| titleOfInvention | Preparation method of material for identifying age of shark |
| abstract | The invention discloses a preparation method of a material for identifying the age of shark, which comprises the following steps: (1) extraction: taking about 3-5 vertebra from the first dorsal fin, and freezing and storing; (2) cleaning: removing muscle and connective tissue from vertebra, washing with distilled water, decocting vertebra in boiling water for 5-10min to remove hard-to-remove connective tissue, and placing in 30% H solution if connective tissue is still attached 2 O 2 Soaking in the solution for about 1-2 h, soaking in distilled water, washing repeatedly, and oven drying; (3) coarse grinding: the two sides were ground to approximately the center using 120grit waterproof and wear resistant sandpaper on a metallographic grinder to form vertebral bone slices approximately 3-5mm thick. The invention polishes the longitudinal section of the long-fin shark spinal vertebra, applies force uniformly, polishes the polished spinal bone slice and seals the slice by the sealing agent, and ensures that the wheel veins can be kept for a longer time. |
