Table 1

Effect on fecundity, hatchability, and survivability of snails kept for 8 h exposure in different visible spectrum of light.

	24 h	48 h	72 h	96 h		24 h	48 h	72 h
Control (no light)	250 ± 0.2	197 ± 0.9	102 ± 0.7	50 ± 0.40	34 ± 0.63; (10–12)	45 ± 1.8	25 ± 1.6	12 ± 0.96
Red light	89.3 ± 0.4	63.2 ± 0.2	20.3 ± 0.8	0	32.6 ± 0.91^+; (14–17)	22 ± 0.9	13 ± 0.01	0

Each experiment was repeated six times and the values of fecundity, hatchability, and survival were the mean of six replicates. Significant () difference was noted when Student’s -test was applied to treated and control groups.
⁺Product moment correlation coefficient showed that there was significant () negative correlation in between exposure period and fecundity of L. acuminata snail. (0) shows no fecundity, hatchability, and survival.
