The diagram illustrates the process of preparing fish from the moment it is caught at sea to when it is sold at a fish shop.
Overall, the process involves a series of stages beginning with fishing at sea and ending with the distribution of fish to shops. The fish undergoes several treatments including freezing, cutting, soaking, and smoking before being delivered for sale.
First, fish are caught in nets at sea and then transferred to a fishing boat. After that, they are brought to the port and frozen immediately to preserve freshness. Later, the frozen fish are thawed and cleaned using fresh water.
Next, the fish are cut open to remove the internal parts and soaked in salt water mixed with yellow coloring. Following this, they are smoked for flavor and preservation.
After the smoking process, the fish are frozen again at 0°C and placed into cold storage. Finally, they are transported by truck and distributed to fish shops for sale.
