A 120-day experiment was conducted to investigate the effect of different inland saline groundwater salinities on growth performance, nutrient utilization, physiological-metabolic responses, and haemato-biochemical indices of juvenile Labeo rohita. The experiment setup comprised 24 circular tanks, each of 400 L capacity with 250 L water volume, stocked with juvenile L. rohita (2.04 ± 0.01 g; n = 25). The experimental tanks were categorised
as seven treatments with different salinity levels viz., T1 (2‰), T2 (4‰), T3 (6‰), T4 (8‰), T5 (10‰), T6
(12‰), and T7 (14‰) and one control (0‰) with triplicates. No significant difference (p > 0.05) in growth
performance was observed with increasing salinity from control to T2, but the growth rate was found to be
suppressed significantly (p < 0.05) from T3 to T7. The highest and the lowest survival was recorded in control
(100%) and T7 (0%), respectively. Increasing salinity above T2 (4‰) significantly retarded growth and feed
utilization in L. rohita. Fish reared up to T2 (4‰) showed the highest amylase and protease activity, but those
reared in T3 to T7 displayed the decreasing trend of enzyme activities with an overall significant difference (p
