Description

An experimental chamber for testing the effect of artificial design factors on sea cucumber attraction. Technical Field

[0001] This invention relates to the field of artificial reefs for attracting sea cucumbers, and more specifically to an experimental chamber for testing the effect of artificial design factors on attracting sea cucumbers. Background Technology

[0002] Artificial reefs are widely used in sea cucumber farming and resource conservation as an important means of restoring marine ecosystems and increasing marine biological resources. The habitat and feeding behavior of sea cucumbers are closely related to the design factors of artificial reefs. However, traditional experimental devices used to verify the effectiveness of sea cucumber attraction have significant drawbacks: most devices can only verify a single design factor (such as only pore size or only color) in a single test. To complete multi-factor verification, multiple experimental environments need to be built, which not only prolongs the experimental cycle but also makes the experimental results highly unpredictable due to subtle differences in the experimental environment (such as water temperature and light). Furthermore, traditional devices cannot achieve simultaneous comparison of multiple factors, making it difficult to accurately determine the synergistic or interfering effects between different factors. This seriously affects the accuracy of the assessment of the sea cucumber attraction effect of design factors and hinders the development of efficient artificial reefs.

[0003] Therefore, those skilled in the art urgently need an experimental chamber that can simultaneously verify the effects of key design factors such as angle, aperture, spacing, color, and shape on the attraction of sea cucumbers. Summary of the Invention

[0004] To address the problems of single design factors, high randomness, and low accuracy in the verification of experimental devices in existing technologies, the purpose of this invention is to provide an experimental chamber for testing the effect of artificial design factors on sea cucumber attraction, which can simultaneously verify five key factors: angle, aperture, spacing, color, and shape, thereby reducing experimental randomness and improving evaluation accuracy.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an experimental box for testing the effect of artificial design factors on sea cucumber attraction, comprising an experimental box body and experimental units. The experimental box body is a regular hexagonal prism, and includes an angle fixing plate, an angle short plate, an angle boundary plate, a perforated plate, and an iso-angle fixer. The angle fixing plate is annular and has a plurality of mounting and positioning grooves evenly arranged on it. There are six perforated plates, each with a circular hole. The iso-angle fixer is circular and has a plurality of fixing grooves evenly arranged on it. There are six angle boundary plates, which are connected to the edge of the perforated plate on the inner side through the iso-angle fixer. The perforated plates and angle boundary plates are spaced apart. There are a plurality of angle short plates, which are inserted into the mounting and positioning grooves. Each perforated plate has an experimental unit whose bottom surface is flush with the edge of the perforated plate connected to its outer side through an angle fixer. The angle fixing plate has a sea cucumber placement area.

[0006] The aforementioned experimental chamber for testing the effect of artificial design factors on sea cucumber attraction includes an outer boundary plate, a stop plate, an equidistant ruler, a right-angle fixer, and a spacing plate. The equidistant ruler is provided with a spacing plate fixing groove, and the spacing plate is inserted into the spacing plate fixing groove. The outer boundary plate is inserted into the spacing plate fixing groove at the outermost edge on both sides. The stop plate is installed at the far end of the outer boundary plate through the right-angle fixer. The other end of the outer boundary plate is connected to the perforated plate through the equidistant fixer.

[0007] The aforementioned experimental chamber for testing the effect of artificial design factors on sea cucumber attraction includes two large-diameter plates, two medium-diameter plates, and two small-diameter plates arranged opposite each other. The total area of ​​the pores on the plates with different pore diameters is equal. The large-diameter plates are provided with four circular holes with a diameter of 80 mm, the medium-diameter plates are provided with 16 circular holes with a diameter of 40 mm, and the small-diameter plates are provided with 64 circular holes with a diameter of 20 mm.

[0008] The experimental chamber described above, used to test the effect of artificial design factors on sea cucumber attraction, has a center-to-center distance of 20 mm between two adjacent spacing plate fixing slots.

