“…Such a high tag loss rate is greater than the accepted value for juvenile salmonids, which is usually below 10% [3,14,19,20,22,23]. The majority of 32 mm tag loss occurred among smaller individuals and was most likely caused by limited body cavity capacity.…”

“…In juvenile salmonids, the impact of smaller PIT tags (11 to 12 mm) on growth and mortality have generally been negligible (for example, brown trout Salmo trutta [3]; Atlantic salmon Salmo salar [19]) and tag retention rates are usually high (that is, 97% to 100% [3,19,20], see [21] for an exception). The efficacy of 23 mm PIT tags has also been tested among different species of juvenile salmonids (Atlantic salmon S. salar [10,22]; coho salmon Oncorhynchus kisutch [20]; steelhead O. mykiss [14,20,23]). For instance, Bateman and Gresswell [14] examined growth and survival of steelhead (73 to 97 mm FL) following intracoelomic surgical implantation of 23 mm tags.…”

Background: A laboratory experiment was conducted to assess the potential impacts of surgically implanted 23 and 32 mm passive integrated transponder (PIT) tags on survival, growth, and body condition of juvenile Atlantic salmon Salmo salar. Rate of tag retention and healing of the tagging incision were also evaluated. Atlantic salmon of three different size classes (I: 80 to 99 mm fork length (FL), II: 100 to 119 mm FL, III: 120 to 135 mm FL) were allocated to each of five experimental treatment groups: control, sham-operated (surgery without PIT-tag implantation), 23 mm PIT-tag implantation with and without suture closure of the incision, and 32 mm PIT-tag implantation without suture closure. Results: Over the 35-day experiment, mortality occurred only among fish tagged with 32 mm PIT tags (14%) and all fish larger than 103 mm FL survived. Non-sutured Atlantic salmon between 80 and 99 mm FL implanted with 23 mm PIT tags had a significantly lower mean specific growth rate of mass compared with untagged (control and sham-operated) and sutured conspecifics. However, no significant difference in growth was found between untagged fish and 23 mm PIT-tagged fish 100 to 135 mm FL. Implantation of 32 mm PIT tags decreased growth in all size classes. Regardless of size class, body condition of the fish was not affected by PIT tagging. Retention rates of 23 mm PIT tags with and without suture closure were 100% and 97%, respectively; retention of 32 mm PIT tags without suture closure was 69%. At the end of the experiment, tagging incisions without suture closure were generally well-healed. Fungal infection and inflammation around the incision site occurred only when suture was used, in 46% of size class I, 21% of size class II and 38% of size class III.

“…Within periods, we only found PIT tag retention rate to be significantly influenced by fish size during the first period after tagging, with smaller fish having lower retention rates. Size-dependent retention rates of PIT tags have previously been reported for juvenile stages of brown trout (S. trutta) [11] and steelhead trout (Oncorhynchus mykiss) [12]. The tag retention rates found in this study are similar to those reported by Knudsen et al [6] on juveniles Chinook salmon (Oncorhynchus tshawytscha) over durations of 1-2 months (98%), but higher than for adults in the same study (82%) over durations ranging from 18 months to 4 years.…”

Background: Passive integrated transponder (PIT) tags are widely used in studies of various aspects of fish survival, movement and behaviour. Quality of such studies depends on the fish retaining the tags over the study period and that the tagging procedure or the tag does not influence behaviour or survival. Here we document PIT tag retention rates in hatchery-reared Atlantic salmon over a 533-day period from the late juvenile freshwater stage (pre-smolts) to young adults after 1 year in seawater. Fish were marked with 12-mm PIT tags, injected into their body cavity, as age 1+ pre-smolt and scanned for presence of PIT tags five times during the study.Results: Tag retention for the entire period was 91% and varied between periods (96.09-99.89%). For individual time steps, daily retention rate was lowest in the first period following tagging (days 0-49). After this period retention rate increased substantially, before again dropping close to initial levels at the two last periods (days 173-533). Length of fish was only significantly related to retention during the first period. No difference in retention rates was found between males and females. A subset of fish without detected tags was X-rayed to verify that lack of PIT detection was due to tag loss. Conclusion:The retention rates observed in this study clearly show that tag loss needs to be accounted for when analysing PIT tag data on Atlantic salmon. Further, the temporal changes in retention rate clearly challenge previous assertions that tag loss is something that primarily occurs shortly after tagging or during spawning.

“…PIT tags have been used in markÁrecapture studies on a range of animal groups, including mammals, birds, reptiles and amphibians (reviewed in Hill et al 2006). While RFID techniques have been more popular in studies of vertebrates, there has been recently increased application of this technology in invertebrate research.…”

Use of adhesives to attach devices to invertebrates: implications for depredation by ship rats (Rattus rattus)

A method of marking wildlife for markÁrecapture studies should be long lasting, dependable and discreet. The use of radio frequency identification in studies of hard-shelled gastropods is a promising technique for recognition of individuals. Passive integrated transponders (PIT tags) can be attached to snails with easy-to-use adhesives (glues). However, anecdotal evidence suggests that the use of adhesives may attract predatory rats to tagged snails. In this study, we presented ship rats with empty Powelliphanta traversi tararuaensis land snails with PIT tags attached using three different adhesives. We measured the number and duration of any behavioural interactions associated with foraging directed towards different adhesives. We found that rats interacted more with shells that had Loctite † adhesive, and recommend that this glue should be used with caution in a field setting, as it may predispose marked snails to depredation by rats. Selleys Liquid Nails † appears to be the best adhesive choice for field-based studies.
