Abstract

Synodontis eupterus is one of the ornamental fish that have high economic value, because of its unique behavior which could swim in reversed position. It is necessary to gather biological information to support the necessary process of domestication and cultivation. Research on Synodontis eupterus still rarely performed. One of the necessary data informations is the optimal temperature for the cultivations of Synodontis eupterus. The purpose of this study was to determine whether there are differences in the effect of incubation temperature on hatching time and hatching time of Synodontis eupterus eggs, and to know the optimal temperature for the hatching time and the hatching rate of Synodontis eupterus eggs. The research was conducted from April to May 2016 in the Central Research and Development of Ornamental Fish Farming Depok, West Java. The method used in this research was the experimental method, which was experimenting with the treatment of eggs differences temperature incubation. The main parameters measured were the hatching time and hatching rate of Synodontis eupterus eggs. This experiment used completely randomized design with 4 treatment temperature difference, A (25-26oC), B (28-29oC), C (31-32oC) and D (control), with 3 replications. The results showed that the fastest hatching time of Synodontis eupterus obtained in treatment C at 1120 minutes (18 hours 40 minutes), then treatment B at 1240 minutes (20 hours 40 minutes), then treatment D at 1340 minutes (22 hours 20 minutes) and longest hatching time in treatment A at 1760 minutes (29 hours 20 minutes). Highest hatching rate of Synodontis eupterus obtained in A treatment that was equal to 94.67%, then C treatment that was equal to 82.67%, and treatment D amounted to 81.33% and lowest hatching rate in treatment B 80.00%. Based on the results of the study showed that the optimal temperature to accelerate the Synodontis eupterus for hatching time was at a temperature of 31-32oC. Keywords: Hatching Eggs, Hatching Time, Incubation Temperature, Synodontis eupterus.
