Abstract

PIT-tagging is commonly used in behavioural studies of fish, although long-term evaluations of effects from tagging under natural conditions are scarce. We PIT-tagged common bream Abramis brama, European perch Perca fluviatilis, pike Esox lucius and roach Rutilus rutilus, released them in their lakes of origin and recaptured them after 103-3269 days. Overall, tagged fish did not differ in condition from non-tagged fish, except for small R. rutilus that weighed less in one lake in one year. We conclude that PIT-tagging in general has negligible long-term effects on fish condition. This article is protected by copyright. All rights reserved.
