Lab experience with seafood control at the undergraduate level: Cephalopods as a case study

Area of Science:

• Marine Biology
• Food Science
• Educational Methods

Background:

• Accurate seafood labeling is crucial for consumer rights and marine resource sustainability.
• Seafood fraud and mislabeling pose significant challenges to conservation efforts and market integrity.
• Sustainable fishing and traceable marketing systems are essential for long-term fishery resource management.

Purpose of the Study:

• To implement a DNA barcoding lab exercise for university students to investigate seafood mislabeling.
• To connect theoretical concepts of traceability with practical research experience in conservation genetics.
• To assess the impact of this hands-on approach on student motivation, learning, and satisfaction.

Main Methods:

• Analysis of 25 commercial cephalopod products from major European supermarkets.
• Application of DNA barcoding techniques for species identification.
• Evaluation of findings within the context of European Union and Spanish regulations.

Main Results:

• The DNA barcoding approach successfully identified mislabeled seafood products.
• Student surveys indicated increased curiosity, perceived benefits, and high satisfaction with the lab exercise.
• The practical experience enhanced students' comprehension and critical thinking regarding seafood traceability.

Conclusions:

• Lab exercises focused on seafood control are effective and viable educational tools.
• This methodology can significantly improve student commitment and engagement in higher education.
• Practical application of genetic techniques aids in understanding real-world conservation and consumer protection issues.
