Fish can be bought everywhere. If you want to buy fresh fish you have to pay attention to the freshness of the fish and that the fish doesn’t have a strong smell. The fish fillets must be firm and the colour must be slightly transparent. If you want to be sure your fish is fresh, you can buy fresh frozen fish. The fish are frozen directly after being caught from the water. You can buy fresh frozen fish at the supermarket. During the process of freezing all nutrients, as vitamins and minerals, are being kept. Fresh frozen fish is therefore a healthy choice.
