“…In adult lamprey, the presence of sutures can actually delay healing [23], and adults are routinely PIT-tagged without closing the incision [24]. We observed that wound closure could occur within 2 weeks for lamprey held in the laboratory at 14 °C, but that healing rates were quite variable among individuals.…”

Background: Little is known of the larval biology of Pacific lamprey (Entosphenus tridentatus), a species of conservation concern. With miniaturization of passive integrated transponder (PIT) tags, researchers now have the potential to individually mark larval lamprey. However, recent studies with sea lamprey (Petromyzon marinus) ammocoetes indicated that mortality was unacceptably high after surgical implantation of these tags. We examined survival, tag retention, growth, and swimming performance of Pacific lamprey ammocoetes tagged with uniquely coded 8.4-mm PIT tags and controls marked with visible implant elastomer (VIE).Results: Ammocoetes as small as 71 mm in length were PIT-tagged. Of the 99 PIT-tagged individuals, four died (4%) and two lost their tags (2%) within 2 months of tagging. In this period, controls had 5% mortality and 15% VIE mark loss. Incisions were completely healed within 3 months of tagging, and mean specific growth rate during this period did not significantly differ between treatment groups. Ammocoetes bearing a PIT tag did not exhibit significant reductions in swimming performance relative to controls. Conclusions:We attribute the success of this tagging effort to changes in tag implantation technique, including use of a lateral incision and no sutures. The ability to individually mark wild larval lamprey will allow research on individual growth rates, environmental effects on growth and metamorphosis, timing and rates of movement, and, ultimately, stage-specific survival.

“…In comparison, 26% of radio-tagged lampreys in the Johnson et al (2012) study and 11% of those in Moser et al (2002) were never detected at Bonneville Dam after release downstream, on average. Potential effects include differences in handling stress (e.g., Close et al 2003) or increased susceptibility to postsurgery infection (e.g., Mesa et al 2011) during the later stage of migration or at the higher water temperatures lampreys encountered at McNary Dam relative to Bonneville Dam. However, we cannot rule out the possibility that capture, handling or tagging effects were higher for adults tagged at McNary Dam than for those tagged at Bonneville Dam.…”

Low dam passage rates of adult Pacific lamprey (Entosphenus tridentatus) during upstream spawning migration have been implicated in the species' steep decline in the interior Columbia River basin. In this 2000-2010 study, we used radiotelemetry to evaluate potential predictors of lamprey passage success at McNary Dam, located~469 river kilometres (rkm) from the Pacific Ocean. The tagged population included 276 lampreys collected at McNary Dam and 53 collected at Bonneville Dam (rkm 235) that migrated to McNary Dam. McNary Dam passage efficiency was similar for the two samples, with multiyear estimates of 0.65 and 0.75, respectively. Largerbodied lampreys and those with earlier migration timing were more likely to return to McNary Dam after release, to pass the dam and to be detected upstream from McNary reservoir. Far more lampreys entered the upper Columbia River than the Snake River, suggesting that environmental cues (e.g., water discharge, temperature) or conspecific cues (e.g., pheromone concentrations) affect lamprey distribution above this large confluence. Overall, results indicate that Pacific lamprey passage success at barriers depends on a combination of individual lamprey traits plus seasonal and site-specific effects on behaviour.

“…This study operated under the assumptions that the behaviour and survival of the tagged lamprey was not affected differently from the larger, untagged population, and none of the tags were shed. Surgery and tag effects on adult Pacific lamprey have been considered extensively by other researchers in the laboratory (Close et al, 2003;Mesa et al, 2003Mesa et al, , 2011 and in the field (Moser et al, 2007). These studies suggest that while tag effects cannot be completely ruled out, these effects on lamprey behaviour are minimal.…”

Adult Pacific lamprey (Entosphenus tridentatus) were counted using consistent methodology since 2005 with a video monitoring system as they passed Leaburg Dam (McKenzie River, Oregon, USA) en route to upstream spawning areas. In this study we evaluated the detection efficiency of the video system and upstream distribution of Pacific lamprey using the video counts of lamprey passage (herein, “dam counts”), passive integrated transponder (PIT) tags, and radio telemetry. In 2019–2020 we collected, tagged and tracked 32 adult lamprey (4 from the McKenzie River and 28 that were translocated from Willamette Falls). All fish were tagged and released into the tailrace of Leaburg Dam in June 2019. Oregon Department of Fish and Wildlife employees and volunteers from the local community conducted mobile radiotracking above and below the dam in drift boats (114 mainstem river kilometers) and on foot (several tributaries). The estimated detection efficiency for dam counts was 92% (95% confidence interval: 67%–99%). Fifty percent (16 of 32) of the tagged lamprey passed the dam, including 13 of 28 that were translocated. Thirty‐seven percent (6 of 16) of lamprey that passed Leaburg Dam were detected in a restored reach of the South Fork McKenzie, 32.6 river kilometers upstream of the dam.
