Evaluation of the Impacts of Carlin Tags, Fin Clips, and Panjet Tattoos on Juvenile Atlantic Salmon
Abstract The potential impacts of marking techniques on juvenile Atlantic salmon Salmo salar were assessed in a hatchery and in the wild. Hatchery‐reared parr ranging from 12.0 to 20.8 cm were marked with Carlin tags and fin‐clipped. Anal, pelvic, or caudal fin clips were used to investigate the rat...

Anal fins showed significantly less fin regeneration than pelvic or caudal fin clips and so were used as a secondary mark in the field to investigate differences in survival and mark retention between Panjet tattoos and Carlin tags. Panjet‐tattooed and Carlin‐tagged smolts held for 24 h posthandling showed no difference in survival (97% overall), and mark retention was 100%. Recapture success was equivalent between tagged and tattooed individuals, and none of the recaptured smolts showed evidence of tag loss.
