The fish industry contributes to the nation’s economy annually representing 4.5 % of the Gross Domestic Product (GDP) and twelve (12) % contributions to agriculture. There are several fish processing methods in Ghana such as smoking, salting, frying, sun-drying, freezing, and fermentation. Smoking is one of the common ways of preserving fish in large quantities. Wet hot smoking and dry hot smoking are the two forms of fish smoking which consist of three stages of smoking fish namely; cooking stage, drying stage and smoking stage. Predominately, the fish smoking industry is mainly dominated by women and young girls. Fish processing activities are done around and along the coastal waters and river banks. The technologies used in fish smoking in Ghana are improved types of conventional fish smoking ovens, chorkor smokers, oil drums and acceptance of upgraded smoking techniques. Usually, the fish species smoked are catfish, herring, mackerel, anchovy, and tuna. The smoked fish are stored in empty baskets line with brown papers and as well covered with brown papers.
