Stockfish are widely cultivated in Norwaydue to their suitable cool-dry weather conditions proven to be the perfect weather for the drying, preservation and probably for exportation of Codfish to other countries of the world. Cod/Stockfish are usually cleaned and dressed immediately after they are captured and beheaded; they are dried as a whole, divided into halves or by just removal of the heads from the body.

The fish are normally tied to wooden racks or sticks from February-May in an open dry air, after which they are brought indoors for another 2-3 months in a well-ventilated and dry location for them to get dried and matured.

The dry wind of the month of February- May with the cool temperature of 0oc are often found favourable for protecting the fish from insectsand prevents the growth of bacteria. Drying is often seen as the best method of preserving cod/stockfish, it helps the fish to stay for a longer period of time. The process by which the fish are dried is known as”hjell” inNorway. Codfish can last for several years after preservation for easy delivery to consumers all over the world.

Codfish (Stockfish) are usually air or wind dried by fishermen on wooden racks in Norway before importing them to other places in the world. The drying process allows Cod to loss about 70- 80% of their moisture with the exception of all other nutrients.

After the purchased of either fresh or dried codfish, you have to keep maintaining the quality and the freshness depending on the time you want to make use of it by storing it in the coolest part of the refrigerator, for the dried codfish, they can be sun dried in a wired basket with lid to prevent maggots and other insects from ruining them. The wired baskets can also be tied close to local fire place for places that have continuous rainfall or high humidity, this is to prolong the quality of the fish and to enable them stay for a longer time.

Selection process ofcod/stock fish

After Cod fish are dried, they are further sorted out into various grades of quality based on their lengths, thickness and weights. The sorting is carried out as laid down standards that have been around for ages in Norway. The three categories at which Cod fish are sorted into include:

  • First class (Prima)
  • Second class (Sekunda)
  • African quality which is the third class (Tipo B), after which they are packed in hessian wrapped to enable fresh air pass through, to further dry the fish. The bales are usually from 45-50kg net.

Codfish or Stock fish are usually mistaken to be clipfish or salted cod, another type of cod which are usually soaked in salt water for 2-3 weeks to salt mature before drying in the sun or an open air.
