Problems solved by technology

[0003] However, in the prior art, the method of immersing solidified fish in formaldehyde solution is often used in the formaldehyde immersion of fish specimens. Some fish specimens with large body size and high gravity are due to long-term leaching and preservation during the immersion preservation process. Time is prone to deformation due to its own gravity, and fish fins and other parts are easy to shrink and deform, resulting in the inability to fully display some important identification features, which greatly affects the viewing of specimens and the reference of scientific research

Embodiment 1

[0042] A method for displaying spindle-shaped or lateral flat-shaped fish specimens soaked in formaldehyde, comprising the following steps:

[0043] (1) Specimen collection and selection: Fresh fish individuals or freshly dead fish individuals were collected, with normal body shape, moderate size, normal body color, typical main distinguishing features, and no missing body surface features (that is, complete scales without missing, each The fins are complete, the fin rays are not broken, and the fin ray membranes are not broken) as the benchmark. If there is dimorphism between male and female individuals, it is necessary to select female samples and male samples at the same time;

[0044] (2) Fixation of the sample in the abdominal cavity: for the live sample, drip eugenol (or MS-222, also known as ethyl m-aminobenzoate methanesulfonic acid, tricaine in English) and other anesthetic solutions into the mouth of the fish, and wait for the sample fish to rest , no response after ...

Embodiment 2

[0050] A method for displaying flat fish specimens dipped in formaldehyde, comprising the following steps:

[0051] (1) Specimen collection and selection: Fresh fish individuals or freshly dead fish individuals were collected, with normal body shape, moderate size, normal body color, typical main distinguishing features, and no missing body surface features (that is, complete scales without missing, each The fins are complete, the fin rays are not broken, and the fin ray membranes are not broken) as the benchmark. If there is dimorphism between male and female individuals, it is necessary to select female samples and male samples at the same time;

[0052](2) Fixation of the sample in the abdominal cavity: for the live sample, drip eugenol (or MS-222, also known as ethyl m-aminobenzoate methanesulfonic acid, tricaine in English) and other anesthetic solutions into the mouth of the fish, and wait for the sample fish to rest , no response after touching the fish body; then use a...

Embodiment 3

[0058] A method for displaying eel-shaped (cylindrical) fish specimens soaked in formaldehyde, comprising the following steps:

[0059] (1) Specimen collection and selection: Fresh fish individuals or freshly dead fish individuals were collected, with normal body shape, moderate size, normal body color, typical main distinguishing features, and no missing body surface features (that is, complete scales without missing, each The fins are complete, the fin rays are not broken, and the fin ray membranes are not broken) as the benchmark. If there is dimorphism between male and female individuals, it is necessary to select female samples and male samples at the same time;

[0060] (2) Fixation of the sample in the abdominal cavity: for the live sample, drip eugenol (or MS-222, also known as ethyl m-aminobenzoate methanesulfonic acid, tricaine in English) and other anesthetic solutions into the mouth of the fish, and wait for the sample fish to rest , no response after touching the ...

Abstract

The invention discloses a manufacturing method of formaldehyde-impregnated fish specimens for display. The method comprises the following steps: selecting and collecting specimens according to fish specimen collection specifications and standards, carrying out preliminary fixation on specimen samples from different sources, carrying out posture correction according to different body types of the specimen fishes, further fixing the display specimens with formaldehyde, selecting display specimen bottles with different specifications and matched transparent supporting devices for the fixed specimens according to different body types and sizes, punching holes in the supporting devices corresponding to the head, the back of gill cover, the front of dorsal fin, the tail fin and the like, and fixing the specimens on the supporting devices by using transparent high-elasticity fishing lines. The manufacturing method of formaldehyde-impregnated fish specimens for display has the advantages of high professional requirement degree, short manufacturing period, simple and easily available appliance materials required for manufacturing, long display and preservation time, easy display of main identification characteristics of the specimen fish, easy maintenance and transportation, no deformation after long-time display and the like, and has high reference practical value.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a method for displaying fish specimens dipped in formaldehyde. Background technique [0002] Formaldehyde is a commonly used reagent for preserving animal samples. Because it can denature proteins, it can effectively prevent animal tissue from deforming and deteriorating, thereby maintaining its original shape. Therefore, it is widely used in the preparation and preservation of animal soaked specimens, especially It is the preservation of aquatic organisms, such as fish, and these preserved specimens are used for scientific research and as display specimens. [0003] However, in the prior art, the method of immersing solidified fish in formaldehyde solution is often used in the formaldehyde immersion of fish specimens. Some fish specimens with large body size and high gravity are due to long-term leaching and preservation during the immersion preservation process. Time is prone to d...
