A Device for Holding Objects in the Stomachs of Fish

摘要

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.
