Influence of environmental parameters on bacterial levels in seawater of captive green sea turtle (Chelonia mydas) larvae

Thanaporn Chuenim, Phantitra Penpan, and Kamolchanok Panishkan

At the Sea Turtle Conservation Center in Chonburi province, Thailand, bacterial infections are the main cause of high mortality in young sea turtles. The attempt is to identify the causes of bacterial accumulation and contamination and reduce the number of infections. The aim of this study is to determine the effect of live rock and rearing parameters on microbiological water quality. Microbiological results showed that the presence of live rock in the rearing containers of young green sea turtles reduced hemolytic bacteria in the seawater. Furthermore, it was found that high rearing density of reared animals influenced the increase in bacterial levels in the water and water temperature also influenced bacterial growth. The results of this study suggest that rearing environment has a significant effect on bacterial levels in the water, which should be taken into consideration in the management of not only sea turtles but also other aquatic animals.
