This current study aimed to investigate the effects of Vibrio harveyi induced Nodulisporium sp. KT29
administration on enhancement of bioactive compound concentration, surface of intestinal structure, and production
performance of Pacific white shrimp (Litopenaeus vannamei) cultured in the sea. The post larvae (PL) 10 of L.
vannamei was cultured at density of 1000 shrimp/m3
for 30 days in the sea. Completely randomized design was
arranged, consisting of 3 treatments with three replications, i.e C (control 0 mL/kg), NP (Nodulisporium sp. KT29
without induction of V. harveyi 20 mL/kg), NK (Nodulisporium sp. KT29 with induction of killed Vibrio harveyi 20
mL/kg), NL (Nodulisporium sp. KT29 without induction of living V. harveyi 20 mL/kg). The results revealed that
NK treatment showed the best effects on rising concentration of bioactive compounds, production performance, and
improving the density of shrimp intestinal structure compared to control
