Morphoanatomical indexes of female Siamese fighting fish Betta splendens under different photoperiod regimes
2025
Overview
Photoperiod represents light manipulation to advance or delay reproduction in Siamese fighting fish (Betta splendens Regan, 1910). This study aimed to evaluate different photoperiod regimes against ovarian maturity of fish by examining morphoanatomical indexes. The female Siamese fighting fish underwent different photoperiod regimes, for 45 days, i.e. P1 (10h light, 14h dark), P2 (14h light, 10h dark), and P3 (ambient light as control). Morphoanatomical indexes were accessed through gonadosomatic index (GSI), hepatosomatic index (HSI), and viscerosomatic index (VSI), being corelated With vitellogenesis. Vitellogenesis was analyzed through ovarian histology preparations. Results showed that GSI, HSI, and VSI were statistically significantly different in P2 (38.25%, 24.61%, 34.93%). P1 (25.48%, 18.23%, 22.53%) and P3 (15.92%, 12.55%, 15.71%) were not different. These photoperiod regimes affected female morphoanatomical indexes. GSI, HSI, and VSI increased comparably with vitellogenesis. HSI and VSI promoted GSI at a high-level.
