The Ability of Some Snails (B. alexandrina, M. tuberculate, and P. acuta) for Growth and Reproduction in Artificial Environment

Three different species of Snails, B. Alexandria, M. tuberculata and P. acuta are selected from lake Tauorgha. Libya. The results show that physa acute is more adaptive for life in captivity when Kept in aquaria for period of time from three months to one year. M. tuberculata snails are able to reproduce but with a loss degree than P. acuta, when water from lake Tauorgha. Also, tap water is added to the aquuria, P. acute continued to live in the artificial environment for less than three months. P. acute snails are the most resistant to the artificial conditions with more observable reproductive ability while M. tuberculata has less ability that of P. acute but B. alexandrina survived those artificial enrironment condition for few days. The present study revealed that of (720) B. alexandria snails (720) with a different shell size (15.13%) were found naturally infected with Fasciola (cercaria) and S. mansoni (cercaria) (p 0.01).
