T-bar anchor tags have been used in fish and crustacean studies, but apparently not in bivalve studies (Ogbum & Ruello 1999, Liu et al.
Observations of the tagging methods at each sampling time point indicated that t-bar anchor tags were better for use in long-term studies than plastic-laminated tags glued to the top shells of the oysters.
Although t-bar anchor tags were more invasive than the plastic-laminated labels, the t-bar tags were more resistant to biofouling.
The results of this study suggest that t-bar anchor tags are a better identification method for use in longitudinal studies (15 mo in length) involving adult Crassostrea gigas than plastic-laminated labels glued to the exterior of the shell.
Most subadult red drum were tagged with internal anchor tags, which have been shown to have higher retention rates than dart tags that were primarily applied to adult red drum in our study (Bacheler et al.
