“…Kelican observed 50% wound closure in 2.6 weeks and 100% wound closure in 4.5 weeks in identical surgery methodology without aqua-AP. 21 Kientz achieved 100% wound closure in four weeks with similarly sized rainbow trout. 19 The presence of granulomas in this study was unexpected and particularly complicated data analysis in Experiment 3 where they occurred in 50% of the fish.…”

“…When compared to other published studies with surgery protocols similar to the present study, resolution of inflammation for sutured fish in the present study was 5 weeks earlier than results by Kientz but 4 weeks later than Huysman and Kelican. 19,21,24 Granuloma occurrence is difficult to predict but may be associated with multiple factors such as: inflammatory response to a foreign body (i.e. suture material), variable surgeon technique, and/or immune response to unapposed edges of an incision (healing by secondary intention).…”

This study investigated the effect of a single aqua-acupuncture (aqua-AP) treatment on wound healing after surgical ventral incision in rainbow trout, Oncorhynchus mykiss. Three experiments were conducted using 20 fish per experiment (10 aqua-AP, 10 non-acupuncture): 1) ventral incision closed with two sutures and insertion of an acoustic transmitter, 2) ventral incision closed with two sutures (no transmitter), and 3) unclosed ventral incision. Aqua-acupuncture was performed by injecting a 0.25 mL bleb of vitamin B12 - saline mixture intramuscularly at 4 points around the surgical site. Statistical differences between aqua-AP and non-acupuncture for survival, transmitter retention, wound closure and redness (inflammation) were conducted (p<0.05). Experiment 1 had significantly lower (p=0.007) redness scores with aqua-AP treatment when compared to non-acupuncture. In the second and third experiments, there were no significant differences in wound closure times or redness, and acoustic transmitter retention was not significantly different between treatments. Experiment 3 had granuloma formation (50% both groups) in place of skin edge closure at 6 weeks. By study termination (12 weeks), only 1 aqua-AP fish still had a granuloma compared to 4 fish in non-acupuncture (p<0.04). There were no significant differences in wound closure times (aqua-AP versus non-acupuncture). While the overall results of this study were inconclusive for wound healing time, the decreased redness (Experiment 1) and improved granuloma resolution (Experiment 3) suggest that there may be potential benefit from aqua-AP use in rainbow trout wound healing. Aqua-AP appears safe to use on fish with future research directed at technique refinement.

Tagging fishes with internal or external electronic tracking devices (acoustic, radio, satellite, or archival tags) is invaluable to behavioural, ecological, and welfare research, but may have adverse effects on the animals studied. While short‐term responses to tagging (e.g., days to weeks) have often been investigated, less information is available on longer‐term impacts (e.g., months to years) and the potential chronic effects of tagging on basic biological needs such as foraging and reproduction. Here, we synthesize existing knowledge from peer‐reviewed acoustic, radio, satellite, and archival tagging articles (n = 149) and anecdotal accounts (n = 72) from 36 researchers to assess the effects of tagging over prolonged periods. We identified a dearth of research that has specifically measured or quantified the impacts of tagging over a period longer than a few weeks or months (e.g., median experimental study duration = 33 days; n = 120 articles). Nevertheless, there was limited evidence to support a net negative long‐term impact from the implantation or attachment of electronic devices. Considerations and future research directions are discussed with the goal of generating guidance to the research community and minimizing potentially detrimental impacts to study animals. Given the global application and relevance of electronic tagging research to inform conservation and management of fishes, it is imperative for scientists to continue evaluating how tagging procedures affect animal welfare, fate, and the interpretation of tracking data.

The implantation of acoustic transmitters into the peritoneal cavity of fish is typically performed by experienced surgeons. This study compared the effectiveness of an experienced and inexperienced surgeon performing two different types of transmitter insertion techniques on rainbow trout (Oncorhynchus mykiss). The methods used were either a traditional sutured ventral incision or a novel unsutured lateral incision. There was no significant difference in surgical duration, tag retention, or fish survival between the experienced and naïve surgeon. The time to complete surgical wound closure was not significantly different between the fish operated on by an experienced or naïve surgeon, and surgeon experience had no significant effect on the duration of inflammation. However, there were significant differences between the two surgical techniques, regardless of surgeon experience. The ventral incision with sutures method took approximately three times longer to complete than the lateral incision-only method. However, complete wound closure was significantly faster in the sutured ventral incision treatment compared to the unsutured lateral treatment. Post-surgery inflammation was over seven times longer in the fish with sutures compared to those only receiving a lateral incision. Tag retention was not significantly different between the two surgical methods. The results of this study indicate that the unsutured lateral surgical technique used in this experiment can be completed with minimal training and surgical experience in contrast to the standard technique requiring sutures. These results also provide additional support to the use of sutureless surgical techniques for acoustic transmitter implantation.
