A development site in Baja California Sur Mexico is the Bay of Loreto, an emblematic place with fishing tradition and huge touristic potential. To provide useful information which can be used to improve the economic development policies of the municipality and the management plan of Loreto Bay National Park, this study characterized the fishing activity based on records, statistics from 2000 to 2016, and available publications; defined the fisheries in the study area; estimated their relative importance; and determined dynamics of the fleet operation, local knowledge, economic diversification, and socio-economic aspects of the users such as age, scholarly, income, among others. The local knowledge was obtained through the implementation of a survey and the use of databases providing statistical information and data related to the official catch landing reports (OCLR). This last data let us define the production trends of 16 years. According to the relative importance index, the finfish fishery was the most relevant; therefore, its seasons were estimated, and maps of the catch’s distribution were made. The fishing gears in use were identified, where the hand line with a hook was predominant, followed by the gill net of different mesh sizes, more applied to yellowtail fish and parrotfish, and the traps to triggerfish. Using the local knowledge, we defined the depths at which the main resources are located, and the spatial and temporal distribution of the fisheries was confirmed. We found that less than 40% of the fishermen practice alternative economic activities to fishing to supplement their income. In the finfish fishery, the most important resource is the red snapper (Lutjanus peru). We recommend considering the updating of the management program, especially the topics related to small-scale fishing within the corresponding boundary polygon, and to promote actions to encourage greater economic diversification among fishing communities.

墨西哥南下加利福尼亚州的一个开发地点是洛雷托湾，这是一个具有捕鱼传统和巨大旅游潜力的标志性地方。为了提供可用于改善市政府经济发展政策和洛雷托湾国家公园管理计划的有用信息，本研究根据记录、2000 年至 2016 年的统计数据和现有出版物对渔业活动进行了描述；界定研究区内的渔业；估计它们的相对重要性；和确定的车队运营动态、当地知识、经济多样化和用户的社会经济方面，如年龄、学术、收入等。通过实施调查和使用提供与官方渔获量上岸报告 (OCLR) 相关的统计信息和数据的数据库，获得了当地知识。最后的数据让我们定义了 16 年的生产趋势。从相对重要性指数来看，有鳍鱼类渔业的相关性最高；因此，估计了它的季节，并绘制了渔获物分布图。所使用的渔具已确定，其中带钩的手线占主导地位，其次是不同网目大小的刺网，更多地适用于黄尾鱼和鹦嘴鱼，而诱捕器则适用于触发鱼。利用当地知识，我们定义了主要资源所在的深度，并确定了渔业的时空分布。我们发现，只有不到 40% 的渔民从事渔业以外的其他经济活动以补充收入。在有鳍鱼类渔业中，最重要的资源是红鲷鱼（Lutjanus 秘鲁）。我们建议考虑更新管理计划，尤其是与相应边界多边形内的小规模渔业相关的主题，并促进采取行动鼓励渔业社区的经济多样化。
