Abstract

Abstract
According to many literatures marsh frog (Rana ridibunda) probably has the potential to become a commercial species which was exploited at least once about 30 years ago in Anzali wetland region.The global decline of amphibians urgently calls for a better understanding of amphibian population dynamics. Study of population size of marsh frog which has not been yet conducted in Gorigol wetland was carried out using the mark-recapture method. The objective of this study was to establish the population size of a population for contribution to the rather limited knowledge of the ecology of the species, which is widespread in Iran. We could not to achieve our main goal (i.e. estimating of population size) due to lack of enough recapture data. But, this study indicated that it is useful to conduct the robust design to increase the recapture probability of individuals. According to our results, a primary period needs to be one week, and within the week, the secondary periods should be the series of two nightly or more samples.
