Abstract: The of effect of L-ascorbic acid as a source of vitamin C was assessed on the egg hatching performance and spawn survival of blue gourami, Trichopodus trichopterus. The eggs were procured from nests and immersed in L-ascorbic acid at the concentrations of 250 mg L-1 (T1), 500 mg L-1 (T2), 1000 mg L-1 (T3) and 2000 (T4) mg L-1 with control (T0) in the experiment. Egg incubation period was ranged from 18 to 21 h with 100% hatching rate. The eggs were hatched out after 18 h in the treatment T3, followed by T2 (19 h), T1 and T0 (20 h) and T4 (21 h). The maximum survival (97.5%) of spawn was recorded in T3 and the minimum in T4 (62.5%) after 20 days of spawn rearing. Results showed that a treatment of 1000 mg L-1 L–ascorbic acid decreased egg incubation time and significantly better (P<0.05) survival of spawn.
