Abstract
This study evaluated the physiological effects of integrating Jeevamruth (a traditional microbial consortium) and millet-based biofloc technology on Labeo rohita. The experiment utilized a Completely Randomized Design (CRD) with five treatments: Control (C), Biofloc (T1), 0.5% Jeevamruth (T2), 1% Jeevamruth (T3), and Biofloc + 0.5% Jeevamruth (T4). A total of 45 fish (n=3 per tank) were sampled for Organosomatic analysis after a 60-day culture period. Results indicated that the Hepatosomatic Index (HSI) remained stable across all treatments (p > 0.05), ranging from 1.19% to 1.62%, demonstrating that the organic amendments did not induce hepatic stress or toxicity. Conversely, the Intestinosomatic Index (ISI) showed significant variation (p < 0.05), with the lowest value recorded in T4 (6.29 ± 0.37%) compared to the Control (9.57 ± 0.07%). This reduction in intestinal mass suggests enhanced nutrient assimilation and digestive efficiency driven by the synergistic microbial environment. The study concludes that combining Jeevamruth with biofloc creates a bio-secure, nutrient-rich rearing system that supports optimal physiological health in Labeo rohita, validating its potential for sustainable, low-input aquaculture.
