Abstract
The present study evaluated the effect of different probiotic applications, specifically water probiotics and soil probiotics, on the growth performance of Pangasius pangasius and the quality of water parameters during the culture period. The experiment aimed to determine the most effective probiotic treatment to enhance aquaculture productivity in an eco-friendly and sustainable manner. The experiment was conducted in four earthen ponds: a control group (C), T1 (MRS agar for Lactobacillus), T2 (TCBS agar for Vibrio spp.), and T3 (Tryptic Soy Agar) ponds, with varying compositions of soil and water probiotics. The results indicated that treatment T3 showed the best outcomes in terms of growth and survival of the experimental fishes. The mean average weight gain, Specific Growth Rate (SGR), and Feed Conversion Ratio (FCR) were also best in treatment T3, followed by T2, T1, and the control group. Based on these findings, it is concluded that while Tryptic Soy Agar (TSA) does not directly affect fish growth, it serves as a general-purpose microbiological growth medium used for cultivating a wide variety of bacteria and fungi. It provides a nutrient-rich environment for the cultured fish.
