"All three species of Seriola, greater amberjack, Japanese amberjack and yellowtail amberjack, have good market demand, mainly in Japan...The main cultured species is Japanese amberjack (S. quinqueradiata)...Since the 1980s, Japanese yellowtail farmers have had a difficult time with increasing production costs due to the rising costs of feed (caused by a drastic decline in the volume of sardines caught in Japanese waters), a poor supply of juvenile Japanese amberjack ("mojako"), and the stagnant Japanese economy... Generally, a 20 g "mojako" reaches 3.5 kg (the average market size) in around 2 years." JapanMore info.Capture-based aquaculture
