Fish is vacuum-pumped from the refrigerated sea water tanks (capacity 475m3), where temperature is kept between 2°C and -6°C, to the factory room which is equipped with machines for heading, gutting, skinning and filleting. Two production lines are arranged for the treatment of livers and roe, as they move from the processing area to be prepared, sterilised and packed in the canning factory. A Hetland fishmeal plant handles 150 tonnes of raw fish material daily to produce fishmeal and oil.
