Abstract:RANA CATESBELANA (American Bullfrog). DIET. Data were obtained opportunistically
from 28 adult (M = 14; F = 14) bullftogs collected in April 2001 from the Meadow Valley Wash
located between the cities of Carp and Elgin, Lincoln County, Nevada, USA (N37'17':WI14'30'). Although there are two large summary reports on the bull frog that provide
publication lists of bullfrog food/diet literature (Bury and Whelan 1984. Ecology and
management of the bullfrog. USDI, FWS Resource Publ. 155. 23 pp.; Casper and Hendricks. In Press. Status and Conservation of U. S. Reptiles. M. Lannoo, Ed.), there are, to our knowledge, no published reports discussing bullfrog diets from this region. Sportsmen collected frogs using gigging techniques with the intention of removing the hind legs for consumption. After collection, frogs were assigned an identification number, weighed to the nearest gram, and measured from the tip of the snout to the vent (to the nearest millimeter). After the hind legs were removed by the sportsmen, the frogs were placed in plastic bags indicating the assigned specimen number and placed immediately on ice and transported to the laboratory. Stomachs were dissected and all contents placed in 10% formalin. As part of a related study, liver, brain, kidney, and muscle tissues were dissected and analyzed for mercury (Gerstenberger and Pearson. In Review. Mercury concentrations in bullfrogs (Rana catesbeiana) collected from a southern Nevada wetland. Bulletin of Environmental Contamination and Toxicology).
