当缺乏生物数据时，例如在“数据有限”的捕捞和释放休闲渔业的情况下，当地生态知识是捕捉环境和/或资源变化的一个有价值的方法。LEK中一个强大的技术是使用关键信息提供者访谈，有选择地关注最有知识的专家，并询问他们的经验，观点和信仰。在这里，我们使用LEK从关键的线人，以获得深入的了解垂钓者和指导的角度对时间，位置和原因的骨鱼下降，以及对渔业的影响。20个深入的采访进行了最有经验的垂钓者和捕鱼指南在南佛罗里达（平均42年的经验）。大多数受访者描述了20世纪90年代（40%的受访者）和21世纪末（35%）发生的渔业下降，气候和水质被列为主要原因。数量的下降大于规模的下降，伊斯拉莫拉达是受影响最严重的地区之一，比斯坎湾受影响最小。线人描述了针对刺鱼的客户减少，转向其他渔业，以及南佛罗里达以外的地区。答复强调社会科学研究方法的贡献，特别是纳入主要利益攸关方的累积知识，以了解生态系统及其渔业。
Local ecological knowledge (LEK) is a valuable way to capture environmental and/or resource changes when there is an absence of biological data, such as in the case of ‘data-limited’ catch- and-release recreational fisheries. A powerful technique in LEK is the use of key informant interviews that selectively focus the most knowledgeable experts, and queries them about experiences, perspectives and beliefs. Here, we used LEK from key informants to obtain an in-depth understanding of angler and guide perspectives on the timing, placement and causes of bonefish decline, and effects on the fishery. Twenty in-depth interviews were conducted with the most-experienced anglers and fishing guides in South Florida (average 42 years of experience). Most respondents described a decline in the fishery that occurred over the 1990s (40% of respondents) and late 2000s (35%), with climate and water quality listed as top causes. Declines in number were larger than the declines in size, with Islamorada being one of the most impacted areas, and Biscayne Bay least impacted. Informants described declines in clientele targeting bonefish, shifts to other fisheries, and to locations outside South Florida. Responses emphasize the contribution of social science research methods, especially incorporating the cumulative knowledge of key stakeholders, to the understanding of ecological systems and their fisheries.
