Here a nearly whole gizzard shad has been recovered but most of the items recovered are things like fish scales, snail shells, and hair.

Preliminary results indicate that the Lake Griffin alligators have been eating fish other than gizzard shad this year after over 1 million pounds of gizzard shad were removed from the lake in 2002. Lake Apopka alligators are fairly consistent in their prey. Usually gizzard shad and apple snails are found in their stomachs. Lake Woodruff alligators have the most varied diet, including turtles, snakes and birds, and have the most empty stomachs.

Approximately 29% of the alligators in this study had empty stomachs. Thirteen of the alligators in this study had eaten other alligators.

Some alligators need time to recover from the procedure so all are released in very shallow water or on shore.
