Perbedaan Suhu Inkubasi Terhadap Daya Tetas dan Lama Waktu Penetasan Telur Ikan Synodontis (Synodontis eupterus)

Abstract

This study aimed to analyze the effect of incubation temperature which different on hatching rate and hatching time of fish synodontis eggs (Synodontis eupterus), and to determine the optimum temperature for hatching rate and hatching time of fish synodontis eggs. This research is experimental research with parameters measured were the hatching time and hatching rate of synodontis eggs. The experiment using the Completely Randomized Design (CRD) method with 4 treatments difference, P1 (26-28°C), P2 (28±1°C), P3 (30±1°C), dan P4 (32±1°C) and 3 replications. The Results of this study show differences in the of incubation temperature significantly influence on hatching time of fish synodontis eggs (P<0.05), however not significantly influence on hatching rate of fish synodontis eggs (P>0.05). Hatching time obtained in treatment P4 (32±1°C) average value at 936 minutes (15 hours 36 minutes) and longest treatment P1 (26-28°C) average value at 1354 minutes (22 hours 34 minutes). Highest hatching rate of fish synodontis on treatment P2 (28±1°C) average value that was equal to 58,52% and treatment P4 (32±1°C) amounted to 34,61%. The Water quality parameter for research still considered viable to support hatching eggs fish synodontis
