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 (T
1), 500 mg L
-1 (T
2), 1000 mg L
-1 (T
3) and 2000 (T
4) mg L
-1 with control (T
0) 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 T
3, followed by T
2 (19 h), T
1 and T
0 (20 h) and T
4 (21 h). The maximum survival (97.5%) of spawn was recorded in T
3 and the minimum in T
4 (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.
