PEMBERIAN PAKAN ALAMI YANG BERBEDA TERHADAP KELANGSUNGAN HIDUP DAN PERTUMBUHAN LARVA IKAN KOI (Cyprinus carpio)

Abstract

This research aims to understand the influence of the provision of feed natural different against survival rate and growth fish larvae Koi carp (Cyprinus carpio). This study was conducted in July-August 2015, in the laboratory integrated the faculty fisheries and of marine science university of Bung Hatta, Padang City. Method used in research this is the method his experiment with complete random design (CRD) with 3 treatment and 4 repetitions. Treatment A (fish larvae Koi carp given feed artemia non dekapsulasi) , treatment B (fish larvae Koi carp given feed artemia dekapsulasi) and treatment C (fish larvae Koi carp given feed Daphnia). The results of the analysis shows that the feed natural different in fish larvae Koi carp obtained survival highest is treatment A ( 92.9 %) and the lowest was in treatment C (90 %). The absolute is long highest treatment B (1.58 cm) , followed  treatment A (1.51 cm) while pesentase long growth absolute the lowest in treatment C (1.37 cm). The absolute is heavy highest treatment B (0.29 gr) , followed  treatment A (0.28 gr) and lowest in treatment C (0.17 gr).
