Description

Technical Field

[0001] The utility model belongs to the field of aquaculture, and in particular relates to a green symbiosis simulation device for aquatic economic organisms. Background Art

[0002] With the needs of economic development, the scale of aquaculture in my country continues to expand and the breeding density continues to increase, which requires more bait. In addition, the metabolic products of the breeding population have a greater impact on the water environment, which is not in line with the purpose of green aquaculture. Purifying the culture environment requires the introduction of other devices, which increases the hardware cost of aquaculture.

[0003] At present, the industry has proposed the concept of green symbiosis through multiple aquatic economic organisms, that is, forming a symbiotic system on the food chain through a variety of aquatic organisms, so that the metabolic products continuously produced during the breeding process can be self-consumed by the symbiotic system, thereby greatly reducing the pollution level of the culture environment.

[0004] The algae-shellfish-crab symbiotic system is a proven symbiotic system with considerable economic value. In this system, microalgae become food for shellfish and crabs, and shellfish and their excrement are also food for crabs. In addition, microalgae can not only absorb nitrogen, phosphorus and other nutrients released by the metabolism of crabs and shellfish, but also absorb CO released by the respiration of crabs and shellfish. 2 Moreover, the ecological characteristics of shellfish adsorption make its filtering, breathing, calcification, biological deposition and other processes have a great impact on the biogeochemical processes of carbon such as phytoplankton, particulate organic debris, seawater carbonate system, sedimentation and burial. Therefore, in this system, the algae-shellfish-crab system consumes metabolic products and also saves the amount of bait. However, what kind of quantitative relationship should be formed among the three types of aquaculture objects in the system is indeed a problem that needs to be solved urgently. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a green symbiosis simulation device for aquatic economic organisms, which can simulate the algae-shell-crab symbiosis system and analyze its metabolites, and finally make the most optimized configuration of the three types of breeding objects in the system according to the analysis results.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A green symbiosis simulation device for aquatic economic organisms, used for simulating an algae-shell-crab symbiotic system, characterized in that it includes: a device shell, with an intracavity partition horizontally arranged inside, the device shell forms a symbiotic chamber and a sampling chamber adjacent to each other up and down through the intracavity partition, the intracavity partition has a plurality of connecting through holes, the symbiotic chamber is connected with the sampling chamber through the connecting through holes, and the upper surface of the intracavity partition is used for breeding crabs; a microalgae supply container, hung on the top of the symbiotic chamber, the microalgae supply container has an openable and closable delivery port, and the delivery port faces the inside of the symbiotic chamber; a breeding platform, located inside the symbiotic chamber and detachably arranged on the intracavity partition, the upper surface of the breeding platform is an inclined breeding surface, and the breeding surface is used for shellfish adsorption, wherein a metabolite sampling sponge is detachably arranged in the sampling chamber, and the metabolite sampling sponge is laid flat.

[0008] Preferably, the bottom of the breeding platform has a plurality of protruding soft coupling convex plugs, and the breeding platform is arranged on the intracavity partition through the interference fit of the soft coupling convex plugs and the communicating through holes.

[0009] Preferably, the device housing is also provided with a water quality sampling pipeline connected to the sampling cavity, and the water quality sampling pipeline is opened to the outside of the device housing through a ball valve.

[0010] Preferably, a sampling drawer is provided in the sampling cavity, all the communicating through holes are located directly above the inner cavity of the sampling drawer, and the metabolite sampling sponge is laid flat on the bottom surface of the sampling drawer.

[0011] Furthermore, a water-blocking plate is provided in the sampling cavity for pulling out and inserting, and all the connecting through holes correspond to the water-blocking plate directly above, and the partition plate, the water-blocking plate and the sampling drawer in the cavity are arranged in parallel from top to bottom.

[0012] The utility model also comprises a water pump, the input port of which is communicated with the sampling cavity, and the output port of which is communicated with the symbiotic cavity.

