Abstract     
The objective of this study was to define the nesting period of Phrynops hogei and determine other aspects of the ecology of this species in order to make recommendations to aid in the conservation of this endangered species. All the females captured in fyke nets were x-rayed to determine the presence and number of shelled eggs. The variation in egg size and number was correlated to the size of the female. Juvenile habitat was noted. A total of 46 females were captured, four of which were gravid, two were collected in April 2001 and the others in March 2002. The number of eggs varied from 5-7. The gravid females weighed between 2000-2800 g and ranged from 29.5 to 31.3 cm in carapace length. The clutch size, weight, and volume of eggs were positively correlated with the carapace length of the female. Gravid females were found only during the dry season. We captured two hatchlings in the Carangola Drainage, one 720 m and the other 3.72 km from the main river channel. Both were found in small streams during the rainy season. In reality we still do not know enough about the ecology of this species to recommend any management procedures.
