Abstract:

In order to establish a convenient and efficient tagging technique for Acrossocheilus fasciatus to support its breeding practice and evaluate the enhancement and releasing effects, this study employed visible implant elastomer (VIE) to conduct short-term comparative trials on the effects of different VIE colors and fish sizes. The impact of tagging on the short-term growth of juvenile fish was also assessed. The results showed that the 30-day survival rates of juveniles with total lengths of (4.43±0.13) cm and (6.32±0.15) cm both exceeded 95% (98.0% and 99.5%, respectively), and the tag retention rates in both groups were 100%. However, the red VIE tags were clearer and easier to recognize with the naked eye than the green tags. Under the same rearing conditions, the 30-day survival rate, tag retention rate, and specific growth rate (SGR) of the red VIE-tagged group [with a total length of (4.43±0.13) cm] were 96.50%, 100%, and (1.17±0.16)%·d-1, respectively. No significant difference in SGR was observed between the tagging group and the control group (p>0.05). This study confirms that VIE tagging is an effective and applicable method for individual marking of A. fasciatus juveniles, with no adverse effects on their growth or survival.
