Herring stone is obtained by processing herring. After processing, the water and other components of herring will be reduced, thus obtaining herring stone. Therefore, the weight of 16 kg herring after processing will be lighter than the original herring.

The weight of herring stone depends on the water content and processing method of herring. The weight of herring stone will be reduced by about 30% to 50% compared with the original herring. So 16 kg of herring can get 8 to 1 1 kg of herring stone.
