Description

Technical Field

[0001] This invention relates to the field of giant spiny loach farming technology, specifically a method for high-density giant spiny loach farming. Background Technology

[0002] The giant spiny loach (Scoprinus spp.) is a fish belonging to the family Cobitidae in the order Perciformes. Other names include spiny loach, stone spiny loach, coarse spiny loach, chili fish, and knife-spear fish. It has an elongated, laterally compressed body. The head is laterally compressed; the snout is long and pointed; the mouth is small with a straight cleft; the upper and lower jaws have multiple rows of fine, sharp teeth; both the head and body are densely covered with small, cycloid scales, with a distinct lateral line containing over 300 scales; the dorsal fin originates above the middle of the pectoral fin; the anal fin connects to the caudal fin at its posterior end; the caudal fin is nearly rounded. Due to overfishing and river pollution, the wild population of giant spiny loach has been severely damaged, and it is listed as a key protected wild aquatic animal in Guangdong, Fujian, and Guizhou provinces. In the early 21st century, the Pearl River Fisheries Research Institute of the Chinese Academy of Fishery Sciences and the Guangxi Zhuang Autonomous Region Fisheries Research Institute, among others, reported successful artificial breeding and aquaculture.

[0003] High-density farming of spiny loaches typically involves stocking fingerlings over 5 cm in length between May and June each year. After 8-10 months of rearing, the adult fish reach an average weight of over 200 grams and are ready for harvest. During this period, regular, scheduled feeding is required, a process that is not only tedious but also necessitates adjusting the feed based on the loaches' growth. However, visually observing the loaches' body shape to change feed cannot guarantee that the new feed is suitable for their growth stage. Inaccurate feeding can lead to uneven growth and significant individual differences, which is detrimental to high-density farming. Furthermore, the feed is often pre-processed pellets, which are hard and difficult for the loaches to absorb. These pellets are also prone to deterioration during transportation or storage, severely impacting high-density loach farming. Therefore, a new method for high-density spiny loach farming is needed.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

The breeding device automatically adjusts the feed size by moving the transmission bent rod, thereby achieving the purpose of matching the feed pellet size with the current size of the giant spiny loach.

[0023] By setting up a tension sensor to analyze the drag force of the giant spiny loach, the drag force is reflected to a micro motor, which drives the transmission screw to rotate. The rotation of the transmission screw causes the extrusion block to descend. The descent of the extrusion block controls the movement of the straight rod adjustment block and the curved rod adjustment block. The breeding device uses the tension sensor to analyze the drag force of the giant spiny loach to control the movement of the straight rod adjustment block and the curved rod adjustment block, and adjusts the composition and size of the feed particles in a timely manner to reduce feeding errors.

[0024] The aquaculture device adjusts the motion power of the rotary cutter and the arc-shaped discharge plate by adjusting the tension of the rotary cutting conveyor belt and the discharge conveyor belt. It also changes the feeding method according to the body size of the giant spiny loach at different stages, thereby improving the overall survival rate of the giant spiny loach and promoting its balanced growth.

[0043] Because feeding spiny loaches requires manual, timed, and fixed-location feeding, which is labor-intensive and involves complicated procedures, and requires observing the growth of the loaches to change the feed, visually adjusting the feed based on their body shape cannot guarantee that the new feed is suitable for their growth. Furthermore, the feed is mostly pre-processed pellets, which are hard and difficult for the loaches to absorb. During transportation or storage, the feed is prone to becoming damp and deteriorating due to accumulation, and these deteriorated pellets are difficult for workers to observe. Feeding such feed not only impacts water resources but also causes irreversible damage to the high-density spiny loaches. Therefore, this invention provides a technical solution: a method for high-density spiny loach farming, comprising the following steps:

[0044] Step 1: Place the aquaculture equipment on the bank of the aquaculture pond;

[0045] Step 2: Prepare the feed on-site according to the feeding time;

[0046] Step 3: Adjust the feed composition ratio in a timely manner according to the growth of the giant spiny loach;

[0047] Step 4: Adjust the shape and size of the feed pellets according to the growth of the giant spiny loach;

[0048] Step 5: Expand the feeding area according to the growth of the giant spiny loach.

[0049] A support panel 4 is fixedly installed inside the outer casing 1. The surface of the support panel 4 is marked with a fold line 17. An adjustment component 100 for adjusting the movement of each component is provided below the support panel 4. A raw material preparation component 200 for adjusting the feed composition ratio is provided above the support panel 4. A feed forming component 300 for adjusting the feed particle diameter is provided below the raw material preparation component 200. A conveying control component 400 for adjusting the feed length and feeding area is provided below the feed forming component 300 and above the adjustment component 100.

[0050] To improve the practicality of the aquaculture equipment, the adjustment assembly 100 includes a straight rod adjustment block 101, a transmission straight rod 103, a limit rod 104, a bent rod adjustment block 105, and a transmission bent rod 107. The transmission straight rod 103 controls the rotation of the rotating shaft 201 by sliding the straight rod adjustment block 101; the transmission bent rod 107 controls the rotation of the planetary gear 302 by sliding the bent rod adjustment block 105; and the limit rod 104 controls the tensioning of the rotary cutting conveyor belt 402 by moving the transmission straight rod 103.

[0051] Furthermore, a straight rod auxiliary spring 102 is fixedly connected to the right surface of the straight rod adjusting block 101, and the straight rod adjusting block 101 is fixedly connected to the transmission straight rod 103. A limit rod 104 is fixedly connected to the surface of the transmission straight rod 103; a bending rod auxiliary spring 106 is fixedly connected to the left surface of the bending rod adjusting block 105, and the bending rod adjusting block 105 is fixedly connected to the transmission bending rod 107.

