Abstract

One hundred and thirty four eggs of Olive Ridley turtle Lepidochelys olivacea (Eschscholtz) were incubated at an average temperature of 30.S°C under laboratory conditions. Thirty baby turtles emerged in three consecutive nights after S3 days of incubation. Of the remaining eggs, 69 did not hatch out and 35 failed to complete the development. Out of the 30 turtles that emerged, 28 died during the first 4 months, probably due to overcrowding and adverse conditions of the aquarium. The two turtles which survived, were reared in the aquarium for 1| years, feeding with the meat of Donax Sp., Sepia Sp. and Sardinelta sp. The morphological changes undergone and behaviour pattern of the turtles during the period of rearing were presented.
