| Research Abstract |
Growth initiates sexual maturation in fish. However, the onset of maturity leads to a marked loss of body weight. To avoid therisks associated with of spawning, yellowtail farmers have tried to restrict the dietfrom winter to spring, a period just before the breeding season. By restricting the diet they can avoid the reduction in body weight. In this study, we show how growth of fish is dependent on the control of diet by using endocrinological and physiological analysis of these cultured yellowtails.
