Title: Performance Assessment of Suture Type, Water Temperature, and Surgeon Skill in Juvenile Chinook Salmon Surgically Implanted with Acoustic Transmitters

Abstract

Size reductions of acoustic transmitters implanted in migrating juvenile salmonids have resulted in the use of a shorter incision - one that may warrant only one suture for closure. However, it is not known if a single suture will sufficiently hold the incision closed when fish are decompressed and outward pressure is placed on the surgical site during passage of hydroelectric dams. The objectives of this study were to evaluate five response variables in juvenile Chinook salmon subjected to simulated turbine passage. Fish were implanted with an acoustic transmitter (0.43 g in air) and a passive integrated transponder tag (0.10 g in air); incisions (6 mm) were closed with either one or two sutures. Following exposure, no transmitters were expelled. In addition, suture and incision tearing and mortal injury did not differ between treatment and control fish. Viscera expulsion was higher in treatment (12%) than control (1%) fish. The higher incidence of viscera expulsion through single-suture incisions warrants concern. Consequently, the authors do not recommend using one suture to close 6-mm incisions associated with acoustic transmitter implantation when juvenile salmonids may be exposed to turbine passage.
