Fish Surgery, Telemetry and Transmitter Encapsulation

Above:  EMG transmitter implanted in the peritoneal cavity of a 35 cm smallmouth bass to examine physical output during fishway use.  Also shown is a series of images showing radio transmitter encapsulation in a smallmouth bass after 22 months.

Scientists at Biotactic are experts in fish surgery.  We have developed, tested and published multiple descriptions of surgical procedures for implantation of biotelemetry transmitters, electrodes, and vascular flow probes in freshwater and marine fish species.  We have invented custom surgical tools for specific research applications, and examined effects of various surgical techniques, wound-closure, and infection control methodologies relevant to fisheries research.

TRANSMITTER IMPLANTATION/ATTACHMENT AND ENCAPSULATION:

Threatened and Endangered Species:  Cycleptus elongatus - blue sucker - Texas USA

    Xyrauchen texanus - razorback sucker - Nevada USA

Lepisosteus oculatus - spotted gar - Ontario Canada

Marine Species:  Plectropomus leopardus - Queensland Australia

Freshwater Species:  Micropterus dolomieu - Waterloo Ontario
