Abstract | Comparison of small fingerling Guadalupe bass Micropterus treculi (25-38 mm total length, TL) implanted with coded wire tags 1.1 mm long x 0.25 mm in diameter in the cheek (N = 210) and nape (N = 190) musculature yielded 89% and 94% tag retention after 5 d, respectively. Nape musculature provided a larger target area than cheek musculature, which made tagging easier. Coded wire tags were then inserted into the napes of 31,500 largemouth bass M. salmoides (32-54 mm TL) to evaluate this location for marking large numbers of small fingerlings. Tag retention did not differ between 24 and 48 h, averaging 97% with pooled data. A subsample of fish randomly selected throughout tagging retained more than 98% of their tags at 27 d and lost less than 1% between 27 d and 9 months. Tagging-induced mortality was low after 24 h (mean = 2%, SD = 1%). The tagging rate for each tagging machine ranged from 389 to 583 fish/h. Nape musculature provided a viable tagging location for marking relatively large numbers of small fingerling black basses with coded wire tags. |
