摘要

南比目鱼(parichthys lethostigma)的数量下降已经达到了路易斯安那州水域管理关注的水平。为了更好地描述路易斯安那州南比目鱼渔业的特征,我们进行了一项调查,主要有两个目标:(1)确定渔业提供的经济福利的价值;(2)评估该价值如何响应假设的监管情景而变化。根据总旅行费用估计,南比目鱼渔业在路易斯安那州沿海垂钓者中的总经济价值估计达到1.197亿美元;然而,这一价值主要来自垂钓者在沿海垂钓期间瞄准多个物种,因为南方比目鱼渔业的价值,仅考虑只瞄准该物种的垂钓者,估计达到840万美元。受访者表示强烈支持所有增加对南方比目鱼允许收获限制的监管方案。没有一个假设的监管情景会对预期的沿海钓鱼次数产生显著的行为反应,使路易斯安那州沿海渔业的经济价值保持不变。我们的研究结果说明了南比目鱼法规对路易斯安那州沿海垂钓者行为的相对无关紧要的性质。本调查收集的信息可用于指导制定可持续管理战略的决策过程,该战略得到利益相关者的支持,并保持路易斯安那州沿海渔业的强大经济价值不变。

Economic Values of Potential Regulation Changes for the Southern Flounder Fishery in Louisiana

Economic Values of Potential Regulation Changes for the Southern Flounder Fishery in Louisiana

Population declines of Southern Flounder Paralichthys lethostigma have reached levels that present management concerns in Louisiana waters. As the need for regulatory change in this fishery approaches, we conducted a survey to better characterize the Southern Flounder fishery in Louisiana, with two primary goals: (1) determining a value for the economic welfare provided by the fishery and (2) evaluating how this value might change in response to hypothetical regulation scenarios. Based on total travel cost estimates, the aggregate economic value of the Southern Flounder fishery among coastal Louisiana anglers reached an estimated US$119.7 million; however, this value primarily stems from anglers targeting multiple species during their coastal angling trips, as the value of the Southern Flounder fishery while only accounting for anglers that solely targeted this species amounted to an estimated $8.4 million. Respondents revealed strong levels of supportiveness for all regulation scenarios that increased limitations on allowable harvest for Southern Flounder. None of the hypothetical regulation scenarios led to significant behavioral responses in the expected number of coastal angling trips taken, leaving the economic value of coastal Louisiana fisheries unchanged. The results of our study illustrate the relatively inconsequential nature of Southern Flounder regulations upon the behavior of coastal Louisiana anglers. The information gathered by this survey can be used to guide the decision-making process in developing a sustainable management strategy that is supported by stakeholders and that keeps the strong economic values of coastal Louisiana fisheries intact.

期刊介绍: Marine and Coastal Fisheries: Dynamics, Management, and Ecosystem Science publishes original and innovative research that synthesizes information on biological organization across spatial and temporal scales to promote ecologically sound fisheries science and management. This open-access, online journal published by the American Fisheries Society provides an international venue for studies of marine, coastal, and estuarine fisheries, with emphasis on species'' performance and responses to perturbations in their environment, and promotes the development of ecosystem-based fisheries science and management.
