光唇鱼植入式可视荧光标记应用评估OA

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.
