Surgical Implantation of Acoustic Transmitters in Neolissochilus soroides and Channa lucius and Post-Surgical Wound Observation to Study Fish Telemetry

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