1. Prepare tools and materials: prepare scalpels, tweezers, magnifying glasses, clean water, dry cloth, preservation solution (such as alcohol or formalin), etc.
2. Cleaning fishbone: Take out the skull and spine of the fish and clean them with clean water. Be careful not to damage the bone structure.
3. Boning: Put the skull and spine of the fish into boiling water, and gently take out the attached muscles and soft tissues with tweezers. This step requires patience and care to ensure that the bone surface is clean and fleshless.
4. Bleaching treatment: fish bones are soaked in 5% hydrogen peroxide solution for 2-3 days until the bone surface is completely bleached. The solution needs to be changed every day and gently stirred.
5. Re-cleaning: Take out the bleached fishbone, rinse it with clear water, and put it in a preservation solution for preservation. The preservation solution can be alcohol or formalin, and the concentration can be selected as required.
6. Finishing and preservation: put the fish bones on a dry cloth in a natural state, wrap them in cloth and put them in a specimen box. The box should be sealed and stored in a cool and dry place.
Types of fish skeleton specimens:
1, fish bones: fish bones are made by bleaching, cleaning and drying, and are usually used for exhibitions and research. This kind of specimen can be preserved for a long time, and its color and shape remain unchanged.
2. Soak the fish bones: soak the fish bones in a preservation solution, such as alcohol or formalin, to keep them fresh. This kind of specimen is mainly used for teaching and exhibition.
3. Transparent fishbone specimen: The fishbone has been specially treated to become translucent, so as to observe its internal structure and skeletal details. This kind of specimen needs degreasing and bleaching with chemical reagents.
4. Reorganization of fishbone: Reorganize fishbone into a complete skeleton structure to better show its overall shape and characteristics. This kind of specimen requires high technical level and fine operation skills.
5. Fish skull specimen: It is made by cleaning, bleaching and drying the fish skull, and is usually used for research and display. This specimen can show the bone structure of fish's teeth, gills and head.
6. Fish spine specimen: It is made by cleaning, bleaching and drying fish spine, and is usually used for teaching and display. This kind of specimen can show the spinal structure and characteristics of fish.
