Abstract
The bullfrog was introduced to Japan in 1918 to be farmed for human consumption. Japan began to export
bullfrogs, which were important fishery resources for the nation, in 1932. However, the export was halted after bullfrogs sold to the United States in 1969 were found to have been contaminated by pesticides. Now, bullfrogs are being exterminated as invaders that threaten indigenous species. We conducted interviews regarding the bullfrog hunting carried out in Toyanogata Lagoon and tried to replicate the operations.
