Technical Field

[0001] This utility model relates to the field of fish farming sampling technology, and in particular to a multifunctional dissecting tray for fish body sampling. Background Technology

[0002] Fish sampling is divided into anatomical sampling and geometric morphological data sampling. Geometric morphological data sampling refers to measuring the fish's total length, body height, thickness, and other morphological data to assess the fish's growth. However, while anatomical sampling is performed using a dissecting tray, geometric morphological data sampling uses a hand ruler. The fish's surface has a lot of mucus, making it prone to slipping, leading to significant measurement errors and reducing sampling efficiency. Utility Model Content

[0011] As a further improvement to the above solution, the thickness measuring component includes a ruler fixedly mounted on the slider, an indicator plate and a pressure plate arranged perpendicular to the ruler.

[0012] As a further improvement to the above solution, the indicator plate and the ruler are fixed together, and the indicator plate is located below the pressure plate and at the corresponding side of the fish body; the indicator plate and the part of the fish body that contacts the anti-slip pad are flush.

[0013] As a further improvement to the above solution, a sliding element is installed between the pressure plate and the ruler, and the indicator plate, pressure plate and sliding element are all made of acrylic material; a rubber layer III is filled between the ruler and the sliding element.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. Additional aspects and advantages of this utility model will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the utility model. It should be understood that the following description is merely illustrative and not intended to limit the utility model.

[0028] The specific embodiments of this utility model are described in detail below. Example 1

[0029] Please see Figure 1-3 This embodiment provides a multifunctional dissecting tray for fish body sampling, including a tray 1, an anti-slip pad 2 laid on the tray 1, and a geometric data measurement structure.

[0030] The tray 1 has a slot for holding the fish, and the cross-sectional shape of the tray 1 is rectangular. The anti-slip pad 2 is made of PVC and is located inside the slot. Considering that the surface of the fish has a lot of mucus, it is very easy to slip and cause inconvenience to measurement. Therefore, in this embodiment, the anti-slip pad 2 is set to increase the friction between the contact surface between the fish and the tray 1, so as to avoid the fish from slipping during dissection and affecting the operation, and also to overcome the measurement error caused by the fish slipping.

[0031] The geometric shape data measurement structure is installed on the long side of the tray 1. The geometric shape data measurement structure includes two concave frames 4, sliders 5 slidably installed on the corresponding concave frames 4, a body length and body width measuring component installed on one of the sliders 5, and a thickness measuring component installed on the other slider 5.

[0032] One concave frame 4 is fixedly installed on the corresponding side of the tray 1, and the remaining concave frame 4 is fixedly installed on the corresponding other side of the tray 1. In this embodiment, the concave frame 4 provides support and guidance for the movement of the slider 5. At the same time, the concave frame 4 also acts as a handle, providing a point of force application for the overall handling of the dissecting tray.

[0033] The body length and width measuring assembly includes a measuring tape 6 and a rotating rod 7 for connecting the measuring tape 6 and the corresponding slider 5. Please refer to the relevant documentation. Figure 4-5 In this embodiment, the angle of the measuring tape 6 is adjustable based on the rotating rod 7. In the initial state, the measuring tape 6 is used to measure the body length of the fish. When the measuring tape 6 is rotated 90 degrees, it is used to measure the body width of the fish. When measuring the body width, the body length and width measuring components are moved with the help of the slider 5 to measure the maximum length from the base of the dorsal fin to the base of the abdomen, which is the near-vertical length of the fish body, i.e., the body width. The measuring tape 6 consists of a cover and a flexible measuring tape. When the measuring tape 6 needs to be used, the flexible measuring tape can be pulled out for measurement, which will not be described in detail here.

[0034] A rubber layer I is filled between the slider 5 and the corresponding concave frame 4. Based on rubber layer I, a damping fit is achieved between the slider 5 and the concave frame 4. That is, the slider 5 can only move along the frame when it is subjected to a certain pushing force, preventing displacement of the slider 5 during measurement and thus avoiding affecting the measurement results. A rotating rod 7 is inserted at the center of the corresponding slider 5, and a rubber layer II is filled between the rotating rod 7 and the slider 5. Based on rubber layer II, a damping fit is achieved between the rotating rod 7 and the slider 5. That is, the measuring tape 6 can only rotate when it is subjected to a certain rotational force, thus enabling flexible switching between length and width measurements and preventing rotation of the measuring tape 6 during measurement and thus avoiding affecting the measurement results.

[0035] The thickness measuring assembly includes a ruler 8 fixedly mounted on a slider 5, an indicator 9 perpendicular to the ruler 8, and a pressure plate 10. The indicator 9 is fixed to the ruler 8, and the indicator 9 is located below the pressure plate 10, at a position on the corresponding side of the fish body. The portion of the indicator 9 that contacts the anti-slip pad 2 is flush with the fish body. A slider is installed between the pressure plate 10 and the ruler 8, and the indicator 9, pressure plate 10, and slider are all made of acrylic.

[0036] A rubber layer III is provided between the ruler 8 and the slider. The rubber layer III enables the damping fit between the slider and the ruler 8. That is, the pressure plate 10 can only move up and down when the slider is subjected to a certain force, so as to avoid the pressure plate 10 shifting during measurement and affecting the measurement results.

[0037] The thickness measuring component in this embodiment measures the thickness as follows: the thickness measuring component is moved to the middle of the fish body to be measured, i.e. the thickest position, by using the slider 5. The position of the pressure plate 10 is adjusted until the pressure plate 10 presses on the fish body to be measured. At this time, the difference between the pressure plate 10 and the value marked on the ruler 8 indicated by the indicator plate 9 is the measured thickness of the fish body.

[0038] In summary, the dissection tray of this embodiment has the following advantages: the dissection tray of this embodiment is multi-functional, has a high degree of integration and does not take up space. It is suitable for fish dissection and can also measure the length, width and thickness of the fish at the same time, which facilitates the acquisition of morphological data of fish biological samples. Example 2

[0039] Please continue reading. Figure 6 This embodiment provides a multifunctional dissecting tray for fish body sampling. The difference between this embodiment and Embodiment 1 is that the dissecting tray further includes a restraining net 3, which is mounted on a tray 1. One side of the restraining net 3 is fixed to the tray 1, and a positioning post is fixedly installed on the tray 1. When the restraining net 3 covers the fish body, the other side of the restraining net 3 is fastened to the positioning post.

[0040] When measuring geometric morphology data of dissected fish, the fish will not move due to inactivation, so the restraint net 3 is not required. However, when measuring geometric morphology data of live fish, the restraint net 3 can be used to limit the movement of the live fish to prevent it from struggling and affecting the measurement operation. The specific usage process is as follows: Hold one side of the restraint net 3 so that it covers the live fish. The restraint net 3 is fastened to the positioning post to limit the movement of the live fish. In order not to damage the live fish, the restraint net 3 in this embodiment is made of rubber. Example 3

[0041] Please continue reading. Figure 7 This embodiment provides a multifunctional dissecting tray for fish body sampling, which differs from Embodiment 2 in that: the dissecting tray further includes a bracket 11 for supporting a photographic device, which is mounted on the tray 1. An LED light is fixedly installed on the bracket 11, located above the placement slot.

[0042] In this embodiment, a mobile phone or camera is supported by a bracket 11, and LED lights are used for supplementary lighting to take pictures of the fish for recording, thereby enriching the function of the dissection tray. The specific clamping structure is similar to the clamp on a selfie stick, which is a mature existing technology and will not be described in detail here.

[0043] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
