Growth parameters in four populations of edible frog species in the Ouémé Valley (Republic Of Benin, West Africa)

Abstract

This study proposes to analyze the growth parameters of edible frogs in the Ouémé Valley in order to identify species of interest that may present considerable potential for the development of Beninese Raniculture. The methodology used consisted in sampling individuals of Hoplobatrachus occipitalis, Aubria subsigillata, Xenopus fishbergi and Xenopus tropicalis in the harvest of the frog catchers and making measurements on them, which made it possible to represent graphs of growth. At the end of the study, the results revealed that Hoplobatrachus occipitalis has an average weight and snout length of 93.8 ± 33 g and 117 ± 0.8 mm respectively. Aubria subsigillata has an average weight of 62 ± 18 g and a snout-length of 95 ± 0.9 mm and the genus Xenopus with an average weight of 24, 8 ± 23 g and a snout-length of 50 ± 0.13 mm. H. occipitalis and A. subsigillata appear through their seize performances like two species that can be recommended for raniculture.
