“…The encapsulation of tags in granulation tissue and the formation of a channel lined with epidermal tissue have been studied in detail in carp Cyprinus carpio L. by Bauer & Loupal (2007) and in nase Chondrostoma nasus (L.) by Bauer et al (2005), who noted that existence of pathways for pathogen entry into the body cavity of a fish may not inevitably lead to infections. In some of the recaptured brown trout, signs of inflammation and tissue necrosis at the exit of the trailing antennae were observed.…”

To test the effects of surgical implants with or without external antennae, 188 wild brown trout Salmo trutta, 150-290 mm, were tagged and released in a small river in May 2005. After 5 months, 103 of the fish were recaptured and examined. Thus, information on the relative survival, growth and general condition of each fish was obtained. The relative survival did not differ between the three groups (control, antennae and no antennae), but the specific growth of the two tagged groups were lower than that of the control fish. The tag:body-mass ratio had a significant negative effect on specific growth. A relative high occurrence of tag expulsion was observed in both treatment groups (23%). The probability to expel a tag was correlated with the tag:body-mass ratio. Finally, the relative survival, growth, expulsion rate and general condition were compared between fish tagged with different types of suture material (absorbable v. nonabsorbable). The results show only minor differences, but absorbable suture provided better wound healing and fewer expulsions.

“…Very few studies have investigated long-term histochemical effects of FITs on wild animals. A number of studies have identified persistent pathological reactions attributable to FITs, ranging from organ-invading granulation in wild carp [87] to peritoneal sarcomatosis in laboratory rats [88]. Surface coating FITs with biocompatible materials is one way to minimize inflammatory response and reduce macrophage adhesion and foreign body giant cell growth, which may also reduce delays in wound healing.…”

Best practice recommendations for the use of fully implanted telemetry devices in pinnipeds

et al. 2017

View full text Add to dashboard Cite

Electronic telemetry devices have enabled many novel and important data collection and experimental opportunities for difficult to observe species. Externally attached devices have limited retention and may affect thermoregulation, energetics, social and reproductive behavior, visibility, predation risk and entanglement. Internally placed, surgically implanted devices can mitigate some of these effects and may open additional experimental opportunities. However, improper implementation can significantly affect animals and data. From a review of recent studies using fully implanted tags and studying their effects, we present 15 specific best practice recommendations for the use of such tags in pinnipeds. Recommendations address issues including device size, coating and sterilization, implantation surgery and effect assessment, within the framework of the Three R's: Reduction, Refinement, Replacement. While developed for pinnipeds, these recommendations could apply to other aquatic mammals and vertebrates and to partially implanted or even external tags.

“…Infiltration of the reactive fibrous tissue into surrounding organs has been reported by others as well, although the potential impact of such infiltration is not known (Bauer and Loupal 2007). Additionally, because there was no obvious cellular damage in fish examined as part of this study, minimal loss of function of the affected organs is suggested, although the effect of compression or constraint of the tissues by the invasive fibrotic tissue is not known.…”

Comparative Performance of Acoustic-tagged and PIT-tagged Juvenile Salmonids

PREFACENumerous research tools and technologies are currently being used to evaluate fish passage and survival to determine the impacts of the Federal Columbia River Power System (FCRPS) on endangered and threatened juvenile salmonids. Among these are the PIT tag, balloon tag, hydroacoustic evaluation, radio telemetry, and acoustic telemetry. Each has advantages and disadvantages, but options are restricted in some situations because of limited capabilities of a specific technology, lack of detection capability downstream, or availability of adequate numbers of fish. In these situations, alternative telemetry technologies have been used to evaluate passage behavior and estimate survival. However, there remains concern about the effects of different tags or tagging procedures on fish performance.The recently developed Juvenile Salmonid Acoustic Telemetry System (JSATS) transmitter is approximately 40% smaller than transmitters previously available to researchers throughout the Columbia River Basin. The JSATS acoustic transmitter measures 13-17 mm long × 5-6 mm wide and tapers from 4 to 2 mm high. The tag weighs 0.60-0.66 g, and its coding method provides over 65,000 individual tag codes.In addition to its small size, the acoustic tag does not require the trailing antenna associated with radio transmitters, which may affect swimming performance and survival. Determining whether fish tagged with a JSATS acoustic tag can provide unbiased estimates of passage behavior and survival within the performance life of the tag is important to regional managers.Studies conducted in 2002 and 2003 evaluated the effects of the JSATS acoustic tag on predator avoidance, growth, mortality, and tag expulsion in a laboratory setting for up to a 30-d period (McComas et al. 2007). These studies found that growth and survival were similar between JSATS acoustic-tagged juvenile Chinook salmon and controls. However, effects of the JSATS tag on fish performance have not been evaluated in the field, and tag effects have not been evaluated for periods longer than 30 d.To provide additional insight on potential JSATS tag effects, a multi-agency collaborative study involving both field and laboratory evaluations was undertaken during 2006. Field work was headed by the National Marine Fisheries Service (NMFS), and laboratory evaluations by Pacific Northwest National Laboratories (PNNL) and the U.S. Geological Survey (USGS). The NMFS and PNNL compared survival and behavior of acoustic-tagged yearling Chinook salmon to those tagged with PIT tags as they migrated through the FCRPS. Separate laboratory studies by PNNL and USGS were conducted concurrently with the field work to evaluate the effects of acoustic tags on tissue response and tag loss for periods of up to 90 d. In addition, the USGS conducted iv laboratory evaluations of predator avoidance, and PNNL evaluated tag effects on growth and mortality and the minimal fish sizes appropriate for implantation of the JSATS tag.This document contains four individual reports detailing each of these s...
