Abstract | ||||
Fifteen snail species related to classes Pulmonata and Prosobranchia have been collected from five different localities in Behera province. Pulmonata snails rep < /strong>resented by Biomphilaria alexandrina, Bulinus contortus, Bulinus dybowski, Bulinus innesi, Planorbis philippi, Physa acuta, Lymnaea caillaudi, Lymanaea alexandrina and Helisoma duryi. Prosobranchia snails represented by Cleop < /em>atra bulimoides, Cleopatra - cyclostomoides, Melania tuberculata, Vivipara unicolor, Neritina nilotica and Lanistes boltini have been collected. Seasonal incidences of snails were high in spring followed by autumn and winter while decreased in summer. Factors affecting snails p < /strong>opulation were also studied (under field conditions), including water temperature, light, water depth and hydrogen ions concentration (PH). | ||||
