Description

Technical Field

[0001] This utility model relates to the technical field of drug administration experiments in aquaculture, and in particular to a drug administration experimental device for aquaculture. Background Technology

[0002] With the rapid development of aquaculture, fish parasitic diseases are becoming increasingly common. For example, parasitic infections caused by anchor bream are particularly serious in freshwater fish farming, becoming a major factor restricting farming efficiency and fish health. Drug treatment remains one of the main methods for controlling anchor bream infection; however, many technical challenges remain in conducting experimental research on drug efficacy.

[0003] Research on drugs for the prevention and treatment of anchor worms largely relies on experimental evaluation through natural infection of fish and pond application. However, due to significant variations in the number and location of anchor worms on each fish, establishing a unified experimental baseline is difficult, leading to a lack of comparability in efficacy results. Furthermore, detached parasites after drug application may sink to the bottom of the pond, drift away with the water flow, or reattach to the fish or container walls, greatly interfering with the statistical analysis of key indicators such as detachment rate and mortality rate. Currently, there is a lack of standardized experimental equipment with a reasonable structure and high statistical accuracy for experimental testing of aquatic parasite efficacy, enabling quantitative analysis of parasite detachment rate, mortality rate, and toxic reactions in fish, thus ensuring that drug administration experiments in aquaculture meet scientific and objective requirements.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the embodiments of the present utility model.

[0037] Quantitative analysis of parasite shedding rate, mortality rate, and fish toxicity can be achieved by diluting the experimental agent and directly applying it to fishponds in sunny weather. However, due to the large size of fishponds, tracking fish activity is difficult, and accurate statistics on parasite mortality and shedding are challenging. Some technicians catch infected fish and conduct individual experiments in laboratory containers, but this is time-consuming and also suffers from the problem of inaccurate parasite mortality data. This embodiment of the invention will use the infection of anchor bream as an example to specifically illustrate how to conduct drug administration experiments based on the aquaculture drug administration experimental device of this invention, and how to count the number of parasite deaths.

[0038] Please see Figures 1 to 3 This utility model provides an experimental device for drug administration in aquaculture. The experimental device includes multiple drug-holding components 1, multiple pumping components 2, and multiple filters 3.

[0039] Each set of drug-containing components 1 includes multiple vertically stacked and interconnected drug-containing containers 11. The bottom of each container 11 can be an inverted conical structure or other structures that facilitate the flow of experimental drugs, such as a sloping structure. All containers 11 in each set of drug-containing containers are used to hold experimental drugs of the same composition. Each container 11 has a dispensing hole 12 at its bottom. The containers 11 can be made of plastic materials, such as transparent purified water containers. The bottom of the purified water container is cut off and discarded, and the container is then inverted to form the drug-containing container 11. Each set of drug-containing components 1 is used for repeated experiments with the same drug, supporting longitudinal experimental statistical analysis, such as comparing the effects of different application times; experiments can also be conducted on fish of different sizes, and the drug effect can be statistically analyzed based on the number of dead parasites. For example, each set of medicine-holding components 1 can be equipped with 3-5 vertically stacked medicine-holding tanks 11. After 1 hour, 3 hours and 6 hours of treatment, the number of parasite deaths can be counted to explore the parasite mortality situation under different durations.

[0040] It is understandable that the dispensing hole 12 is used to draw out the experimental reagent 5 from the medicine container 11 for circulation pumping by the pumping system, and also serves as a discharge channel for dead parasites flowing with the reagent. A fine mesh screen can be installed on the dispensing hole 12 to prevent fish from flowing out with the reagent. The diameter of the dispensing hole 12 needs to be set to balance the flow rate and ensure the circulation of the experimental reagent 5.

[0041] The number of pumping components 2 is the same as the number of drug-containing components 1. Each set of pumping components 2 is used to circulate the experimental reagent 5 in the corresponding drug-containing component 1. Each set of pumping components 2 is dedicated to one drug-containing component 1, realizing the circulation of the experimental reagent 5 among the drug-containing containers 11 in that set. The pumping components 2 can ensure uniform flow of the reagent in the drug-containing container 11, prevent the sedimentation of drugs with settling properties from causing changes in composition, and at the same time assist dead parasites to be carried to the filter 3 with the flow of the reagent.

[0042] Please see Figure 4 The filter 3 can be configured as a mesh structure, made of fine wire mesh, and fitted onto the drug outlet 12. Alternatively, the filter 3 can be a flat metal mesh, installed at the bottom of the drug container 11. The filter 3 can be fixed to the drug container 11, for example, by an adsorption clip structure or by hot melt adhesive; no specific limitations are specified here. The number of filters 3 is the same as the number of drug containers 11. Each filter 3 is installed on the corresponding drug circulation path of the drug container 11, so that dead parasites in each drug container 11 settle onto the corresponding filter 3. The filter 3 can also be configured as a mesh plate, installed on the drug outlet 12. Because the experimental drug 5 in each drug container assembly 1 flows unidirectionally under the action of the corresponding pumping assembly 2, dead parasites can enter the filter 3 with the flow of the experimental drug and settle, preventing them from flowing back into the drug container 11.

