Abstract

This research. aims to determine the time of submersion of eggs, the betel leaf and the leaf extract of guava, against the hatchability of eggs and larva survival koi carp. (cprynus carpio L) this research carried on 28 september-26 oktober 2015 in an integrated laboratory university bunghatta.the method used in this research experiment method. research design that used in this research is completely randomized design . treatmente of A (control/without submersion) B(submersions with guava leave) C(submersion with betel leaf) and D( merger submersion betel leaf and guava leave). research shows that hatching eggs by submersions guava leave xtract significantly different and betel leaf, the level of hatching eggs were the highest in treatment B with a percentage of (91%).while that lowest in treatment A  with a percentage of (64.16%). of the average survivalof larva carp koi shows significantly different in treatment C  showed the average survival the highest (69.34%). and the lowes at treatment D (46.55%). thr highest growth the treatment of C (0.030gr). and the lowest in treatment B (0.023gr). while the highest absolute persentase long growht in treatment C (6.76 mm). and the lowest in treatment B (6.56 mm).
