Embodiment 1

[0037] (1) 25g sodium lauryl sulfate, 120g urea, 5g potassium sorbate, 3g citric acid and 5g potassium nitrate are dissolved in 500g distilled water to obtain mixed solution 1; 200g 1,2-propanediol is added in mixed solution 1 , stir evenly to obtain mixed solution 2; then add distilled water to make up to 1000g, and mix evenly to obtain color retention fixative;

[0038] (2) Color retention fixation: put the fish into a benzocaine solution with a concentration of 0.4 g / L, and euthanize to death; take out the fish body and place it in the color retention fixative prepared in step (1) for fixation 2 Days later, replace with fresh color retention fixative and continue to fix for 7 days;

[0039] (3) Anatomy and trimming: take out the fish, saw the fish body fixed in step (2) along the longitudinal axis of the fish dorsal fin from the fish head to the excretory hole, and remove one side gill cover and body wall. The visceral structures such as gills, body cavity thyroid, heart, ...

Embodiment 2

[0044] (1) 25g sodium lauryl sulfate, 105g urea, 5g potassium sorbate, 3g citric acid and 20g potassium nitrate are dissolved in 500g distilled water to obtain mixed solution 1; 200g 1,2-propanediol is added in mixed solution 1 , stir evenly to obtain mixed solution 2; then add distilled water to make up to 1000g, and mix evenly to obtain color retention fixative;

[0045](2) Color retention fixation: put the fish into a benzocaine solution with a concentration of 0.2 g / L, and euthanize to death; take out the fish body and place it in the color retention fixative prepared in step (1) for fixation 1 Days later, replace with fresh color-retaining fixative and continue to fix for 7 days;

[0046] (3) Anatomy and trimming: The fish was taken out, the fish body fixed in step (2) was sawed along the longitudinal axis of the fish dorsal fin from the fish head to the excretory hole, and one side gill cover and body wall were removed. The visceral structures such as gills, body cavity...

Embodiment 3

[0051] (1) 15g sodium lauryl sulfate, 150g urea, 2g potassium sorbate, 5g citric acid and 4g potassium nitrate are dissolved in 500g distilled water to obtain mixed solution 1; 150g 1,2-propanediol is added in mixed solution 1 , stir evenly to obtain mixed solution 2; then add distilled water to make up to 1000g, and mix evenly to obtain color retention fixative;

[0052] (2) Color retention fixation: the fish was placed in a benzocaine solution with a concentration of 0.2 g / L, and anesthetized to death; the fish body was taken out and placed in the color retention fixative prepared in step (1) for fixation 3 Days later, replace with fresh color retention fixative and continue to fix for 3 days;

[0053] (3) Anatomy and trimming: The fish was taken out, the fish body fixed in step (2) was sawed along the longitudinal axis of the fish dorsal fin from the fish head to the excretory hole, and one side gill cover and body wall were removed. The visceral structures such as gills, ...

Abstract

The invention belongs to the field of production and processing of animal specimens and particularly relates to a production method of a plasticized specimen of fish viscera. A fish body is placed ina color protecting fixing agent to be fixed, and then, the fish body is dissected and trimmed; under a vacuum negative pressure condition, the dissected and trimmed fish body is sequentially immersedin a silica gel solution for vacuum penetration, and polymerization curing is performed by a silica gel curing agent; finally, trimming is performed again, varnish is spayed on the surface, drying isperformed and the plasticized specimen of the fish viscera is obtained. The production method of the plasticized specimen of the fish viscera is simple to operate and high in feasibility, the fish body can be fixed by the environment-friendly color protecting fixing agent, and the color sense can be improved. The specimen is produced with plasticizing silica gel, has the advantages of being environmentally friendly, non-toxic, odorless, non-irritant and the like and is easy to preserve and long in preservation time.

Description

technical field [0001] The invention belongs to the field of preparation and processing of animal specimens, and particularly relates to a preparation method of a plasticized specimen of fish viscera. Background technique [0002] Fish are widely distributed in rivers, rivers, lakes and seas, with a wide variety, huge quantity and unlimited resources, providing abundant food resources for human beings. In addition, ornamental fish have a wide variety of species, bright colors, beautiful postures, peculiar shapes, and interesting habits. They have high appreciation value and have become popular pets. However, there is still a lack of information on the structure of fish, and most of the prepared specimens are immersed specimens stored in formaldehyde fixative. Due to the strong irritating odor, the inability to display the internal structure of the fish, and the small teaching use, it is urgent to produce an environmentally friendly, non-toxic and non-irritating specimen tha...
