Comparative Study On Reproductive Behavior Of Three Thai Indigenous Apple Snails Pila Celebensis (Quoy & Gaimard, 1834), P. Pesmei (Morlet, 1889) และ P. Virescens (Deshayes, 1824), Supunya Annate
Chulalongkorn University Theses and Dissertations (Chula ETD)
Species of the Thai indigenous apple snail genus Pila Röding, 1798 are undergoing population decline. Accordingly, their conservation is needed, but the lack of knowledge of their reproductive biology is a significant obstacle to implementing conservation measures. Therefore, this study analyzed the mating and egg-laying behavior of three of the five Thai indigenous apple snails: P. celebensis, P. pesmei, and P. virescens using continuous video recording under laboratory conditions. In addition, the egg-laying behavior of P. virescens in a seminatural habitat was observed in the rainy season of 2023. Moreover, their egg, egg mass, incubation time, and hatchling characteristics were …
