The raw material is of great importance, both in terms of catch damage, guidance methods and storage before hanging. The actual drying of slabs is the second important factor in achieving the quality of the end product. In 2008, a preliminary project on stockfish on shells was carried out ( FHF-900003 : Mapping of factors that affect the drying of fish on shells: Preliminary project) which looked at which factors had an impact on stockfish quality, while the fish hang on shells. Humidity and temperature measurements were performed in both air and fish. The knowledge of what affects the quality while the fish is hanging on a rock was also tried to be systematized by talking to players in the industry. The results from the preliminary project showed in short that the fish are exposed to high or low temperatures for relatively short periods, which probably affects the quality negatively. Especially direct solar radiation on the fish will be able to raise the temperature in the core of the fish to almost 20 degrees above the air temperature. Higher humidity was also measured inside large rock areas, which is probably due to poorer drafts. Considering that one in the stockfish industry wants to continue drying outdoors in much the same way as before, some measures emerged that can provide better quality of the stockfish on the shelf, without removing natural outdoor drying. Some of the proposals go on permanent arrangements, such as placement of cliffs, height of cliffs, design of cliffs, fish hanging direction, and hanging density. Other proposals include short-term measures such as spraying water on the fish when it is sunny, covering the fish in the sun, cold and prolonged rain and using fans to get draft when it is quiet
