Fingerprinting a fish

The DNASEEKER project developed simple DNA tests to prevent the mislabelling of fish, thus fighting fraud and ensuring the conservation of endangered fish stocks.

Dipstick test for tuna. The dipstick on the left is the control and shows a negative result. The extra red band on the other 3 dipsticks show a positive identification of the species.

This project, spearheaded by the Hellenic Centre for Marine Research and the University of Patra, developed rapid DNA dipstick tests to identify mislabelled fish species. These tests are designed to distinguish between similar species, such as sardines, anchovies, and tuna, which are frequently confused or deliberately substituted for more valuable varieties. The project also emphasised the creation of protocols and training materials for fish processing companies to ensure precise identification throughout the supply chain. This innovative approach addresses seafood fraud, supports consumer protection, and contributes to the global conservation of fish populations.

Results

  • Developed portable DNA-identification kits and mini-PCR devices for quick species identification.
  • Tested mini-PCR device (16 samples) with an electrophoresis unit for result analysis.
  • Devices enable immediate fish shipment control, reducing fraud and reliance on third-party labs.
  • Held training seminars for personnel on using the new DNA-analysis devices.
