A study was conducted to investigation on the effects of probiotics on the biochemical parameters of Pangasius hypophthalmus fingerlings was conducted. Experiments were conducted in earthen ponds with P. hypophthalmus stocked at a density of 2.5 fingerlings/m2 and fed high-quality feed (28 crude protein) every day under biomass conditions. The experimental pond with Probiotics (E1) and control pond (C1) did not contain probiotics, and each treatment had six repetitions. Probiotics were supplemented with "Super PS" probiotics, which contain Rhodococcus and Rhodobacter. Periodically evaluated measures of water and soil quality revealed no stress and an acceptable range for fish growth. Following a 90-day culture period, E1 had the highest survival rate (98%) followed by C1 with 85.5%. The average weight of E1 was determined to be 500 g higher than that of C1, which differed considerably (p<0.001) from theirs (395 g). The food conversion ratio (FCR) in E1 was 1.58, whereas it was 2.18 in C1 and E1 produced a higher yield (4900.6 kg/0.4ha) than C1 (3377.2 kg/0.4ha). The study's conclusions showed that the E1 pond treated with "Super PS" had more growth, survival and yield than the C1 Pond.
