Description

Technical Field

[0001] This utility model belongs to the field of aquaculture technology, and in particular relates to a compound probiotic slow-release device for a spotted loach breeding pond. Background Technology

[0002] The spotted catfish is a fish belonging to the family Bagridae and the genus Hemibarbus. It is also known as the spotted catfish or sesame catfish. Spotted catfish breeding ponds are facilities specifically designed for the artificial breeding of spotted catfish. They need to be designed according to their ecological habits and have both resource protection and commercial breeding functions. Spotted catfish breeding ponds are generally earthen ponds for large-scale breeding. A 20-30cm thick layer of sand and gravel needs to be laid at the bottom of the pond to simulate the natural bottom. The pond walls are reinforced with concrete to prevent leakage.

[0003] In the process of raising spotted loach, in order to improve water quality and bottom environment and promote the healthy growth of spotted loach, compound probiotics are generally introduced. The introduced compound probiotics, such as Bacillus and lactic acid bacteria, can efficiently degrade organic matter such as uneaten feed and feces at the bottom of the pond, reduce the accumulation of harmful substances such as ammonia nitrogen and hydrogen sulfide, and maintain water transparency and dissolved oxygen stability. The digestive enzymes secreted by probiotics, such as protease and lipase, can enhance the absorption of feed nutrients by spotted loach, reduce the feed conversion ratio, and accelerate weight gain. The traditional method of introducing probiotics is generally to directly sprinkle them manually. This method has problems such as rapid loss of bacterial agents, short duration of action, and uneven distribution. In order to solve the inconvenience of manual introduction, slow-release devices are now widely used in the market for introducing probiotics. However, existing slow-release devices mostly release probiotics statically, and cannot adjust the release rate according to the water environment, such as pH and temperature. Spotted fish farming has high requirements for water quality, especially the control of ammonia nitrogen and nitrite, and conventional feeding methods are difficult to maintain stability in the long term. Utility Model Content

[0004] The purpose of this invention is to provide a compound probiotic slow-release device for a spotted loach breeding pond, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A compound probiotic slow-release device for a spotted catfish breeding pond includes a buoyancy adjustment mechanism. The bottom end of the buoyancy adjustment mechanism is connected to a probiotic slow-release mechanism. The probiotic slow-release mechanism includes a stainless steel mesh cover. A connecting rod is fixedly connected to the top end of the stainless steel mesh cover, and a ceramic ball is fixedly connected to the bottom end of the connecting rod. The ceramic ball has pores around its interior. The pores contain a first probiotic microcapsule and a second probiotic microcapsule. A pH-responsive membrane is attached to the inner wall of the first probiotic microcapsule, and a temperature-sensitive gel layer is attached to the inner wall of the second probiotic microcapsule. Both the pH-responsive membrane and the temperature-sensitive gel layer are filled with probiotics.

[0007] Furthermore, the stainless steel mesh cover and ceramic ball are fixedly connected to the connecting rod, and the ceramic ball is fixedly connected to the bottom end of the buoyancy adjustment mechanism through the connecting rod.

[0008] Furthermore, the stainless steel mesh cover is spherically fitted around the outer periphery of the ceramic sphere, and the pores are evenly distributed around the inner periphery of the ceramic sphere.

[0009] Furthermore, the first and second probiotic microcapsules are uniformly filled along the interior of the pores, and the outer walls of the first and second probiotic microcapsules are biodegradable polymer matrices.

[0010] Furthermore, the pH-responsive membrane and the temperature-sensitive gel layer are uniformly attached to the inner walls of the first and second probiotic microcapsules, respectively, and the inner walls of both the pH-responsive membrane and the temperature-sensitive gel layer are coated with probiotic agents.

[0011] Furthermore, the buoyancy adjustment mechanism includes a buoyancy ball, a rubber ring fixed to the top of the buoyancy ball, a silicone tube sleeved on the inner wall of the rubber ring, an air pump connected to the top of the silicone tube, an air bladder connected to the bottom of the silicone tube, and drainage holes opened on both sides of the bottom of the buoyancy ball.

[0012] Furthermore, the airbag is connected to the air pump via a silicone tube, and after the airbag expands, it fills the inner wall of the buoyancy ball evenly.

[0013] The advantages of this utility model compared to the prior art are as follows:

[0014] 1. The stainless steel mesh cover of this utility model can provide protection for the internal release structure. The ceramic ball and pores fixed at the bottom of the connecting rod form a porous bioceramic structure, which can uniformly load the first probiotic microcapsule and the second probiotic microcapsule. Combined with the biodegradable polymer matrix material on the outer wall of the first probiotic microcapsule and the second probiotic microcapsule, the slow degradation maintains a stable sustained release process, reduces the loss of internal probiotics and enhances the duration of action.

[0015] 2. The first and second probiotic microcapsules of this invention use a pH-responsive membrane and a temperature-sensitive gel layer as internal filling layers, respectively. The probiotics inside the microcapsules are encapsulated by the pH-responsive membrane and the temperature-sensitive gel layer. The pH-responsive membrane can accelerate the release of probiotics when the pH of the water in the aquaculture pond is abnormal, while the temperature-sensitive gel layer can increase the release amount when the water temperature rises to cope with the accelerated metabolism of microorganisms, thereby prolonging the survival time of probiotics and achieving the purpose of adaptively regulating the release according to different environmental conditions in the aquaculture pond.

