PEMANFAATAN RAGI (SACCHAROMYCES CEREVISIAE) PADA FORMULASI PAKAN DALAM MENINGKATKAN PERTUMBUHAN IKAN NILA (OREOCHROMIS NILOTICUS)
ABSTRACT: The purpose of this
research was to determine the effect of yeast (Saccharomyces cerevisiae) with
different composition of 5%, 10%, 15%, 20%, and without yeast in feed
formulation on growth of tilapia (Oreochromis niloticus). The experimental fish
used in this study had an average lengths of 2-3 cm and weight of 1.0 g. This research used cage measuring 100 x 100 x
100 cm3 that was placed in outdoor concrete pond of 3.5 x 5 m2. Each cage filled with 10 fishes with three
replication. The dose given to the fish
was 10% of the weight of biomass. The
fish was fed for three weeks, 3 times a day at 08.00 am, 12.00 pm, and 16.00
pm.. Research results showed that the greatest growth was achieved in fish
treated 20% yeast and the lowest was observed in control fish (without yeast).
Based on statistical analysis, all treatment displayed similar effect on all
growth parameters.
