Studies were initiated in 1962 which involved holding objects in the stomachs of fish for extended periods of time. To accomplish this, it was necessary to construct a device which would withstand regurgitating actions without inflicting injury, and would not disrupt the normal behavior of the fish. This device consisted of a plastic rod that was attached to the isthmus of the fish and extended down the gullet into the stomach.
