Abstract:This study used one-year-old red spotted grouper Epinephelus akaara as target species, aimed to investigate the growth and gonadal development of this species exposed to white (3000 K), red (590 nm), blue (480 nm), and green (520 nm) light emitting diodes (LEDs) for two months. The growth and gonadal development were compared. The gene expression of growth-related hormones such as PSS-Ⅰ, NPY and GH, and reproduction-related hormones such as Kiss1, Kiss2, GPR54, sbGnRH, FSHβ, and LHβ in the brain and pituitary was analyzed using qRT-PCR technology. The results showed that at the end of the experiment, the total length of fish in white group was significantly higher than that in blue and green groups (P<0.05), and the body weight was significantly higher than that in green group (P<0.05). There was no significant difference in GH gene level (P>0.05), contrarily, the PSS-Ⅰ gene level was significantly higher than that at the begining of the experiment, suggesting limited effects of PSS-Ⅰ on inhibition of GH synthesis. The significantly increased NPY gene levels in four light groups (P<0.05) indicated that four light quality were effective to stimulate food intake. After two months, the gonad developed from chromatin nucleolar-stage oocytes to perinucleolar-stage oocytes in four light groups. The GPR54 levels in four light groups and sbGnRH levels in white and blue groups were significantly increased when compared to the begining (P<0.05), without significant differences in FSHβ and LHβ gene expression in the four light groups, suggesting that the two genes may not play important roles on the development of reproductive system in the one-year-old red spotted grouper. In summary, the white light was more effective to accelerate the growth of the experimental fish, and may not induce the gonadal development.
