| Abstract |
|
The distribution of Podocnemis expansa is throughout the Amazon, Orinoco and Esequibo river basins in South America. It is the biggest hard shell, fresh water turtle in the world, and is cataloged as an endangered and vulnerable species by the International Union for the Conservation of Nature (IUCN). In captive conditions they are more prone to acquire different diseases, which in the wild were not hazardous. The main concern in farms, is to keep mortality rates low and to work towards high growth rates. It is also important to ensure that the turtles released are healthy and do not carry infectious, parasitic and genetic diseases. The clinical observations were collected from clinical evaluations and from necropsis and histopathological studies obtained from fifty neonates, two hundred twenty hatchlings and juveniles, and 7 adults. Pathological anatomy studies were performed on 4 symptomatic neonates, and bacteriological, mycological and histopathologic studies were also performed. Data was collected over a period of eight years, 1994-2001. The diseases observed in 2 farms at this Venezuelan Captive Breeding Program were classified acording to their natures in three phases neonates: congenital anomalies, omphalitis, neonatal death, mycotic dermatitis and septicemia. Hatchlings and juveniles: metabolic bone disease, vitamin A deficiency and gout. Adults: presented erosive and descamative lesions of the carapace and claws. In neonates, hatchlings and juveniles annual mortality rates reached a minimum 1.54% and a maximum 60.50% in the three phases during the period of study. Morbidity rates were 100% in adults, but morbidity was not registered in neonates, hatchlings and juveniles.
