Preliminary Analysis of Survival of Farm-released Alligators in Southwest Louisiana

The Louisiana Department of Wildlife and Fisheries regulates an experimental alligator (Alligator mississippiensis) egg collection program which requires the return of a portion of juvenile alligators to ensure recruitment and maintain populations. An extensive tag and release program of farm-released juvenile alligators was evaluated by analysis of later harvest of recaptured sub-adult and adult alligators. Results suggest fairly high survival rates of farm-released alligators. The minimum known alive method estimated survival to be 85.3% to 4 years post-release.
