Main Article Content
Abstract
This study aimed to investigate the efficiency of epoxy and para rubber glue for attaching artificial satellite tags to juvenile green sea turtles (Chelonia mydas). Two groups of 10 juvenile C. mydas each were monitored for two months before and after tag attachment. Measurements and analyses of straight carapace length (SCL), straight carapace width (SCW), weight, and behaviors were conducted. The results showed that there were no significant differences in the final SCL, SCW, and weight of the turtles between the two adhesive treatments. However, the average daily gains in SCL and SCW were significantly different before and after the attachment of epoxy. The most frequently observed behavior in both adhesive groups was buoyancy, which decreased in frequency after tag attachment in both treatments. Other behaviors, such as scratching, startle responses and underwater movement also exhibited changes after attachment, varying with the type of adhesive used. The study demonstrated that natural adhesive materials serve as an alternative method for attaching satellite tags to rapidly growing juvenile sea turtles, minimizing injury and maintaining flexibility to prevent changes in carapace shape. Overall, the findings suggest the potential for using natural adhesive materials in future satellite tagging efforts to minimize negative impacts on sea turtles.
