The objective of this study was to investigate the growth, survival rate of Sichon 1 strain
white shrimp during the Post Larva 13 - 40 stages, nursed with supplementary feed containing
Spirulina, Astaxanthin, and Yeast Protein.The experimental design followed a Completely
Randomized Design, with 4 treatment sets. Each treatment set included 3 replications. The
experimental groups consisted of : Treatment 1, providing commercial pellet feed (with 40 %
protein) as a control group; Treatment 2, providing commercial pellet feed (for early-stage shrimp
larvae) supplemented with Spirulina at a ratio of 10 grams per kilogram of feed; Treatment 3,
providing commercial pellet feed (for early-stage shrimp larvae) supplemented with Astaxanthin at
a ratio of 12 grams per kilogram of feed; and Treatment 4, providing commercial pellet feed (for
early-stage shrimp larvae) supplemented with Yeast Protein at a ratio of 10 grams per kilogram of
feed. Using Sichon 1 strain white shrimp with an average weight of 0.02 ? 0.00 grams and an
average body length of 0.64 ? 0.03 centimeters, totaling 14,400 individuals, the experiment
spanned 28 days (4 weeks). Results revealed that Experiment Set 3 exhibited the highest growth in
weight and length, with values of 0.78 ? 0.04 grams and 4.3 ? 0.25 centimeters, respectively. These
values were significantly higher than all other experimental sets (P<0.05). Experiment Sets 4, 2, and
1 showed growth in weight and length, with values of 0.60 ? 0.11 grams, 4.0 ? 0.30 centimeters,
0.45 ? 0.13 grams, 3.8 ? 0.33 centimeters, 0.37 ? 0.04 grams, and 3.6 ? 0.11 centimeters,
respectively. In terms of average survival rate, Experiment Set 1 had the highest rate at 92.28 ?
1.13 %. significant difference (P>0.05) between Experiment Sets 2, 4, and 3, with survival rates of
90.39 ? 7.11 %, 86.78 ? 5.33 %, and 83.05 ? 7.11 %, respectively. Regarding average daily growth
rate, Experiment Set 3 demonstrated the highest value at 0.03 ? 0.00 grams per day, significantly
differing from Sets 4, 2, and 1 (P>0.05), which had average daily growth rate values of 0.02 ? 0.00,
0.01 ? 0.00, and 0.01 ? 0.00 grams per day, respectively. Experiment Set 3 also exhibited the best
feed conversion rate at 1.14 ? 0.05, with no significant difference (P<0.05) from Sets 2, 4, and 1,
which had feed conversion rate values of 1.24 ? 0.11, 1.25 ? 0.11, and 1.26 ? 0.12, respectively.
Specific growth rate was highest in Experiment Set 3 at 9.57 ? 0.62 % per day, significantly differing
(P>0.05) from Sets 4, 2, and 1, with Specific growth rate values of 6.87 ? 1.23 %, 5.03 ? 0.59 %, and
5.01 ? 0.48 % per day, respectively
