KELANGSUNGAN HIDUP LARVA IKAN NILA YANG BERASAL DARI INDUK YANG DIBERI PAKAN BERIMUNOSTIMULAN
ABSTRACT: The objective of
this research was to evaluate the effect of feed supplemented with baker’s
yeast on survival rate of nile tilapia larvae and to determine the effective
dose of baker’s yeast that could optimally improve larval quality. The research was conducted at Pathology and
Clinic of Fish Disease from June – September 2014. Fish as brood stock candidates was cultivated
at five concrete tanks (2x1x1 m3) at a density of 30 fish per tank. Each tank was equipped with water inlet,
outlet and water pump for recirculating and aerating. After seven days of adaptation, fish was fed
pellet supplemented with baker’s yeast at five different doses (0, 10, 20, 30,
40 g/kg food) for four consecutive weeks at 4%/bb/day, twice daily. Larva was captured with seser and moved into
five glass aquaria with density of 20 larvae/aquarium and reared for two
weeks. Data collected was survival rate
of larvae achieved until the end of larval rearing. Research result showed that larvae produced
by brood stock fed food supplemented with 10 g baker’s yeast per kg food had
the highest survival rate namely 60%. As
conclusion, supplementation of baker’s yeast into brood stock feed might
increase survival rate of larvae.
