Problems solved by technology

Liquid immersion specimens are generally soaked in alcohol, formalin and other preservation solutions, but due to the limitations of the storage container and the soaking capacity of the preservation solution, the preservation effect of the immersion specimens is poor or cannot be preserved at all; the current dry specimens There are defects such as distortion, poor appearance, rough outer skin treatment and short shelf life.

Embodiment Construction

[0026] In the present invention, the skin of the sample is slit on the ventral surface of the sample, soaked in alcohol, treated with arsenic trioxide for anticorrosion, and made of a wooden inner tube mold, shaped under the guidance of experts in marine taxonomy, and dried naturally. Include the following steps (taking the Chinese ray sample with a body length of 40 cm as an example), such as Figure 4 Shown the present invention group fan ray structure schematic diagram (back view):

[0027] 1) Select a fresh fan ray sample with no skin damage, and clean the surface with clean water. Measure the length, width, and height (thickness) of the fish body, and take pictures of the shape and shape of the sample for future reference.

[0028] 2) From the position 2-3 cm behind the sample port 3, along the midline of the ventral surface backward to the point opposite to the first dorsal fin 5, use a scalpel to cut the sample perpendicular to the body surface. If the midline has a sp...

Abstract

The present invention relates to the field of marine biota specimen preparation technology, in the concrete, it relates to a method for making ray or eagle yay fish into specimen. Said method includes the following several steps: opening middle seam on sample fish abdomen, dressing, soaking the sample fish in alcohol, using arsenic trioxide to make treatment, making wooden internal model, shaping, forming and naturally drying by airing.

Description

technical field [0001] The invention relates to a technique for preparing marine biological specimens, in particular to a method for making specimens of ray or ray fish. Background technique [0002] Rays belong to the order Chondrichthyes Rays and Electric Rays, commonly known as boss fish, and rays belong to Chondrichthys Rays, among which the wingspan of Manta rays can reach more than 3 meters, commonly known as sea monsters. Both types of fish are cartilaginous fishes with flattened dorsal and ventral surfaces. Due to its weird shape, in addition to being edible, more and more aquariums and museums use them as ornamental fish. Except for individual species that can be kept in aquariums, most species are made into specimens for viewing due to their living habits and cost. Liquid immersion specimens are generally soaked in alcohol, formalin and other preservation solutions, but due to the limitations of the storage container and the soaking capacity of the preservation s...
