Abstract
Telemetry is an emerging method to study fish ecology and a reliable tool that provides useful information for managing and conserving aquatic fauna and river habitats. However, the reliability of telemetry depends on several technical factors. Implantation of the acoustic transmitter is one of the major aspects that ensure the survivability of the animal subject when released into the wild. Studies on the technicalities involving telemetry methods are limited; therefore, this study investigated the surgical insertion of an acoustic transmitter into the peritoneal cavity of Channa lucius and Neolissochilus soroides or locally known as Bujuk and Tengas. A severity index was used to rate the appearance of surgical wounds observed on the day of release into the river. Fish mortality and complications such as bleeding were not observed in both species post-surgery. The progress and prognosis of wound healing of C. lucius were better compared to N. soroides, with generally lesser inflammation and more sutures shed. Despite visually severe inflammation on N. soroides on day-12 and day-19 post-surgery, there was a good indication that skin integuments were healing. This data suggests that C. lucius has faster wound healing abilities compared to N. soroides. All fishes implanted with the acoustic telemetry method survived up to 244 days upon release into the Tembat River, Hulu Terengganu, Malaysia, and retained the tag throughout the tracking period.
