ABSTRACT
The protein utilization in feed significantly contributes to the preservation and bolstering
of the sustainability of aquaculture endeavors. This study uses a zero-water exchange system to evaluate
the effects of three commercial feeds with varying protein content on the nursery of Pangasionodon
hypopthalmus. The research employed fish with an initial size of 11.54 ± 0.04 g, which were reared
for 84 days using a closed system pond. The experimental treatments in this study encompass
feeds containing protein contents of 20% (F20), 25% (F25), and 30% (F30). Findings revealed that
the F30 treatment yielded the best production performance, with a specific growth rate and survival
rate measuring 2.81 ± 0.08% day-1 and 99.83 ± 0.29%, respectively. Additionally, utilizing F30 resulted
in the lowest Feed Conversion Ratio (FCR) at 1.75 ± 0.11. Employing lower protein content in the feed
led to improved water quality. Nevertheless, employing F30 feed still maintained water quality within
the acceptable standards for the P. hypophthalmus juvenile cultivation.
