All heads of fish that are gutted on land are taken care of and hung on racks. This is a delicacy in many of the African countries.
Everything on the fish must be taken care of, and the same applies to the heads. After tongues and possibly cheeks have been cut out, the heads should be hung.
The heads are threaded on a long spike, and tied together into a fine strip. They are then transported out to the racks where they are hung in the same way as the stockfish, on their own racks. Here they hang for about 3 months.
The heads are then stacked in lorries and transported further out into the world. In recent years, there have been buyers in Lofoten who have bought the heads and arranged for sorting and further shipping to the wider world.
Heads are, as I said, a delicacy in some of the African countries, where Nigeria has excelled. In addition, in recent years, attempts have been made to use heads in, for example, protein powder. This is because 1000 kilos of cod heads can give up to 100 kilos of protein powder, and the protein content is as high as 80%!
