How the raw material for stockfish production is stored before drying has been said to effect the stockfish quality. This was investigated in trails carried out at 3 different stockfish producers in Lofoten. The raw material was followed from catch to dried stockfish and rehydrated stockfish. Fresh cod caught with longline, gillnets and line was stored in 4 different ways for approximately 24 hours; gutted or whole in seawater or in a dry container.
The results showed that storage of gutted fish in seawater gave the worst stockfish quality while the best way to store the raw material was whole fish in a dry tank or in seawater. This was the result for total quality (amount of prima fish), for degree of mucoso and for amount of fish infected with worms from flies. The results were the same for all 3 types of fishing gear. For the fishing boats these results indicate that the raw material must not be carried gutted in seawater for long periods. For the stockfish producers the results implies that the fish should not be stored in seawater overnight before being hanged to dry.
