Costs of Delaying Conservation: Regulations and the Recreational Values of Exploited and Co-occurring Species
研究评估了华盛顿州普吉特海湾为保护岩鱼而实施的管制措施对休闲渔业经济价值的影响，发现限制兼捕的间接成本远大于直接调整岩鱼捕捞限制的成本。
Several species of rockfishes (<i>Sebastes</i> spp.) in the Puget Sound of Washington have recently been listed under the Endangered Species Act. Bag limits for rockfishes have been restricted as a result, and recreational bycatch may prompt additional restrictions on trips targeting co-occurring species. A mixed logit model is estimated on discrete choice experiment data in order to simulate the effects of a set of regulations intended to conserve rockfish populations on recreational use values. Measures intended to limit rockfish bycatch mortality are shown to have economic impacts that are orders of magnitude larger than a direct adjustment in rockfish regulations. <i></i>