[0013] Preferably, the microalgae supply container has a microalgae cultivation light source for illuminating the interior of the microalgae supply container.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. Because the utility model includes a device shell, a microalgae supply container and a breeding platform, the interior of the device shell is horizontally provided with an intracavity partition to form a symbiotic cavity and a sampling cavity adjacent to each other, the intracavity partition has a plurality of communicating through holes, and the upper surface of the intracavity partition is used for breeding crabs; the microalgae supply container is hung on the top of the symbiotic cavity, has an openable and closable delivery port, and the delivery port faces the interior of the symbiotic cavity; the breeding platform is located inside the symbiotic cavity and is detachably provided on the intracavity partition, the upper surface of the breeding platform is an inclined breeding surface, the breeding surface is used for shellfish adsorption, a metabolite sampling sponge is detachably provided in the sampling cavity, and the metabolite sampling sponge is laid flat, and the microalgae supply container provides algae as bait for shellfish and crabs into the symbiotic cavity through the delivery port. The shellfish and their feces are also the bait for crabs. The shellfish are adsorbed on the inclined breeding surface, and their feces can slide from the breeding surface to the crabs on the partition in the cavity. When the shellfish dies, they can no longer be adsorbed on the breeding surface, so they slide from the breeding surface to the crabs on the partition in the cavity. In addition, the microalgae are purifying the organic waste in the water environment all the time. The unpurified organic waste precipitates and falls into the porous metabolite sampling sponge through the connecting holes. Therefore, the utility model can simulate the algae-shellfish-crab symbiotic system, and realize the metabolite analysis of the three breeding objects in the system by detecting the concentration of organic waste in the system attached to the metabolite sampling sponge, and finally make the optimal configuration of the three types of breeding objects in the system according to the analysis results.

[0016] 2. Because the bottom of the breeding platform of the utility model has multiple protruding soft-bonded convex plugs, the breeding platform is set on the intracavity partition through the interference fit of the soft-bonded convex plugs and the connecting through holes. Therefore, the utility model can flexibly set the breeding platform on the intracavity partition as needed, which is convenient for the adsorption breeding of different numbers of shellfish.

[0017] 3. Because the device shell of the utility model also has a water quality sampling pipeline connected to the sampling chamber, and the water quality sampling pipeline is opened to the outside of the device shell through a ball valve, therefore, the utility model can also measure the degree of pollution of the water environment in the system, and can also conveniently discharge the water in the sampling chamber.

[0018] 4. Because the sampling cavity of the utility model is provided with a sampling drawer by pulling out and inserting, all the connecting through holes are located directly above the inner cavity of the sampling drawer, and the metabolite sampling sponge is spread flat on the bottom surface of the sampling drawer. Therefore, the utility model can collect the unpurified organic waste (mainly the metabolites in the system) in the water environment through the porous metabolite sampling sponge, and can conveniently take it out of the device housing by pulling it out to analyze the content and / or concentration of the organic waste.

[0019] 5. Because the sampling chamber of the utility model is provided with a water-blocking plate for pulling out and inserting, all the connecting through holes correspond to the water-blocking plate directly above, and the partition plate, water-blocking plate and sampling drawer in the chamber are arranged in parallel from top to bottom. Therefore, the utility model can first relatively close the symbiotic chamber and the sampling chamber through the water-blocking plate, and then send out the water in the sampling chamber separately through the water quality sampling pipe, and then extract the metabolite sampling sponge, so that the sampling and analysis process is relatively convenient and fast.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the utility model easy to understand, the following examples and drawings specifically illustrate the green symbiosis simulation device for aquatic economic organisms of the utility model. It should be noted that the description of these implementation methods is used to help understand the utility model, but does not constitute a limitation of the utility model.

[0025] like Figure 1 As shown, the aquatic economic biological green symbiosis simulation device 10 in this embodiment is used to simulate the algae-shell-crab symbiotic system. Specifically, shellfish and crabs both use microalgae as food, and crabs can also use shellfish and excrement as food.

