Problems solved by technology

[0004] Crabs belong to the phylum Arthropoda, Crustacea, and are covered with a hard carapace. These characteristics lead to the use of soaking method in the production of most crab specimens, and the soaking specimens have the following defects in practical applications: 1. Specimen preservation In a sealed container, due to the refraction of the preservation solution, there will be deviations in the observation of the details of the specimen. The container is usually sealed with wax, and it is more cumbersome to take it out for observation.
2. Second, the preservation solution has a corrosive effect. Although the specimen can be preserved for a long time, the color will fade. If you need to preserve the color, you need to configure a complex color retention agent
3. Due to the physiological structure of the crab's special open circulation, the hepatopancreas with more lipids will seep out of the carapace in flocculent form, contaminate the preservation solution, and affect the appearance
The traditional method of peeling specimens is not suitable for crabs. The carapace of crabs is composed of chitin and calcium. After long-term exposure to the air, it will gradually weather and the carapace will become as fragile as paper

Embodiment 1

[0043] The preparation of embodiment 1 Chinese mitten crab specimen (1)

[0044] Preparation of tools and reagents: dissection tools, including scissors, tweezers, syringes, keys, brushes, absorbent cotton balls, fine wire, dry towels, preservatives (formalin 5%), antiseptic powder (phenol, alum, camphor press 1 :3:0.1 weight ratio configuration).

[0045] In vivo sampling: take out the Chinese mitten crab used in the experiment, freeze it to death at -80°C, cut off the mandible with dissecting scissors, cut carefully along the seam between the carapace and the trunk, separate the carapace from the trunk, and then carefully cut it with a medicine spoon. The internal organs such as the stomach, hepatopancreas, and ovary were removed, and then a brush was used to extend from the abdomen into each appendage, remove the muscle tissue in the appendage, and use a syringe to absorb distilled water and rinse repeatedly until the muscle tissue was completely removed. Use a syringe to ...

Embodiment 2

[0046] The preparation of embodiment 2 Chinese mitten crab specimens (two)

[0047]Preparation of tools and reagents: dissection tools, including scissors, tweezers, syringes, keys, brushes, absorbent cotton balls, fine wire, dry towels, preservatives (formalin 5%, sodium salicylate solution 5%), preservative powder (Phenol, naphthalene powder, alum, and camphor are configured in a weight ratio of 1:3:3:0.1).

[0048] In vivo sampling: take out the Chinese mitten crab used in the experiment, freeze it to death at -80°C, cut off the mandible with dissecting scissors, cut carefully along the seam between the carapace and the trunk, separate the carapace from the trunk, and then carefully cut it with a medicine spoon. The internal organs such as the stomach, hepatopancreas, and ovary were removed, and then a brush was used to extend from the abdomen into each appendage, remove the muscle tissue in the appendage, and use a syringe to absorb distilled water and rinse repeatedly unt...

Embodiment 3

[0049] The preparation of embodiment 3 Chinese mitten crab specimen (three)

[0050] Preparation of tools and reagents: dissecting tools, including scissors, tweezers, syringes, keys, brushes, absorbent cotton balls, thin iron wires, dry towels, antiseptic (formalin 5%), antiseptic powder (phenol antiseptic powder).

[0051] In vivo sampling: take out the Chinese mitten crab used in the experiment, freeze it to death at -80°C, cut off the mandible with dissecting scissors, cut carefully along the seam between the carapace and the trunk, separate the carapace from the trunk, and then carefully cut it with a medicine spoon. The internal organs such as the stomach, hepatopancreas, and ovary were removed, and then a brush was used to extend from the abdomen into each appendage, remove the muscle tissue in the appendage, and use a syringe to absorb distilled water and rinse repeatedly until the muscle tissue was completely removed. Use a syringe to draw a sufficient amount of antis...

Abstract

The invention discloses a method for making a crab type aquatic livestock stripped specimen. The method comprises the following steps: separating the back shell of a crab from the abdomen of the crab, taking out internal organs and muscle step by step, and treating the emptied back shell and the abdomen in preservative liquid for 2 hours (injecting the preservative liquid into parts such as foot tips which are not easy to infiltrate by using an injector); after preservative treatment, filling appendages and the whole abdomen with cotton mixed with a preservative powder agent, recombining the back shell with the abdomen integrally according to an original outline, fixing with a rope, shaping, fixing the appendages with fine iron wires, and drying in air at a place with good air circulation; after air drying, sealing all joints of the shell by using white glue, and spraying a layer of varnish on the surface of the shell; and transferring the specimen into a special box, and vacuumizing or filling with nitrogen, thereby preserving the specimen for a long time. The method is good in specimen mold-proof and preservative effect and is worthy of promotion, popularization and application, and the specimen is natural in color after being fixed and can be applied to science popularization education and academic research, and can be also used as high-class artwork as original morphology, color and texture can be maintained for a long time.

Description

technical field [0001] The invention relates to the technical field of specimen preparation, in particular to a method for preparing crab-like aquatic animal specimens. Background technique [0002] The English word specimen comes from ancient Greek, which means "moving skin". It refers to the use of physical or chemical means to process the whole or part of animals in order to preserve the characteristics of animals for a long time, and to reshape their living body. form, bringing them to life while preserving them forever. Animal taxidermy originated in Europe in the 19th century. At that time, hunters peeled off the fur of their prey and then stuffed it to restore the shape of the animal before it was alive and enable it to be preserved for a long time. This is the prototype of taxidermy. With the development of biological sciences, the production process of specimens has also made great progress, which has played an important role in scientific research, teaching, displ...
