Description

Technical Field

[0001] The present application relates to the field of fish farming, and in particular to a slimming fish farming system and a farming method thereof. Background Art

[0002] Slimming fish is a kind of fish obtained by placing fish in fish ponds and raising them without feed, and then expelling impurities from their bodies. Slimming fish can be conventional freshwater farmed fish species such as grass carp and bighead carp. Slimming fish has better meat texture and taste than the same fish that have not been slimmed down, so it has good economic benefits.

[0003] At present, after a certain period of time of feed-free breeding in the slimming pool, the slimming fish can be salvaged and sold. The existing slimming pool used for slimming fish is rectangular, formed by welding together multiple stainless steel plates. Compared with the mud ponds used for conventional freshwater fish farming, it is less susceptible to factors such as terrain and environment, making it easier to achieve large-scale and unified breeding of slimming fish.

[0004] However, when fishing fish that have completed slimming in existing slimming pools, it is often necessary to first insert partitions into the pool to divide the rectangular pool into several sections, thereby reducing the range of the fish's activity. The fish are then fished from the areas separated by the partitions. In this process, in order to avoid injuring the fish during fishing, thereby affecting economic benefits, fish farmers often use cotton thread fishing nets for fishing, but this also leads to low fishing efficiency. Summary of the Invention

[0005] Firstly, in order to improve the efficiency of catching fish, the present application provides a slimming fish farming system.

[0006] The present application provides a slimming fish farming system that adopts the following technical solutions:

[0007] It includes a slimming pool, a fish driving component and a fishing component. The fishing component includes a fishing cage, a hanger, a lifting motor, a winding roller, a sliding plate and a slide rail. The slide rail is laid on the ground and parallel to the slimming pool. The hanger includes a vertical frame, a horizontal frame and a base. The vertical frame is vertically installed on the base, and the base slides with the slide rail. The horizontal frame is located above the slimming pool and is hinged to the vertical frame. The sliding plate is installed on the horizontal frame and can move along the length of the horizontal frame. The winding roller is installed on the sliding plate. The lifting motor is connected to the winding roller. A rope is wound on the winding roller. One end of the rope is connected to the winding roller, and the other end of the rope is connected to a hook for lifting the fishing cage. The fish driving component is used to drive the fish in the slimming pool to move in the same direction.

[0008] The fish that has been slimmed down in the fish cage can be taken out of the fishing alley by the staff during the whole process, and the staff does not need to enter the slimming pool to salvage the fish, thereby reducing the risk of fish injury and achieving the effect of improving fishing efficiency.

[0009] Optionally, the fishing cage includes a cage body and a cage door, with plug-in parts provided at both ends of the cage door, and plug-in grooves provided at positions corresponding to the plug-in parts on the cage body. The cage door and the cage body are connected by plug-in cooperation, and a limiting part is provided on the top of the cage door, and a flexible roller is provided at the bottom of the cage door. After the cage door and the cage body are plugged in, a gap remains between the flexible roller and the bottom of the cage body.

[0032] The fish in the slimming pool maintain their vital signs by absorbing microorganisms and oxygen in the water. By opening the water replenishment component and the sewage discharge component, the water in the slimming pool is kept in a flowing state, and the sewage discharged by the fish in the slimming pool is discharged at the same time.

[0033] Conduct regular daily inspections to separate abnormal fish from the fish school and take appropriate measures;

[0034] When the breeding time reaches the expected time, the fishing cage is lifted by the lifting motor on the horizontal frame, and the fishing cage is placed in the slimming pool. The sliding cooperation between the base and the slide rail is used to slowly move the fishing cage from one end of the slimming pool to the fish driving assembly, thereby initially reducing the range of activity of the fish school. The fish driving assembly is then started to drive the fish school to swim towards the fishing cage. The fishing cage is closed and lifted by the hook on the lifting motor. The sliding plate is pulled by grabbing the rope on the sliding plate to move the fishing cage to the outside of the slimming pool, thereby completing the capture of the fish school.

[0035] In summary, this application includes at least one of the following beneficial technical effects:

[0036] 1. The fishing cage can be lifted by setting a hanger and hung from the top of the slimming pool to the outside of the slimming pool, so that the staff can catch the fish in the slimming pool and improve the efficiency of the staff in catching fish.

[0037] 2. By setting up fish-driving components, the range of fish movement is restricted, making it easier for the fish cage to catch the fish, thereby indirectly improving the efficiency of fish catching;

[0038] 3. By setting a flexible roller at the bottom of the cage door, when the tail or head of the fish is outside the fishing cage, the fish can break free more easily when squeezed by the cage door, thereby reducing the risk of the fish being squeezed and injured.

[0039] 4. By placing the fish in the slimming pool for feeding without feed, the fish cultured in the slimming pool maintain their vital signs only through the oxygen produced by microorganisms and oxygenation devices, so that the fish in the fish will metabolize the impurities in the body, achieving the purpose of slimming the fish, thereby achieving the effect of making the fish meat more compact and without muddy smell.

The driving member 32 pushes the fish driving net 31 toward the direction close to the fish cage. When the driving work of the fish is completed, the cage door 211 of the fishing cage 21 is plugged into the cage body 212 to prevent the fish in the fishing cage 21 from escaping. The hook is hooked on the rope at the top of the fishing cage 21, and the lifting motor 23 is started to lift the fishing cage 21 from the slimming pool 1. There is no need for the breeders to use cotton rope fishing nets for large-scale fishing, thereby achieving the effect of improving fishing efficiency.

[0062] Example 2:

[0063] Example 2 of the present application discloses a method for breeding slimming fish, the steps of which are as follows:

[0064] Purchase healthy, edible adult freshwater fish with no obvious damage on the surface, disinfect them and transport them to a slimming pool for standby use;

[0065] Turn on the water pump 41 and the oxygenation device 5, check the water temperature in the slimming pool 1, and confirm that the water temperature in the slimming pool 1 is within the range of 21 to 26 degrees Celsius, the nitrite content in the water in the slimming pool 1 is below 0.2 ppm, and the dissolved oxygen content reaches above 5 ppm, then pour the disinfected fish into the slimming pool 1;

[0066] The fish in the slimming pool 1 maintain their vital signs by feeding on microorganisms and absorbing oxygen in the water. By opening the water replenishment component 4 and the sewage discharge component 7, the water in the slimming pool 1 is kept in a flowing state, and at the same time, the sewage discharged by the fish in the slimming pool 1 is discharged into the sewage channel 8.

[0067] Conduct regular daily inspections to separate abnormal fish from the fish school and take appropriate measures;

[0068] When the breeding time reaches the expected time, the fishing cage 21 is lifted by the lifting motor 23 on the horizontal frame 222 and then placed in the slimming pool 1. The sliding cooperation between the base 223 and the slide rail 26 makes the fishing cage 21 slowly approach the fish driving component 3 from one end of the slimming pool 1, initially reducing the range of activity of the fish school, and then start the fish driving component 3, which makes the fish school swim towards the fishing cage 21. The fishing cage 21 is closed and lifted by the hook on the lifting motor 23.