[0009] The experimental chamber described above, used to test the effect of artificial design factors on sea cucumber attraction, has 72 mounting and positioning slots evenly distributed on the angle fixing plate, and the included angle between the center planes of two adjacent mounting and positioning slots is 5°.

[0010] The experimental chamber described above, used to test the effect of artificial design factors on sea cucumber attraction, has 24 fixing slots on the equal-angle fixer, with the included angle between the center planes of two adjacent fixing slots being 15°.

[0011] The experimental box described above, used to test the effect of artificial design factors on the attraction of sea cucumbers, achieves the attraction effect of color and shape factors by installing the spacing plates of different colors and shapes, and achieves the attraction effect of spacing factors by adjusting the spacing of the spacing plates installed on the equidistant ruler.

[0012] The experimental chamber described above, used to test the effect of artificial design factors on sea cucumber attraction, includes a spacing plate consisting of a PVC flat plate and a PVC corrugated plate.

[0013] In the experimental chamber described above, used to test the effect of artificial design factors on sea cucumber attraction, the spacing plates with different spacing occupy the same volume in the experimental unit, the PVC flat plates of different colors occupy the same volume in the experimental unit, and the PVC flat plates and PVC corrugated plates occupy the same volume in the experimental unit.

[0014] The beneficial effects of this invention's experimental chamber for testing the effect of artificially designed factors on sea cucumber attraction are as follows: By using the main body of the experimental chamber, composed of an angle fixing plate, an angle short plate, an angle boundary plate, a perforated plate, and an equal-angle fixator, and the experimental unit composed of an outer boundary plate, a stop plate, an equidistant ruler, a right-angle fixator, and a spacing plate, five key design factors—angle, aperture, spacing, color, and shape—can be verified simultaneously without the need for multiple experimental environment setups, thus shortening the experimental cycle. Multiple factor comparisons can be completed in a single experiment. The environmental parameters such as water temperature, salinity, and light are consistent throughout the experimental chamber, reducing the interference of environmental differences on the experimental results. The experimental chamber adopts a detachable and adjustable structure, eliminating the need to disassemble the entire chamber when changing factor parameters, thereby improving experimental efficiency.

[0018] Example 1, as shown in Figures 1-10, describes an experimental chamber for testing the effect of artificially designed factors on sea cucumber attraction. The chamber includes a main body and experimental units. The main body is made of transparent acrylic material and is located in the center. The experimental units are distributed on the outer sides of the main body. The main body is a regular hexagonal prism, and there are six sets of experimental units. Each set of experimental units is connected to the outer side of each face of the main body, and each set of experimental units is independently configured.

[0019] The main body of the experimental chamber includes an angle fixing plate 1, an angle short plate 10, an angle boundary plate 2, a perforated plate, and an iso-angle fixer 5. The angle fixing plate is circular and has several mounting and positioning grooves 3 evenly arranged on it. There are six perforated plates with round holes. The iso-angle fixer is circular and has several fixing grooves 15 evenly arranged on it. There are six angle boundary plates, which are connected to the edge of the perforated plate on the inner side through the iso-angle fixer. The perforated plates and angle boundary plates are spaced apart. There are several angle short plates, which are inserted into the mounting and positioning grooves. Each perforated plate has an experimental unit with its bottom surface flush with the edge of the perforated plate connected to its outer side through the angle fixer. A sea cucumber placement area 14 is provided on the angle fixing plate.

[0020] Specifically, to facilitate testing the effects of different apertures, the orifice plate includes two large-aperture plates 403, two medium-aperture plates 402, and two small-aperture plates 401 arranged opposite each other. The total area of ​​the apertures on the orifice plates of different apertures is equal. The large-aperture plates are provided with 4 circular holes with a diameter of 80 mm, the medium-aperture plates are provided with 16 circular holes with a diameter of 40 mm, and the small-aperture plates are provided with 64 circular holes with a diameter of 20 mm.

[0021] The number of angled short plates is set on the inner side of the orifice plate corresponding to different orifice diameters to match the orifice diameter.

