Can you eat Greenlandic cod with a clean ‘green’ conscience? Yes you can, because thanks to modern gene tests, the authorities can reliably identify the cod populations that can be fished in a sustainable manner. DNA test helps Greenlandic cod A genetic test can be used to protect Greenlandic cod, and the method can also be used by the fishing industries in other countries. The test was developed at DTU. If you want to enjoy Greenlandic cod with a clean ‘green’ conscience, then it makes a difference whether you are munching on a fish that began life in a fjord or one that entered this world in the open sea. This is because although fish populations in the fjords have risen in recent years, the International Council for the Exploration of the Sea (ICES) still recommends that fishermen avoid fishing for cod that spawned in the sea as cod are still under threat here. The limitless sea Of course, the difficulty here is that the sea has no borders and the different cod populations sometimes swim in shoals, which makes it difficult to tell the difference between them. This is the case, for example, when it comes to cod fishing in the enormous fjord system around Nuuk. Until now, it has not been possible to determine definitively whether a given fish belongs to a vulnerable or a stable population, but using modern gene technology, a group of researchers from DTU Aqua has now come up with a solution to the problem.
