| Abstract | ||
| The hatchability of eggs and the fecundity and survival of adult of Lymnaea auricularia snails was investigated in different pH and salinities. The current study showed that egg masses and hatchlings to be considerably more sensitive to salinity than the adult snails, while PH concentration unaffected on the hatching of eggs in all groups. The results revealed that L. auricularia snails remain alive in all concentrations and survival of these hatchlings was adversely affected by salinities as low as 0.5% and a salinity of 2.5 % was lethal within 10 weeks. In contrast, adult survival was has no effected in all concentrations of PH and all snails are survived up to 10 weeks. | ||
