Sardines and horse mackerel identified using forensic techniques
A team of researchers from Galicia in Spain have used forensic mitochondrial DNA species identification techniques to distinguish between sardines and horse mackerel. This method makes it possible to genetically differentiate between the fish, even if they are canned or processed, which makes it easier to monitor the degree to which fisheries resources are being exploited.
DNA from the mitochondria – cell organelles – is ideal for distinguishing between species. One of its components in particular, cytochrome b, is a genetic marker that scientists use to establish relationships ...
