| Outline of Final Research Achievements |
To establish the efficient fish culture, I analyzed the relationship between growth and maturation of several fish in endocrinologically. As a result of the analysis using several fish species, the gonads are necessary for normal growth and thus, from the perspective of regulation of body growth, can be considered a “secondary pituitary”, and it is considered that the role of gonad for body growth is the production and secretion of growth hormone and/or estradiol-17 beta (E2). Furthermore, I detected the relationships between maturation and environmental condition (water current), and maturation and nutritional factor. These finding is fundamental knowledge for regulation of maturation for the establishment of the efficient fish culture.