[0026] The aquatic economic biological green symbiosis simulation device 10 includes a device shell 1, a microalgae supply container 2, a breeding platform 3, a baffle 4, a sampling drawer 5 and a water pump 6.

[0027] An intracavity partition 11 is horizontally arranged inside the device shell 1, and the device shell 1 forms a symbiotic cavity 1a and a sampling cavity 1b adjacent to each other vertically through the intracavity partition 11. The surface of the device shell 1 also has a water quality sampling pipe 1c connected to the sampling cavity 1b, and the water quality sampling pipe 1c is open to the outside of the device shell 1 through a ball valve. In this embodiment, the water quality sampling pipe 1c is presented in the form of a faucet.

[0028] Specifically, the device shell 1 is a container with an opening on the top, and the algae-shell-crab symbiotic system is implemented in the symbiotic chamber 1a; the sampling chamber 1b is used to sample the metabolic products or environmental water quality of the algae-shell-crab symbiotic system, so as to effectively obtain the ecological data of the algae-shell-crab symbiotic system, thereby serving as a basis for optimizing the configuration of the population in the algae-shell-crab symbiotic system.

[0029] The intracavity partition 11 has a plurality of communicating through holes 11 a , the symbiotic cavity 1 a is connected with the sampling cavity 1 b through the communicating through holes 11 a , and the upper surface of the intracavity partition 11 is used for culturing crabs.

[0030] The microalgae supply container 2 is hung on the top of the symbiotic cavity, and the microalgae supply container 2 has an openable and closable delivery port (not shown in the accompanying drawings), and the delivery port faces the interior of the symbiotic cavity 1a, and the microalgae supply container 2 has a microalgae cultivation light source 21 for illuminating the interior of the microalgae supply container 2. Specifically, the microalgae supply container 2 is a bottle body with microalgae cultured inside, and the microalgae can grow better through the photosynthesis of the microalgae cultivation light source 21. In this embodiment, in multiple predetermined time periods, the microalgae supply container 2 delivers microalgae into the algae-shell-crab symbiotic system through the delivery port, and the microalgae cultivation light source 21 is a rod-shaped lamp stick hung on the inner wall of the microalgae supply container 2.

[0031] like Figure 2 As shown, the breeding platform 3 is located inside the symbiotic cavity 1a and is detachably arranged on the intracavity partition 11. The upper surface of the breeding platform 3 is an inclined breeding surface 3a, and the breeding surface 3a is used for shellfish adsorption. Specifically, shellfish negatively adsorb the breeding surface 3a through attached byssus, thereby having the ecological characteristics of attachment. Once the shellfish decays or dies due to the matrix, its attached byssus can no longer negatively adsorb the breeding surface 3a, thereby sliding down from the inclined breeding surface 3a.

[0032] The bottom of the breeding platform 3 has a plurality of protruding soft-bonded plugs 3b, which are correspondingly inserted into the connecting holes 11a of the intracavity partition 11 to form an interference fit, so that the breeding platform 3 can be detachably arranged on the intracavity partition 11. Specifically, detachability means that the position of the breeding platform 3 in the symbiotic cavity 1a and the number of arrangements can be arbitrarily set according to actual needs. The more breeding platforms 3 are arranged, the larger the breeding surface 3a and the smaller the exposed surface of the intracavity partition 11 in the symbiotic system. Therefore, the proportion of the living space of shellfish and crab populations can be changed by changing the ratio of the breeding surface 3a and the exposed surface of the intracavity partition 11, that is, it is convenient to provide sufficient living space according to different proportions of populations in the symbiotic system.

