Peningkatan Pertumbuhan Ikan Nila (Oreochromis niloticus) Melalui Pemberian Immunostimulan Ragi Roti (Saccharomyces cereviciae)
Abstract: This research aimed
to examine the effect of baker’s yeast as immunostimulant on growth of nile
tilapia and to find out a proper dose of baker’s yeast that promoted optimal
growth of fish. Juveniles with an average weight of 31.83 g were obtained from
stock available at Aquaculture Study Program of the Faculty of Fisheries and
Marine Sciences. This research was conducted at the experimental ponds located
at the Faculty of Fisheries and Marine Sciences for three months. During the
experiment, fish was fed with pellet supplemented with baker’s yeast as treatment
for four weeks as much as 4%/bw/day, twice daily. The doses of baker’s yeast consisted
of 0, 10, 20, 30, and 40 g/kg pellet. Fish growth including absolute and
relative growth was measured at two weeks interval. Research results showed
that after two weeks of feeding, supplementation of baker’s yeast did not
affect the growth of fish but after four weeks of feeding, supplementation of
baker’s yeast significantly increased fish growth. Fish fed pellet supplemented
with 10 g baker’s yeast displayed the highest growth. As conclusion, supplementation of baker’s
yeast in fish food could enchance the growth of fish.