[0016] 3. This utility model uses a buoyancy ball in the aquaculture pond as the main structural carrier. The buoyancy ball is connected to the probiotic slow-release mechanism by a connecting rod at the bottom of the buoyancy ball. The buoyancy ball can be connected to the air bladder and silicone tube inside the buoyancy ball and the air pump. The water inside the buoyancy ball is discharged by the expansion of the air bladder, forming a process of adjusting the buoyancy. Thus, the slow-release device can be installed and used to meet different water depth requirements. Attached Figure Description

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of this utility model, and these aspects can be achieved even without these specific details.

[0024] like Figure 1-5As shown, a compound probiotic slow-release device for a spotted catfish breeding pond includes a buoyancy adjustment mechanism 1. The bottom end of the buoyancy adjustment mechanism 1 is connected to a probiotic slow-release mechanism 2. The buoyancy adjustment mechanism 1 includes a buoyancy ball 101. A rubber ring 102 is fixed to the top of the buoyancy ball 101. A silicone tube 103 is sleeved on the inner wall of the rubber ring 102. An air pump 104 is connected to the top of the silicone tube 103. An air bag 105 is connected to the bottom end of the silicone tube 103. Drainage holes 106 are opened on both sides of the bottom end of the buoyancy ball 101.

[0025] To provide controllable slow-release depth of the entire device within the aquaculture pond, such as Figure 1-2 As shown, this compound probiotic slow-release device uses a buoyancy ball 101 in the aquaculture pond as the main structural carrier. The buoyancy ball 101 is connected to the probiotic slow-release mechanism 2 by a connecting rod 202 at the bottom of the buoyancy ball 101. The buoyancy ball 101 can be connected to the air pump 104 through the internal air bladder 105 and silicone tube 103. The internal water is discharged by the expansion of the air bladder 105 inside the buoyancy ball 101, forming a process of adjusting the buoyancy. This allows the slow-release device to be installed and used to meet different water depth requirements.

[0026] like Figure 3-5 As shown, the probiotic sustained-release mechanism 2 includes a stainless steel mesh cover 201. A connecting rod 202 is fixedly connected to the top of the stainless steel mesh cover 201, and a ceramic ball 203 is fixedly connected to the bottom of the connecting rod 202. The ceramic ball 203 has pores 204 around its interior. The pores 204 are loaded with a first probiotic microcapsule 205 and a second probiotic microcapsule 206. A pH-responsive membrane 207 is attached to the inner wall of the first probiotic microcapsule 205, and a temperature-sensitive gel layer 208 is attached to the inner wall of the second probiotic microcapsule 206. Both the pH-responsive membrane 207 and the temperature-sensitive gel layer 208 are filled with probiotics 209.

[0027] To provide a stable slow-release delivery process in aquaculture pond environments, such as Figure 3-5 As shown, the stainless steel mesh cover 201 of this composite probiotic sustained-release device can protect the internal release structure. The ceramic ball 203 fixed at the bottom of the connecting rod 202 and the pores 204 form a porous bioceramic structure, which can evenly load the first probiotic microcapsule 205 and the second probiotic microcapsule 206. With the biodegradable polymer matrix material on the outer wall of the first probiotic microcapsule 205 and the second probiotic microcapsule 206, the slow degradation maintains a stable sustained-release process, reduces the loss of internal probiotics 209 and increases the action time.

[0028] The first probiotic microcapsule 205 and the second probiotic microcapsule 206 respectively use a pH-responsive membrane 207 and a temperature-sensitive gel layer 208 as internal filling layers. The probiotics 209 inside the microcapsule are encapsulated by the pH-responsive membrane 207 and the temperature-sensitive gel layer 208. The pH-responsive membrane 207 can accelerate the release and regulate the probiotics 209 when the pH of the water in the aquaculture pond is abnormal, while the temperature-sensitive gel layer 208 can increase the release amount when the water temperature rises to cope with the accelerated metabolism of microorganisms, thereby prolonging the survival time of probiotics and achieving the purpose of adaptively regulating the release according to different environmental conditions in the aquaculture pond.

[0029] In summary, the structure of this composite probiotic slow-release device allows the user to first place the buoyancy ball 101 and the probiotic slow-release mechanism 2 at the bottom into the aquaculture tank. The silicone tube 103 extending from the top of the buoyancy ball 101 is connected to the air pump 104 outside the aquaculture tank. By operating the air pump 104 to inflate the device, the air bladder 105 inside the buoyancy ball 101 is filled. At this time, the water inside the buoyancy ball 101 is squeezed by the filled air bladder 105 and discharged through the drain holes 106 on both sides of the bottom. The buoyancy ball 101 then rises with buoyancy, completing the depth adjustment in the aquaculture tank. Subsequently, the water is discharged through the pores 204 of the ceramic ball 203. The first probiotic microcapsule 205 and the second probiotic microcapsule 206 loaded inside are subjected to a slow-release process. The outer walls of the first probiotic microcapsule 205 and the second probiotic microcapsule 206 are both biodegradable polymer matrices, which degrade over time and are thus slowly released into the water. When the pH of the water is abnormal, such as in the range of <6.5 or >8.5, the pH-responsive membrane 207 of the first probiotic microcapsule 205 accelerates the release of regulatory bacteria. When the water temperature rises, such as >28℃, it is released in conjunction with the temperature-sensitive gel layer 208, further increasing the release of probiotics 209 to cope with the accelerated microbial metabolism, thus completing the adaptive regulation and slow-release process.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
