Fish Surgery and Transmitter Encapsulation

We are providers of professional fish surgery and 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. We have implanted radio-transmitters, acoustic transmitters, combined acoustic radio transmitters (CART) into 27 species of freshwater and marine fishes (as of 2012).

The following list of fish species have been successfully tagged with biotelemetry, radio-telemetry and sonic telemetry transmitters and/or sensors using internal and external surgical techniques for various international projects by Biotactic:

1) White Sucker - Catostomus commersoni
2) Smallmouth Bass - Micropterus dolomieu
3) Largemouth Bass - Micropterus salmoides
4) Northern Hog Sucker - Hypentilium nigricans
5) Blue Sucker - Cylcleptus elongatus
6) Razorback Sucker - Xyrauchen texanus
7) Northern Pike - Esox lucius
8) Greater Redhorse - Moxostoma valenciennesi
9) Shorthead Redhorse - Moxostoma macrolepidotum
10) Walleye - Sander vitreus
11) Brook Trout - Salvelinus fontinalis
12) Brown Trout - Salmo trutta
13) Coral Trout - Plectropomus leopardus
14) Rainbow trout - Onchorynchus mykiss
15) Rock Bass - Ambloplites rupestris
16) Pumpkinseed - Lepomis gibbosus
17) Bluegill - Lepomis macrochirus
18) Black Crappie - Pomoxis nigromaculatus
19) American Eel - Anguilla rostrata
20) Sea Lamprey - Petromyzon marinus
21) Spotted Gar - Lepeosteus oculatus
22) Atlantic Salmon - Salmo salar
