  It takes quite a long time for the grouper to spawn. In the case of red spotted grouper (Epinephelus akaara), at least three to four years of rearing is usually required to reproduce them for the first time. Reproductive control techniques can be applied to repress, delay or advance the onset of puberty. Thus, they can be used to accelerate the process of selective breeding in this species. The present study investigated whether alterations of rearing water temperature (WT) can advance the onset of puberty in the red spotted grouper. Juvenile red spotted grouper (110 DAH, 7.25 ± 0.5 cm, 6.45 ± 1.5 g) were randomly divided into 4 groups and reared for approximately 10 months (from Nov. 2014 to Aug. 2015) at four different WT: natural condition (12.6-19.5°C), 20 ± 0.5°C, 24 ± 0.5°C and 28 ± 0.5°C treatment. When they were reared at 24 &.. View More»
