Morphology of Female Tilapia (Oreochromis sp.) Broodstock at Hatchery Centers in South Sulawesi

Abstract

This study aimed to evaluate the morphology of female tilapia (Oreochromis sp.) broodstock used in 3 hatcheries in South Sulawesi. A total of 92 female tilapia broodstock were collected from 3 hatcheries in South Sulawesi: Gowa Regency (30 fish), Bantaeng (30 fish), and Soppeng (32 fish). Morphological measurements were taken using a ruler on eight characters including the TL, SL, HL, SnL, CPL, BH, CPH and HH. Comparison of values among morphometric characters SL, HL, SnL, CPL, BH, CPH, and HH to TL was analyzed for variance (Anova) and continued with Duncan’s comparison test. The results of the analysis showed that the SL/TL characters were not significantly different (P > 0.05) between hatchery locations, while the HL/TL, SnL/TL, CPL/TL, BH/TL, CPH/TL, and HH/TL characters were significantly different (P < 0.05) between locations. Most of the morphological characters in female broodstock originating from Gowa and Soppeng contributed greatly to the formation of the first main axis (F1), while the rest were scattered on the second (F2) and third (F3) axes These results indicate that, in general, in terms of morphometric variations, the female broodstock at the three tilapia hatcheries have different morphometric characteristics.
