Abstract
Turtle is a marine vertebrata that belongs to Appendix 1 category which means it is prohibited to be traded internationally. In addition there is a sea turtle one of animals that are most under threat its population is set directly or indirectly. The death of hatchlings sea turtle was caused by various factors, including natural habitat destruction, marine pollution, predatory attacks and the hunting of meat and eggs for commercial purposes. In addition, the declining number of turtle populations is also caused by fungal infections. The presence of fungi is also a problem in TCEC which causes high mortality rates of turtles (Lepidochelys olivacea). Therefore, by knowing the type of fungus that can be found to be treated as well as prevention of appropriate fungi that infect. The purpose of this study was to identify the fungus found in the turtle body part (L. olivacea) and the turtle eggshell failed to hatch. The turtle samples from turtles aged 10-14 days were obtained from TCEC Bali turtle breeding. Samples were taken later in swabbing on PDA media and incubated for 7 days. After that purification to get a pure colony. The next stage is the identification of the genus in macroscopic and microscopic at 40x and 100x magnification. The results showed that from 10 samples of fungus taken from some parts of sea turtle body such as on eyes, feet, neck and carapace, and eggshell failed to hatch during sampling, 15 isolates of fungal colonies were found. Of the 15 isolates, found 5 genera of Aspergillus sp, 5 genus of Fusarium sp, 3 genus of Pytophthora sp and 1 isolate of Trichoderma sp. In the body of the fungus is most commonly found in the neck as much as 4 colonies and each type of fungus can be found on the neck. The most common types of fungus found in eggshell shells that fail to hatch are the Aspergillus sp fungus, each of which has yellow spots on the eggshell. Apart from the eggshell that has yellow spots it is also obtained from the softened eggshell. © 2019, Yale University. All rights reserved.
