Alizarin red has high solubility and a good labeling effect. After impregnation staining of the juvenile Mugil cephalus, good labeling is achieved on both scales and fin spines, and the total labeling rate in fluorescence detection of all samples reaches 100%. After temporary culture for 40 d, the labeling retention rate is 100%, and thus the labeling retention effect is good. In addition, J staining and labeling the juvenile Mugil cephalus by employing alizarin red is simple in operation, can obtain a high-quality labeling effect, and can ensure the survival rate of the juvenile Mugil cephalus in the labeling process.
