Abstract
The Norwegian fishing fleet consists of different types of vessels, ranging from small boats to large factory trawlers. The fishing methods typically used in Norway are also described. Fishing vessels use different technologies and methods for keeping their catch cold and preserving fish quality and shelf life. Vessels may store the fish on ice, chill it in refrigerated fresh- and sea water, freeze the catch in plate freezers, brine freezers or use blast-freezers for single frozen fillets or deep-water shrimps.
Refrigeration systems contribute to greenhouse gas (GHG) emissions and, consequently, climate change. However, refrigeration is also necessary to avoid food losses, by keeping the fish quality more stable and increasing shelf life. Most Norwegian vessels have refrigeration or chilling of the fish as a standard practice, but many smaller vessels in other countries do not have that possibility.
This report covers description of fishing vessels, fishing methods and equipment for fish handling. It also describes different processing methods, including slaughtering, refrigeration, filleting etc. Energy saving methods are proposed and issues related to sustainability are described.
