“…Retention of T-bar anchor and PIT tags by least cisco in our study revealed differences between tag types, which is consistent with previous studies (Rude et al, 2011;Bodine and Fleming, 2014). While no PIT tags were shed by least cisco, retention of T-bar anchor tags was high until day 30 (76%).…”

“…Tagging procedures for least cisco followed standard protocols for the implantation and attachment of PIT and T-bar anchor tags, respectively (Rude et al, 2011;Bodine and Fleming, 2014). Fish in the internal implant tag group had a PIT tag (Biomark Model HPT8, 134.2 kHz, 8.4 x 1.4 mm, 0.02 g in air; Biomark, Boise, Idaho) injected into their peritoneal cavity just anterior to the pelvic fins and immediately to the right of the midventral line parallel with the long axis of the body.…”

Passive integrated transponder (PIT) and T-bar anchor tags are often used in fisheries evaluations. To collect unbiased data, tags must not alter behavior, growth, or survival and have high retention rates. We examined tag retention, growth, and survival of age-2 juvenile least cisco Coregonus sardinella over a 60-day experiment following handling, anesthesia, tagging, and recovery using PIT and T-bar anchor tags. Fish were assigned to one of 12 treatment groups (20 fish per group), with individuals first assigned to one of three tagging treatments (internally implanted PIT tag, externally attached T-bar anchor tag, no tag [control]). Tag treatment groups were next assigned to a pre-handling anesthesia treatment (clove oil or no anesthetic) and a posthandling recovery treatment (elevated [10 ppt] saline or ambient [3 ppt] saline solution). Tag retention for least cisco was greater for fish that received PIT tags (100%) compared to T-bar anchor tags (25-45%). The majority of T-bar anchor tag loss (50%) occurred between days 25 and 45 of the experiment. Fish in all treatments exhibited positive growth, with no differences among treatments for specific growth rates, Fulton condition, or survival (80-100%). Most mortality (13 of 18 fish) occurred by day 5 of the study. The lowest survival (80%) occurred for fish that were not anesthetized, received PIT tags, and recovered in a 10-ppt saline solution. Our results indicate that T-bar anchor tags are sufficient for short-term studies (<30 d) involving least cisco, but PIT tags are preferred for longer evaluations (>30 d) of this species.

“…Buckmeier and Irwin () found 71% retention after 270 d when Floy FD‐68B anchor tags were used on Channel Catfish (280–379 mm TL). Furthermore, tag retention in Blue Catfish Ictalurus furcatus (364–1005 mm TL) was 76% after 6 months (Bodine and Fleming ), and tag retention was approximately 50% after 250 d for Channel Catfish and Blue Catfish (Timmons and Howell ). Our results suggest that after approximately 6 years (2,196 d), a Channel Catfish population of tagged individuals may retain approximately 54% of the initial tags.…”

Tagging fish for mark-recapture studies is a common practice in fisheries science that is used to estimate population parameters. However, biased estimates may result from an incomplete understanding of tag retention. The objective of this study was to assess tag retention for a large-river population of Channel Catfish Ictalurus punctatus over a 2,196-d period by using both discrete and instantaneous tag-retention models. A total of 3,827 Channel Catfish were double tagged with T-bar anchor tags in the Red River of the North from 2013 to 2016. The number of tagged Channel Catfish that were recaptured from 2013 to 2019 was 227, with 177 individuals retaining both tags and 50 individuals retaining one tag. Tag retention was estimated at 88% over the study interval by using a discrete tag-retention estimator. An instantaneous tag-retention model suggested that initial tag retention was high, while instantaneous tag shedding was 0.00028 (95% CI = 0.00021 to 0.00038). Based on the instantaneous model, tag retention was predicted as 90% (95% CI = 87% to 93%) at the end of the first year and 54% (95% CI = 44% to 64%) at the end of the study interval. When instantaneous estimates of tag retention are obtained, T-bar anchor tags may be appropriate for studies that evaluate population parameters for Channel Catfish over extended periods.

“…Aside from freeze brands, additional techniques that have been used to mark ictalurid catfishes include plastic tags implanted through dorsal musculature and pterygiophores (Greenland and Bryan 1974;Timmons and Howell 1995;Buckmeier and Irwin 2000;Quinn et al 2012), PIT tags (Moore 1992;Bodine and Fleming 2014), coded wire tags (Heidinger and Cook 1988), and subcutaneous injection of elastomers (Reeves and Buckmeier 2009;Zeller and Cairns 2010). Each method has unique advantages, disadvantages, and expected mark detectability.…”

We evaluated freeze brands on Channel Catfish Ictalurus punctatus and hybrid catfish (female Channel Catfish × male Blue Catfish I. furcatus) to determine suitability of the technique for identification of year‐class on ictalurid catfishes. Freeze brands were applied to fish in a hatchery setting, and adipose fins were removed as a secondary mark. Marked fish were stocked into two Kansas reservoirs within 3 d after marking. Fish were sampled with a suite of gear types for 3 years after the initial stocking in 2013. All captured catfish were observed for the presence of a freeze brand and an adipose fin. A logistic regression model estimated 80% brand retention for Channel Catfish through 460 d. The logistic regression model for hybrid catfish brand retention as a function of days at large was not significant, but retention remained near 80% throughout the 3‐year study period. Results suggest that freeze brands are suitable for marking Channel Catfish and hybrid catfish in natural systems when marks should be retained for at least 1 year and up to 3 years.
