Preparation method of primary-color and solid-phase specimen of small fish

Abstract

The invention provides a preparation method of a primary-color and solid-phase specimen of small fish. The preparation method comprises the steps: 1) anesthesia, 2) fixing, 3) buffering and 4) sealing for keeping. The preparation method 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; the method is suitable for small ornamental fish, and particularly has better keeping of black, white and red fish; and the prepared specimen is convenient to carry and observe, and has artistic appreciation and collection values.

Description

technical field [0001] The invention belongs to the field of animal specimen preparation, and in particular relates to a method for preparing a small fish primary color solid-phase specimen. 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. At present, fish soaked specimens are usually fixed and preserved in formalin solution. The disadvantages of the formalin soaking method are: 1. Since formaldehyde will continue to volatilize, formalin solution needs to be added at regular intervals for supplementation. . 2. After volatilization, formaldehyde pollutes the air and has harmful effects on the human body, which is not hygienic and safe enough. 3....

AI Technical Summary

Problems solved by technology

At present, fish soaked specimens are usually fixed and preserved in formalin solution. The disadvantages of the formalin soaking method are: 1. Since formaldehyde will continue to volatilize, formalin solution needs to be added at regular intervals for supplementation.

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

4. Inconvenient to carry

[0003] 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
