by the Department of Conservation to sustain the fishery and enhance angler opportunity. Efficient management requires funds. These funds are generated from license sales. The revenue from license sales is determined by demand for the licenses and their price. This study reports estimates of the price elasticity of demand for trout licenses. These estimates show how license sales, revenue, royalties and funds for stock enhancement change with price changes and different elasticity estimates.
