The correct labeling of seafood is important to protect nature and the rights of consumers. Given the certainty that the resources of the sea are not inexhaustible, only strict regulations and the implementation of sustainable fishing systems and reliable and traceable marketing systems can help ensure the long‐term sustainability of fishery resources. Detecting mislabeling and seafood fraud is a useful resource for improving students' motivation and developing active learning methodologies in higher education. In the present study, we have proposed to the students a lab exercise consisting of exploring 25 different commercial cephalopod products from three major European supermarkets by using DNA barcoding and analyzing the results under the framework of EU and Spanish regulations. The problem is connected with the last theme (traceability) of the Conservation Genetics and Breeding course with the aim of providing students with a practical research lab experience about a real problem before going deeper into more theoretical contents. In this way, they can use the knowledge and the skills they acquired previously to better comprehend and think critically about the problem. Findings from students' answers to a survey revealed that the use of this approach generates useful information for communities, increases curiosity and feelings of benefit, and leads to high levels of satisfaction with lab practices compared with those in other courses. In conclusion, lab exercises focused on seafood control, in addition to being viable, can be used as a tool in classes to improve students' commitment to higher education.

本科阶段海鲜控制的实验室经验：以头足类动物为例

海产品的正确标签对于保护自然和消费者的权利很重要。鉴于海洋资源并非取之不尽的确定性，只有严格的法规和可持续捕捞系统的实施以及可靠和可追溯的营销系统才能帮助确保渔业资源的长期可持续性。检测贴错标签和海鲜欺诈是提高学生积极性和发展高等教育主动学习方法的有用资源。在本研究中，我们向学生提出了一项实验室练习，该练习包括通过使用 DNA 条形码探索来自欧洲三大超市的 25 种不同商业头足类产品，并在欧盟和西班牙法规的框架下分析结果。该问题与保护遗传学和育种课程的最后一个主题（可追溯性）相关，旨在为学生提供有关实际问题的实践研究实验室经验，然后再深入研究更多理论内容。通过这种方式，他们可以利用之前获得的知识和技能来更好地理解和批判性地思考问题。学生对调查的回答表明，与其他课程相比，使用这种方法可以为社区提供有用的信息，增加好奇心和受益感，并导致对实验室实践的高度满意。总之，专注于海鲜控制的实验室练习，除了可行之外，还可以用作课堂工具，以提高学生对高等教育的承诺。