[0033] like Figure 3 As shown, the device housing 1 where the sampling cavity 1b is located is provided with a water-blocking plate 4 and a sampling drawer 5, and the cavity partition 11, the water-blocking plate 4 and the sampling drawer 5 are arranged in parallel from top to bottom, and all the connecting through holes 11a are directly above the water-blocking plate 4 and the inner cavity of the sampling drawer 5. The bottom surface of the inner cavity of the sampling drawer 5 is paved with a porous metabolite sampling sponge (not shown in the drawings), and the metabolite sampling sponge can be taken out from the sampling drawer 5. Specifically, the surface of the device housing 1 where the sampling cavity 1b is located has two elongated through holes, so as to provide a partition. The water plate 4 and the sampling drawer 5 are pull-out settings. When the water baffle 4 is inserted into the sampling chamber 1b, the water baffle 4 blocks all the connecting through holes 11a, so that the symbiotic chamber 1a and the sampling chamber 1b are physically isolated. In this embodiment, the through holes corresponding to the water baffle 4 on the device shell 1 are provided with elastic plastic sheets that open in a single row toward the sampling chamber 1b. When the water baffle 4 is inserted into the sampling chamber 1b, the water baffle 4 pushes the elastic plastic sheet open and enters. After the water baffle 4 is pulled out from the sampling chamber 1b, the elastic plastic sheet can be tightly covered on the through holes under the action of the water pressure inside the sampling chamber 1b.

[0034] The input port of the water pump 6 is connected to the sampling chamber 1b, and the output port is connected to the symbiotic chamber 1a. Specifically, the water pump 6 allows the water in the relatively closed aquatic economic biological green symbiosis simulation device 10 to circulate continuously.

[0035] The sampling and sampling recovery process of the aquatic economic biological green symbiosis simulation device 10 is described below in conjunction with the embodiments:

[0036] First, the water blocking plate 4 is inserted into the sampling chamber 1b to isolate the symbiotic chamber 1a from the sampling chamber 1b.

[0037] Next, by opening the water quality sampling pipe 1c, the water flowing into the sampling chamber 1b from the symbiotic chamber 1a is sampled. This water is the environmental water of the algae-shell-crab symbiotic system. After the sampling is completed, all the remaining water in the sampling chamber 1b is discharged. The detection content of the environmental water is specifically the extraction and identification of the environmental DNA of the water body, which aims to obtain the community abundance and community composition of microorganisms derived from the environmental water of the algae-shell-crab symbiotic system, and use it as the basis for adjusting the proportion of biological populations in the algae-shell-crab symbiotic system.

[0038] Then, the sampling drawer 5 is pulled out from the sampling cavity, and the metabolite sampling sponge is taken out. The metabolite sampling sponge is adsorbed with feces constituting the biological population in the algae-shell-crab symbiotic system. By analyzing the feces, it is intended to obtain indicators of the nutrition, digestion, metabolism and health levels of the three constituent organisms in the algae-shell-crab symbiotic system corresponding to the feces, and by analyzing the density of specific environmental beneficial bacteria species in the water body (Proteobacteria, Bacteroidetes and Firmicutes produced more by shellfish) affected by the symbiotic system organisms, it is intended to obtain the suitability of the algae-shell-crab symbiotic system for the biological population therein, and use it as a basis for adjusting the proportion of the biological population constituting the algae-shell-crab symbiotic system.

[0039] Then, the metabolite sampling sponge is laid flat on the bottom surface of the sampling drawer 5 again, and the sampling drawer 5 is inserted into the sampling chamber 1b, the water quality sampling pipe 1c is closed, and then the baffle 4 is pulled out of the sampling chamber 1b, and the water in the symbiotic chamber 1a flows to the sampling chamber 1b through the connecting hole 11a, and the elastic plastic sheet elastically closes and blocks the corresponding through hole on the device housing 1, and then the water level of the sampling chamber 1b submerges the through hole, and the elastic plastic sheet is pressed against the through hole to keep it blocked.

[0040] At this point, sampling and sampling recovery are completed.

[0041] The above-mentioned implementation modes are preferred cases of the present utility model and are not used to limit the protection scope of the present utility model. Various deformations or modifications that can be made by ordinary technicians in this field without creative work within the scope of the attached claims are still within the protection scope of this patent.
