Description

Technical Field

[0001] This invention relates to a multifunctional sampling platform for aquatic animals, belonging to the field of aquaculture technology. Background Technology

[0002] In aquatic animal experiments, the collection of numerous samples, including blood, liver, intestines, gills, and muscles, is frequently involved. Especially in aquatic animal nutrition experiments, measurements of indicators such as body weight, length, and tissue weight are required. Typical animal or tissue characteristics also necessitate photographic documentation. Samples collected for RNA, DNA, protein, and gut microbiota testing require flash freezing in liquid nitrogen. If physiological and biochemical indicators, or enzyme activity, need to be measured, cryogenic storage is necessary. Fresh blood, syringes, and electron microscopy samples collected during the sampling process must also be refrigerated at 4°C. Furthermore, determining blood physiological and biochemical indicators requires the preparation of plasma using a centrifuge.

[0003] Currently, there is no specific equipment for sampling and testing aquatic animals. Before sampling, a lot of time and effort is often spent preparing the materials and equipment for sample collection. If some materials or equipment are found to be insufficient during the sampling process, it will directly affect the sampling quality and cause the experiment to fail to obtain the expected results.

[0004] Therefore, in order to improve sampling efficiency, reduce sampling preparation time, ensure sampling smoothness, and ensure sample safety, it is necessary to research and design a multifunctional sampling station for aquatic animals. Summary of the Invention

The sampler (5-23) has the same shape as the thickened insulation chamber body (5-22), but its diameter is smaller than that of the thickened insulation chamber body (5-22). The surface of the sampler (5-23) is covered with liquid nitrogen filter holes (5-24), and a side hook (5-25) is connected to one side. The liquid nitrogen storage chamber insulation cover (5-21) has a groove, the position of which corresponds to the position of the side hook (5-25). The low-temperature sample storage tank (5-3) includes two layers: the upper layer is a sample placement tank (5-31), and the lower layer is an ice pack placement tank (5-32).

8.

The measuring and weighing device (4-2) also includes a measuring and weighing area (4-3), a display area (4-4), a zeroing button (4-5), and a switch (4-6), with the same distribution as the tissue sample scale (4-1); it also includes a baffle (4-7), which is located on one side of the measuring and weighing area (4-3), and the measuring and weighing area (4-3) has a scale.

9. The application of the device according to any one of claims 1-8, characterized in that: It is applied to the sampling, storage, and recording of aquatic animal samples.

10. The application of the device as described in claim 9, characterized in that: The samples include tissue samples such as blood, liver, intestines, gills, kidneys, and muscles; the tests include body weight, body length, and tissue weight.
