The the end of a fish day, fishermen take their fish to a cannery, or fish processor. The processor buys the fish from the fishermen. The fish price depends upon many factors such as how many fish are being caught, and how many fish the processors think they can sell. Fish processors use many machines to process fish.
Some machines dehead the fish, others gut the fish, and still others pack the fish in boxes.
Fish eggs are carefully collected during the processing. Fish Technicians first wash the eggs and then salt and dry them to preserve them. They are sold in Japan as expensive Salmon Roe. Many people work at fish processors during the fishing season. Workers must be at least 16 years old to work at a processor.
