The Japanese amberjack or yellowtail, Seriola quinqueradiata, is a species of jack fish in the family Carangidae. It is native to the northwest Pacific Ocean, ranging from China (called 鰤鱼), Korea (called 방어), and Japan to Hawaii. Some of the fish consumed are caught wild, but a substantial amount is farmed (about 120,000 tonnes per year). To populate the pens, every May, workers fish for the small wild fry (called mojako), which can be found under floating seaweed. They scoop out the seaweed together with the mojako and put the mojako in cages in the sea. * Juvenile Japanese amberjack * *
