AbstractRedtail culter Culter mongolicus, a threatened piscivorous fish species in China's inland waters, has exhibited serious population decline. As part of a stock enhancement research project in shallow lakes of the Yangtze River basin, China, we evaluated the performance of coded wire tags (CWTs) for marking juvenile redtail culter. Through a short-term indoor experiment, we marked hatchery-reared juveniles from three size groups (mean +/- SE, small: 46.85 +/- 0.67 mm, intermediate: 53.76 +/- 0.62 mm, large: 63.42 +/- 1.05 mm) in the dorsal muscle with CWTs and tested whether marking effects on tag retention and mortality were size-specific. Tag retention was more than 98% in all the three size groups and appeared to be unaffected by fish size. Tag losses were found only within 3 d of marking. Tagging-induced mortality of small marked juveniles (58%) was significantly higher than those of intermediate (5%) and large (1%) marked juveniles and was also significantly higher than small unmarked ones (17%). The relationship of marked mortality and total length was quantitatively described by an exponential decay model. Mortality in small marked juveniles occurred mainly within 24 h after marking, which accounted for 71% of the mortality in this marked size. In order to avoid high posttagging mortality and biases in stocking assessment programs, we suggest it is worth the extra fish-culture costs to use juveniles of at least 57 mm (which displayed 90% survival in our experiment) for stocking assessment programs that utilize CWTs for a handling-sensitive species like redtail culter.; Redtail culter Culter mongolicus, a threatened piscivorous fish species in China's inland waters, has exhibited serious population decline.