[0022] Specifically, to facilitate the installation of the angle boundary plate and the angle short plate, the angle fixing plate is evenly distributed with 72 mounting and positioning slots, and the included angle between the center planes of two adjacent mounting and positioning slots is 5°.

[0023] Furthermore, to improve the ease of use of the equal-angle fixer, 24 fixing slots are provided on the equal-angle fixer, and the included angle between the center planes of two adjacent fixing slots is 15°.

[0024] The experimental unit includes an outer boundary plate 6, a stop plate 7, an equidistant ruler 12, a right-angle fixer 8, and a spacing plate 9. The equidistant ruler is provided with a spacing plate fixing groove 13, and the spacing plate is inserted into the spacing plate fixing groove. The outer boundary plate is inserted into the spacing plate fixing groove at the outermost edge on both sides. The stop plate is installed at the far end of the outer boundary plate through the right-angle fixer. The other end of the outer boundary plate is connected to the perforated plate through the equidistant fixer.

[0025] The distance between the center surfaces of two adjacent spacing plate fixing slots is 20mm.

[0026] The attraction effect of color and shape factors in the experimental box is achieved by installing spacing plates of different colors and shapes, and the attraction effect of spacing factors is achieved by adjusting the spacing of the spacing plates installed on the equidistant ruler.

[0027] Spacing plates include PVC flat plates and PVC corrugated plates.

[0028] Spacing plates with different spacing occupy the same volume in their respective experimental units; PVC flat plates of different colors occupy the same volume in their respective experimental units; and PVC flat plates and PVC corrugated plates occupy the same volume in their respective experimental units.

[0029] Example 2 This example is based on the experimental box in Example 1, and describes the specific experimental process.

Experimental Preparation: The water temperature in the experimental tank was controlled at 13-18℃, salinity at 30-32‰, pH at 6.8-7.2, and dissolved oxygen at 5.7-6.8 mg / L. 20-30% of the water was replaced daily. Feeding was done at 15:00 daily, with a daily feed amount of 3-5% of the sea cucumber's body weight. The seawater in the tank was circulated 24 hours a day, and the water was changed once a week. The feed was evenly distributed during feeding to minimize its impact on the sea cucumber's aggregation behavior.

[0031] 2. Set different combinations of key factors, taking the following combination as an example.

[0032] Experimental unit combination 1: angle 10°, aperture 20mm, spacing set to 20mm, 40mm, 80mm, each part occupies 1 / 3 of the volume; combination 4 serves as the experimental verification group of experimental unit 1, with the same angle, aperture, and spacing settings as experimental unit combination 1.

[0033] Experimental Unit Combination 2: Angle 15°, aperture 40mm, colors set to black, red, blue, green, white, and transparent, each part occupies 1 / 6 of the volume; Combination 5 serves as the experimental verification group of Combination 2, with the same angle, aperture, and color settings as Experimental Unit Combination 2.

PVC plates are installed on the corresponding equidistant ruler spacing plate fixing slots so that the PVC plates with spacing of 20mm, 40mm, and 80mm each occupy 1 / 3. The spacing of experimental unit combination 4 is the same as that of experimental unit combination 1.

[0043] As shown in Figure 9, Experimental Unit Combination 2 uses PVC boards of six colors: black, red, blue, green, white, and transparent. The six different colored PVC boards are installed on the corresponding spacing plate fixing slots so that each of the six colors occupies 1 / 6. Experimental Unit Combination 5 has the same color settings as Experimental Unit Combination 2.

[0044] As shown in Figure 10, experimental unit combination 3 uses two types of spacing plates: PVC flat plate and PVC corrugated plate. The two different shapes of spacing plates are installed on the corresponding spacing plate fixing slots so that the PVC flat plate and PVC corrugated plate each occupy 1 / 2. The spacing plate settings of experimental unit combination 6 are the same as those of experimental unit combination 3.

[0045] 3. Sea cucumber release: Select 100 healthy and active sea cucumbers of uniform size (weight 20-30g, body width 1.7-2.3cm) and place them in the sea cucumber release area 14 of the angle fixing plate 1, and record the initial release time.
