Head-start wild-caught reptiles for release: Crocodilians
A study in 2002–2004 on the Narayani and Rapti rivers, Chitwan National Park, Nepal (Ballouard et al. 2010) found that approximately half of released captive reared gharials Gavialis gangeticus survived at least a year following their release. Nineteen of 36 gharials released survived approximately one year, with two surviving at least two years. Captive reared gharials were released into two different river sections in March 2002 (10 gharials) and March–April 2003 (26 gharials). Individuals were monitored by kayak in November 2002–April 2003 and November 2003–May 2004. Tags and notches on tail scales were used for identification. Gharials were from wild-collected artificially-incubated eggs. Hatchlings were reared until 4–7 years (average body size 1.5 m long) before being released.
