The present study investigated the effects of exposure to different light spectra and intensities on ovarian maturation in yellowtail damselfish, Chrysiptera parasema over a 4-months period. We used a white fluorescent bulb and three different light-emitting diodes (LEDs: red, peak at 630nm; green, 530nm; blue, 450nm), at three different intensities each (0.3, 0.6, and 0.9W/m(2)). The effects of different illuminations were assessed by measuring the mRNA and protein expressions of vitellogenin (VTG) and estrogen receptor (ER), gonadosomatic index (GSI), and plasma estradiol-17β (E2) hormone level...
