Crawfish frogs Lithobates areolatus inhabit the tallgrass prairie of the southeastern Great Plains and Mississippi Delta, and have recently been considered for US federal listing under the Endangered Species Act. Here we attempt to determine the feasibility of head-starting rawfish frog tadpoles, and establish captive-rearing protocols. Captive-rearing produced more juveniles from fewer egg masses than a natural wetland in each year from 2013-2015, and urvivorship of captive-reared tadpoles exceeded that of wild tadpoles. However, high rates of malformations, partial cannibalism, disease, and predation were seen among frogs in some years, and we therefore refined protocols to reduce these issues.
