Problems solved by technology

[0003] At present, fish immersion specimens are generally preserved by 10% formalin. The disadvantages of the formalin immersion method are: 1. Since formaldehyde will continuously volatilize, formalin solution needs to be added at regular intervals. supplement
2. After volatilization, formaldehyde pollutes the air and has harmful effects on the human body, which is not hygienic and safe enough
3. Poor tissue elasticity, pale and stiff muscles
In particular, it is easy to cause the color loss of the specimen, which is not conducive to the preservation of brightly colored fish, and it is very different from the life after treatment, and cannot achieve the purpose of vivid display
[0004] On the other hand, although dried specimens have the characteristics of being able to display fish vividly, for the production of small fish morphology specimens, such as the method of filling and sewing at the same time is not only difficult to operate, but also difficult to represent the various forms of fish

Embodiment 1

[0022] 1) Anesthesia: Take the swallowtail fish that is about 5cm long and needs to be made into a specimen into a beaker, and slowly add eugenol to the beaker until the fish is anesthetized;

[0023] 2) Fixation: Take out the anesthetized fish and put them into the fixative solution, adjust the fish body, and let it stand still for 48 hours. The fixative was prepared as follows: formaldehyde 10ml, absolute ethanol 30ml, acetic acid 2ml, sodium acetate 2g, and distilled water was added to 100ml.

[0024] 3) Preservation: pour out the fixative solution, add preservation solution and seal it for storage. The preparation method of the preservation solution is 5ml of formaldehyde, 2g of sodium acetate, 20ml of glycerin, 0.1ml of eugenol, and add distilled water to 100ml.

[0025] see processing results figure 1 .

Embodiment 2

[0027] 1) Anesthesia: Take the guppies about 3cm long and need to be made into specimens into a beaker, and slowly add eugenol to the beaker until the fish is anesthetized;

[0028] 2) Fixation: Take out the anesthetized fish and put them into the fixative solution, adjust the fish body, and let it stand still for 24 hours. The fixative was prepared as follows: formaldehyde 5ml, absolute ethanol 20ml, acetic acid 2ml, sodium acetate 2g, add distilled water to 100ml.

[0029] 3) Preservation: pour out the fixative solution, add preservation solution and seal it for storage. The preparation method of the preservation solution is 2ml of formaldehyde, 2g of sodium acetate, 10ml of glycerin, 0.1ml of eugenol, and add distilled water to 100ml.

[0030] see processing results figure 2 .

[0031] Such as figure 1 , figure 2 As shown, the soaked swallowtail and guppy specimens prepared by this method still maintain the original color after two years of preservation, and the pres...

Abstract

The invention provides a preparation method of a primary-color solution preserved specimen of small fish. The preparation method comprises the steps: performing anesthesia, adding a fixing solution, correcting a fish body, performing standing and fixing, adding a preserving solution, and performing sealing for keeping. The preparation method can keep a morphological structure of the small fish for a long time, does not lose a color of the specimen, and is particularly suitable for keeping of colorful fish; a treated color and a living color of the fish are same or approximate; and a purpose of lively and visual showing is achieved. By a two-year experiment, a form of the specimen can be kept; a primary color of the fish can be kept; and the method is suitable for small ornamental fish, and particularly has better keeping for black, white and red fish.

Description

technical field [0001] The invention belongs to the field of animal specimen preparation, and in particular relates to a method for preparing small fish specimens dipped in primary colors. Background technique [0002] There are generally three types of fish specimen preparation methods: soaked specimens, bone specimens and stripped specimens. Skeleton specimens are not conducive to showing the overall shape and structure, while stripped specimens are suitable for specimens that are large in size and whose scales are not easy to fall off. Specimens are widely used. [0003] At present, fish immersion specimens are generally preserved by 10% formalin. The disadvantages of the formalin immersion method are: 1. Since formaldehyde will continuously volatilize, formalin solution needs to be added at regular intervals. Make supplements. 2. After volatilization, formaldehyde pollutes the air and has harmful effects on the human body, which is not hygienic and safe enough. 3. Poo...
