Red-crowned roofed turtle (Batagur kachuga) is a species of turtle found in South Asia. It was the type species of its former genus Kachuga.

Description

B. kachuga can weigh up to Template:Kg to lb pounds and have shells as long as Template:Cm to in 22 inches. Males reach only half the length of females. At the end of the rainy season, the heads and necks of male turtles develop a brilliant courtship coloration of red, yellow, white, and blue, with 6 distinctive bright red stripes on top of the head. [1]

Distribution

This reptile is found in Central Nepal, NE India, Bangladesh, primarily in deep flowing freshwater rivers with terrestrial nest sites in the watershed of the Ganges River and probably NW Myanmar (= Burma). Type locality: "India"; restricted by Smith 1931:131, to "N. India." [2]

The National Chambal Sanctuary portion of The Chambal River has received moderate protection since 1979 as India’s only protected riverine habitat. It is believed to be one of the last strong holds for this species, though even here, B. kachuga are rare. [3]

Threats

The large Batagur turtlesare probably the most threatened freshwater turtles in India. Their populations have been drastically reduced due to poaching for their meat and shells, accidental drowning in fishing gear, and habitat destruction by sand mining and egg predation by Jackels. [4]

Conservation

Since 2004, B. kachuga has reproduced in captivity at the Madras Crocodile Bank Trust. A total of 132 eggs were laid through 2009 with an overall viability of 69%. 75 hatchlings were produced from these eggs, with 24 young turtles sent to Uttar Pradesh for release in 2007. [4] Since 2006, the Chambal River Sanctuary Program has implemented projects to protect wild nest, collect and hatch wild eggs in hatchery conditions, raise hatchlings to {{kg to lb|1)) at about 4 years age, conduct survival and migration studies of tagged and released hatchlings and conduct surveys over Template:Km to mi of river to determine nesting locations, nesting density, nest depredation rates, and anthropogenic pressures on the turtles. [3]
