<p>This research has a purpose to elucidate basic informations of the Rhinoclavis sinensis population dynamics at Krakal Beach, Yogyakarta, such as: (1) Studying the characteristics of population such as density, biomass, reproductive pattern, age, age structure, sex ratio, life span of R. sinensis temporarily from 2005 to 2008. (2) Studying the processes within population such as growth rate, reproductive pattern recruitment pattern, mortality (natural mortality and catch mortality) of R. sinensis. (3) Studying the respons of catching to the population of R. sinensis. The field research was basically collecting snails from residents every month, for the duration of four years from 2005 to 2008. Further the laboratory researches were including characterization of reproductive system such as the size of maturation, reproductive pattern based on gonad index, and age determination using operculum. Length frequency data were analized yearly and total four years using stock analysis such as: growth parameter (K, to, L&infin
