Abstract:
Feed is a very important factor in vaname shrimp
aquaculture. The addition of phytoecdysteroid supplements
(vitomolts) to the feed can increase protein retention, thus the
shrimp growth will be better. This study aimed to determine the
appropriate dose of Vitomolt supplement in feed for growth and
survival of vaname shrimp seeds. The results of this study are
expected to be useful in determining the best Vitomolt
supplementation in the vaname shrimp feed formulation. The
experimental animal used was the vaname shrimp seeds with an
average initial weight of 1.5 g per individual. The research design
used was a completely randomized design (CRD) with 4
treatments, namely treatment A without Vitomolt supplement, B
1.5 g Vitomolt /kg feed, C 3.0 g Vitomolt/kg feed, and D 4.5 g
Vitomolt /kg feed. Each treatment had 3 replications, hence there
were 12 experimental units. The experimental feed application
was carried out for 40 days of maintenance. The results showed
that the treatment of Vitomolt supplement dosage in the feed had
a significant effect on the daily growth rate and survival rate of
vannamei shrimp. The results of further tests showed that the
vitomolt dose of 4.5 g/kg of feed was significantly different from
the treatment without vitomolt, but did not differ from those with
1.5 g and 3.0 g /kg of feed Vitomolt dose on the daily growth rate
of vaname shrimp seeds. Furthermore, the Vitomolt dose of 3.0 g
/kg of feed was significantly different from the treatment without
Vitomolt but not significantly different from 1.5 g and 4.5 g /kg of
feed Vitomolt dose, on the survival rate of the vaname shrimp
seeds. Based on the results of this study, it is recommended to add
3.0 g /kg of vitomolt for vaname seeds feed.
