Start year 2011 End year 2011 Funding (€) € 125,748 Website https://www.fhf.no/prosjekter/prosjektbasen/900598/ Summary The projects that have been carried out on stockfish in recent years, “Mapping of factors that affect the drying of fish on shells: Preliminary project” ( FHF-900003 ), “Controlled drying of stockfish” ( FHF-900194 ) and “Controlled drying of stockfish: Large-scale test with net over the stockfish ”( FHF-900438 ) has provided significant insight into how the sun affects the temperature in the fish and how it in turn affects the quality. In the present project large-scale experiments have been carried out with hanging stockfish under shade nets. The fish were hung at three times on March 1, March 23 and April 14. At each of the times, fish were also hung as a control, without a net. The use of a shadow net over stockfish while hanging on a reel reduces the temperature of the fish both measured as an average throughout the season and the effect is especially great on sunny days. Although this temperature effect is present, the results show that the quality is unchanged for some quality defects, while the quality is deteriorated for other quality defects. No quality improvement has been found on any important and typical quality defects in stockfish. The tested 70% shade net therefore has no intention of improving the quality of stockfish. The work documents that traditional outdoor drying that is practiced in the industry, gives better quality of the stockfish than when using protection with a shade net. The experiments were carried out at Brødrene Berg AS, Værøy.