[0043] The following will describe in detail the usage of the drug administration experimental device of this utility model. When conducting drug administration experiments with different experimental reagents, different groups of drug-containing components 1 use different drugs or different concentrations of experimental reagents. Each drug-containing container 11 holds a preset number of fish infected with anchor bream, which can be one or two fish, to make the initial infection level of all fish as similar as possible. The several groups of drug-containing components 1 configured according to the experimental design are numbered, for example, group A, group B, group C, and group D, and the drug-containing containers 11 are equipped with corresponding reagent labels 13. Each group is equipped with the same number of medicine containers 11. For example, each group of medicine containers 1 is equipped with 4 medicine containers 11. The medicine containers 11 of group A are labeled A1, A2, A3 and A4, the medicine containers 11 of group B are labeled B1, B2, B3 and B4, the medicine containers 11 of group C are labeled C1, C2, C3 and C4, and the medicine containers 11 of group D are labeled D1, D2, D3 and D4. Each container is filled with an experimental reagent of a specific concentration or composition. Groups A and B can be used as example groups, and groups C and D can be used as comparative groups.

[0044] During the drug administration experiment, the pump assembly 2 was activated to circulate the drug and ensure its even distribution within the drug container 11. Parasites attached to the fish were killed by the drug, and the circulating drug carried the dead parasites to the filter 3. The experimental time was controlled, such as for 1 hour, 3 hours, and 6 hours, to observe the duration of the drug's effect and the fish's stress response.

[0045] After the designated application time, stop the cycle, remove filter 3, and count the number of dead parasites in each filter 3 of each medicine container 11. The results of different drug compositions or concentrations can be obtained by observing additional indicators such as fish health status, behavioral changes, and feeding responses. Statistical data from different drug groups and different application time points can be compared and analyzed. Finally, empty the experimental drug from the medicine container 11 and clean all components. The experiment can be repeated by changing the drug or fish as needed to increase the data sample size. Each filter 3 is independent, facilitating the counting of parasite deaths per container without the need for repeated checks on the fish.

[0046] Furthermore, the experimental apparatus also includes an experimental frame 4, which serves as a support component, bearing and securing all the medicine containers 11 to ensure stability and ease of observation. The experimental frame 4 has two rows of parallel fixing frames, meaning both layers are horizontal and parallel to each other. Each row of fixing frames has multiple frame-structured fixing cavities for placing the medicine containers 11. The experimental frame 4 can be constructed by welding angle iron or by splicing profiles, as long as it can secure the medicine containers 11. The frame-structured fixing cavities are custom-made based on the external dimensions of the medicine containers 11, with each cavity corresponding to a specific container 11 for easy and quick placement. U-shaped clips, adjustable clamps, rubber buffer rings, and other structures can also be used to prevent the medicine containers 11 from sliding or tipping over during the drug administration experiment.

[0047] For example, the pumping assembly 2 includes a drug pump 21, a drug inlet pipe 22, and a drug outlet pipe 23.

[0048] The medicine pump 21 can be a small centrifugal pump. The medicine pump 21 is connected to a power source and is driven by the power source to operate. One end of the medicine inlet pipe 22 is connected to the inlet of the medicine pump 21, and the other end is connected to the medicine outlet 12 of the medicine container 11 at the bottom of the medicine container assembly 1. One end of the medicine outlet pipe 23 is connected to the outlet of the medicine pump 21, and the other end extends into the medicine container 11 at the top of the medicine container assembly 1.

[0049] In practical applications, since each set of drug-containing components 1 requires the experimental reagent to circulate, dripping of the experimental reagent during the flow process can cause an oxygenation effect, thus affecting the accuracy of the drug administration experiment. Therefore, in one specific embodiment, the dispensing pipe 23 extends to one end of the top drug-containing container 11 of the drug-containing component 1, located below the highest liquid level of the experimental reagent contained in the container 11, to prevent the experimental reagent dripping and causing an oxygenation effect. If the experimental reagent drips and causes oxygenation, it may affect the consistency of experimental results in different drug-containing containers 11. This structure prevents the liquid from dripping onto the liquid surface, avoids disturbance and bubbles caused by free fall of liquid, thereby reducing oxygen dissolution in the water, improving the constancy and repeatability of experimental conditions, and ensuring more accurate statistical analysis of the drug administration effect.

[0050] Furthermore, the pumping assembly 2 also includes a first connecting pipe 24 and a second connecting pipe 25. One end of the first connecting pipe 24 is connected to the outlet 12 of the medicine container 11 at the top of the medicine container assembly 1, and the other end extends into the medicine container 11 at the bottom of the medicine container assembly 1, and is located below the highest liquid level of the experimental reagent contained in the medicine container 11. The first connecting pipe 24 can also prevent the oxygenation effect. Driven by the circulation of the medicine pump 21, the liquid in the multi-layer tank can flow vertically from top to bottom to form a loop.

[0051] The second connecting pipe 25 is used to connect medicine containers 11 at the same horizontal level in the same group of medicine containers 1. The second connecting pipe 25 establishes a connection between medicine containers 11 at the same level (horizontal level) to keep the concentration and level of the medicine solution at the same level consistent; the second connecting pipe 25 can be set in the middle or bottom of the side wall of the medicine container 11; the balance is formed by the pressure of the liquid itself.

[0052] Furthermore, the pumping assembly 2 also includes a regulating valve 26, which is mounted on the drug outlet pipe 23. The regulating valve 26 can be a manual valve, such as a manual ball valve or a knob-type needle valve. The regulating valve 26 can adjust the output flow rate or pressure of the drug pump 21 to prevent the experimental reagent from splashing or disturbing due to excessive pump speed; thereby achieving periodic intermittent circulation or constant microflow.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
