Genetic Identification of Fish Species
Usually a fish species can be recognized by its morphology but very often commercial species are present in the market as steaks or as semi-finished foods (clean, pre-cooked, canned) making the identification difficult if not impossible. As an evidence of how this problem is real and actual, it’s that FDA requires DNA Barcoding analysis to be performed on every fish marketed in the US.
FEM2-Ambiente uses DNA barcoding methods to identify fish, molluscs, shellfish. The procedure starts with the extraction of DNA from few milligrams of product and then it involves the subsequent analysis using the most suitable DNA barcoding markers. Once the analysis is completed, a detailed certificate for each production batch will be issued indicating the kind of genetic analysis performed and the obtained taxonomic identification of the species.
Applications
- Certifying the genetic identity of a fish species
- Preventing frauds
- Checking the purity of a complex matrix
- Optimizing the production cycle
- Conveying a positive message to the market concerning the purity and quality of products.
Technical information
The genetic identification service analyzes the mitochondrial region COX-1 and eventually also other markers such as 16S rDNA region and Cyt-b gene. The DNA sequences obtained will be used to recognize the species of interest through their comparison with those present in inner and international databases (Fish Bold)
