Abstract
Photoperiods is one of the factors that influence regulation on endocrine gland in producing hormones necessary for gonadal growth and development, gametogenesis and reproductive cycles in fish reproduction. This study clones the gonadotropin hormones I (GtH-I) and II (GtH-II) genes in hard-lipped bard, and investigates the effect of photoperiod on the genes expression. Experiment was designed using three treatments; 14L: 10D (control), 8L: 16D (short photoperiods), and 18L: 6D (long photoperiods). Four aquariums with nine fish/tank were used, serving as replicates. Fish were kept under this photoperiods treatment for eight weeks. Pituitary activities were obser...
