“…PSAT tagging of longfin eel (Anguilla dieffenbachii) revealed a high rate of tag loss, with only three of 10 tags providing data [54]. Results from 275 silver European eel (A. anguilla) released on European coasts equipped with PSATs to study the ocean spawning migration indicated a large premature tag release [19]. This was partly related to mechanical tag loss, but also to a high predation rate (>20 % confirmed predation of eels with PSATs).…”

“…Thus definitive records of external electronic tag retention, gained from recapture or direct observation, are most easily recorded in shallow, accessible environments, notably freshwater and clear inshore, marine environments. The recent, rapid development and application of pop-up tags has encouraged greater attention to effective attachment methods due to the high proportion of premature (before the pre-set time) releases when the attachment fails [7,19]. However, problems with retention of radio, acoustic, and data storage tags may be just as evident across many species in freshwater habitats.…”

“…Mean time from tagging to premature tag release was 14-21 days (maximum 9 months). In a laboratory test of four different attachment methods for PSATs on European eel, Økland et al [19] observed an overall tag retention after 6 months of 54 %. Retention varied from 0 to 100 % among the attachment methods, but the method that achieved no tag loss was regarded as less suitable because of a strong negative reaction (the tagged fish were struggling to try to shed the tag and did not swim normally) in the first 2 days after tagging and showed consequent damage to the swimming musculature.…”

“…When using PSATs, tag retention until the planned release date is a crucial element of experimental planning and has been difficult to achieve across a wide variety of taxa [7,19,54]. This is particularly so for migrating eels, which in the early stages of sea migration inhabit highly structured environments.…”

“…In the field, retention of electronic tags is most often demonstrated by recapture, which can be habitat-and sampling efficiency dependent. Alternatively, tag loss may be demonstrated by premature release and reporting of pop-up tags [7,18,19]. Double tagging, where a conventional tag or PIT tag is used in combination with the main telemetry tag, can provide estimates of tag retention for recaptured fish.…”

The use of external electronic tags on fish: an evaluation of tag retention and tagging effects

et al. 2015

External tagging of fish with electronic tags has been used for decades for a wide range of marine and freshwater species. In the early years of fish telemetry research, it was the most commonly used attachment method, but later internal implants became preferred. Recently, the number of telemetry studies using external tagging has increased, especially with the development of archival tags (data storage tags, DSTs), pop-up satellite archival tags (PSATs) and other environment-sensing tags. Scientific evaluations of the tagging method are rather scarce for most species. We identified 89 publications, reporting effects of external tagging for 80 different fish species, which constitute the main basis for this review. External attachment holds certain benefits compared to other tagging methods, for example, speed of application, and it may be the only option for fishes with a body shape unsuitable for surgical implantation, or when using tags with sensors recording the external environment. The most commonly reported problems with external tags are tissue damage, premature tag loss, and decreased swimming capacity, but the effects are highly context dependent and species specific. Reduced growth and survival have also been recorded, but direct mortality caused by external tagging seems rare. Most of the studies reviewed evaluate tag retention, survival, and tissue reactions. There is a general need for more research on the effects of external tagging of fish with electronic tags, but particularly there are few studies on predation risk, social interactions, and studies distinguishing capture and handling effects from tagging effects. For PSATs, especially those that are large relative to fish size, there are particular problems with a high proportion of premature tag losses, reduced swimming capacity, and likely increased predation, but there remains a paucity of tag effect studies related to the use of PSATs. Before embarking on a field study employing external tagging with electronic tags, we recommend the use of appropriate pilot studies, controlled where possible, to quantify potential impacts of tagging.

Black sea bass (Centropristis striata; BSB) are a commercially managed species with an increasing population in the Northwest Atlantic Ocean. Understanding their movement ecology can be difficult due to their wide distribution and ability to inhabit both inshore and offshore reef habitats. BSB have been studied using a range of tagging techniques, and here we present the results of the first deployments of pop‐up satellite archival tags (PSAT) on this species. During 2019 and 2021, we conducted four fishing trips within the southern Mid‐Atlantic Bight region of the NW Atlantic and tagged a total of 30 fish with T‐bar tags and external data loggers, of which 4 received a PSAT and the rest received a Star‐Oddi conductivity–temperature–depth (CTD) archival tag. All PSATs transmitted some data, with short attachment durations (8–32 days) relative to the programmed release of 250 days, and we did not recover a Star‐Oddi tag. External tag attachment techniques need to be examined and improved before continued deployment of larger data loggers on BSB.
