Fingerling striped bass (Morone saxatilis) of two year classes were tagged in four body locations with coded wire tags and on two locations with Microtaggants (laminated plastic particles containing layers of fluorescent and magnetic material). Retention of coded wire tags ranged from 33% for tags in the nose to 100% for tags in the cephalic portion of the adductor mandibularis (a small muscle located below the eye). Twenty percent of the fish tagged with Microtaggants in 1982 retained tags after 471 d; 98% of the ones tagged in 1983 retained Microtaggants after 270 d. Fingerling blue tilapias (Tilapia aurea) were tagged on the body with Microtaggant particles and in the nose and epaxial muscle with coded wire tags. After 328 d, retention was 11% for Microtaggants. Coded wire tag retention was 93% for tags in the nose, 94% for tags in the epaxial muscle anterior to the dorsal fin, and 88% for tags in the muscle posterior to the dorsal fin. For striped bass, implantation of coded wire tags in the adductor mandibularis is recommended for long‐term tag retention. Implantation of coded wire tags in the nose is recommended for blue tilapia for long‐term retention. Microtaggants are not recommended for long‐term tagging of either species, but are appropriate for short‐term studies of 1 year or less.
