Retention of Coded Wire Tags Implanted into Cheek Musculature of Largemouth Bass

Abstract
Standard-length coded wire tags (1 mm long x 0.25 mm in diameter) were injected into the cheek musculature of 240 fingerling (47-128-mm-long) largemouth bass Micropterus salmoides. After 9 weeks, tags remained in all of the 200 surviving fish as well as in all 19 of the dead fish examined. Histological analysis indicated that the tissue surrounding the tags was healed. Cheek tagging with coded wire tags appears to have considerable potential for permanently identifying specific groups of largemouth bass.
