Abstract Anadromous sea lamprey (Petromyzon marinus Linnaeus, 1758) uses many environments in its life cycle, which makes them even more susceptible to any environmental changes. Due to the potential of local ecological knowledge (LEK) in fishing villages on the Minho River, this study provided information on trophic chain, conservation, gastronomy, taboos, and food aversions of the sea lamprey. The discharge of pollutants, physical barriers, and climate change were considered a threat to the conservation of sea lamprey. Fishers’ LEK highlighted some preys from Osteichthyes and two potential predators (European otter and the Great Cormorant). Artisanal fishing was carried out predominantly at night and close to the village of Caminha, with the average of the largest sea lamprey caught was 2.6 kg. The price of this fishing resource could vary between 10 and 40 euros. Food taboos did not influence the conservation of this lamprey species. Local beliefs can assist in the promotion of eco-labels and greater recognition of local gastronomy. Alternative approaches to current scientific research can lead fishing villages that depend on these natural resources to contribute to the conservation of sea lamprey in the Minho river watershed.

当地生态知识对伊比利亚半岛海七鳃鳗（Petromyzon marinus Linnaeus，1758 年）的保护和可持续渔业的作用

摘要 溯河海七鳃鳗 (Petromyzon marinus Linnaeus, 1758) 在其生命周期中使用多种环境，这使得它们更容易受到任何环境变化的影响。由于 Minho 河上渔村的当地生态知识 (LEK) 的潜力，本研究提供了有关海七鳃鳗的营养链、保护、美食、禁忌和食物厌恶的信息。污染物的排放、物理障碍和气候变化被认为是对海七鳃鳗保护的威胁。Fishers 的 LEK 强调了一些来自 Osteichthyes 的猎物和两种潜在的捕食者（欧洲水獭和大鸬鹚）。手工捕鱼主要在夜间进行，靠近 Caminha 村，平均捕获的最大海七鳃鳗为 2.6 公斤。这种渔业资源的价格可能在 10 到 40 欧元之间。食物禁忌并未影响这种七鳃鳗物种的保护。当地信仰可以帮助推广生态标签和更好地认可当地美食。当前科学研究的替代方法可以引导依赖这些自然资源的渔村为保护米尼奥河流域的海七鳃鳗做出贡献。
