Figure 4From: Increased expression of kisspeptin and GnRH forms in the brain of scombroid fish during final ovarian maturation and ovulationChanges in peptide levels of GnRH1 (A), GnRH2 (B), and GnRH3 (C) in the brain of adult chub mackerel during different stages of spawning cycle. Each bar represents mean ± SEM from 4–6 fish per ovarian stage (Refer Table 1). Different letters above the bars represent significant differences (p<0.05) between stages. LV, late vitellogenesis; GVM, germinal vesicle migration; HY, hydration; OV, ovulation; POV, post-ovulation.Back to article page