[0052] To control the discharge of feed raw materials and automatically change the feed composition ratio, a rotating shaft 201 is rotatably connected to the outer shell 1. A sliding rod 202 is fixedly connected to the lower surface of the rotating shaft 201, and an extrusion rod 203 is fixedly connected to the upper surface of the rotating shaft 201. A mating block 204 is movably arranged on the left side of the extrusion rod 203. One end of the mating block 204 is rotatably connected to the outer shell 1, and the other end of the mating block 204 is movably connected to a left blocking plate 205. A blocking block 207 is fixedly connected to the upper surface of the left blocking plate 205. An adjusting gear 209 is meshed with the front end of the left blocking plate 205, and a right blocking plate 208 is meshed with the lower part of the adjusting gear 209. The raw material mixing component 200 is symmetrically arranged along a fold line 17.

[0053] To automatically adjust the feed specifications according to the growth of the giant spiny loach, the feed preparation component 300 includes a protective shell 301 and a cover plate 303. The protective shell 301 is rotatably connected to a planetary gear 302, which meshes with a transmission rod 107. An adjustment part 304 is meshed with the inner surface of the planetary gear 302. A limit disk 309 is rotatably connected to the lower surface of the adjustment part 304, and a limit shaft 306 is rotatably connected to the upper surface of the limit disk 309. A triangular adjusting block 307 is fixedly connected to the surface. Several limiting grooves 308 are opened on the inner surface of the adjusting part 304. The limiting grooves 308 are slidably connected to the limiting shaft 306. The cover plate 303 is rotatably connected to the planetary gear 302. A diverting block 305 is fixedly connected to the upper surface of the cover plate 303. The diverting block 305 diverts the feed extruded by the feed preparation machine 3 to prevent it from accumulating inside the protective shell 301 and causing equipment damage. The feed making component 300 is symmetrically arranged with a fold line 17.

[0054] To adjust the feed feeding speed and range, the conveying control component 400 includes a servo motor 401. Below the servo motor 401, a rotary cutting conveyor belt 402 and a discharge conveyor belt 404 are engaged and driven. On the surface of the rotary cutting conveyor belt 402, a rotary cutting blade 403 is engaged and driven. The rotary cutting blade 403 is located below the protective shell 301. The discharge conveyor belt 404 engages and drives a limiting shaft 405. Below the limiting shaft 405, an arc-shaped discharge plate 406 is fixedly connected. The conveying control component 400 is symmetrically arranged along a fold line 17.

[0055] To better observe the growth of the giant spiny loach, a squeezing block 7 is slidably arranged in the middle of the straight rod adjusting block 101 and the curved rod adjusting block 105. Limiting rods 8 are rotatably arranged on the front and rear sides of the squeezing block 7. A spring is arranged between the limiting rods 8 and the squeezing block 7 to enhance the stability between the limiting rods 8 and the straight rod adjusting block 101 and the curved rod adjusting block 105. A transmission screw 9 is engaged in the middle of the squeezing block 7. A micro motor 10 is fixedly connected to the lower part of the transmission screw 9. The micro motor 10 is fixedly connected to the outer shell 1. A tension sensor 11 is fixedly arranged below the micro motor 10. A pull rope 12 is movably arranged below the tension sensor 11. A feed bait 13 is fixedly connected to the lower part of the pull rope 12. A conveying pipe 16 is fixedly connected to the surface of the pull rope 12. A compression pipe 15 is fixedly connected to the upper part of the conveying pipe 16.

[0056] A storage cover 2 is fixedly installed on the upper surface of the outer shell 1. A feeding trough 14 is provided inside the outer shell 1 and above the material blocking block 207. A fixing plate 210 is provided inside the outer shell 1 and below the feeding trough 14. The left material blocking plate 205 and the right material blocking plate 208 slide inside the fixing plate 210. A feed preparation machine 3 is fixedly installed inside the outer shell 1. The feed preparation machine 3 is fixedly connected to the upper surface of the protective shell 301. A cooling pipe 5 is provided below the feed preparation machine 3. The cooling pipe 5 can cool the feed pellets in time. The cooling pipe 5 is movably connected to the lower surface of the protective shell 301. A feeding port 6 is fixedly connected to the lower surface of the cooling pipe 5.

[0057] The limiting shaft 405 is rotatably connected to the feeding port 6, and the arc-shaped discharge plate 406 is placed inside the feeding port 6; the rotary cutter 403 is rotatably connected to the cooling pipe 5, and the rotary cutter 403 is placed between the upper surface of the cooling pipe 5 and the lower surface of the protective shell 301.

[0058] Working principle: The breeding device is fixed on the bank of the breeding farm, with the bottom surface of the outer shell 1 slightly in contact with the water surface. The pull rope 12 and the feed bait 13 are completely immersed in the water. Various raw materials are placed on the upper part of the outer shell 1, and fish attractant is applied to the surface of the feed bait 13. Because the pull rope 12 is made of transparent nylon filaments, the feed bait 13 sways continuously with the wind and waves in the water, thereby simulating insects such as water fleas, enhancing the feeding desire of the spiny loach, increasing the frequency of the spiny loach dragging the feed bait 13, and ensuring that the tension sensor 11 can obtain a large amount of data for various analyses.

[0059] The larger the individual spiny loach, the greater the drag force on the feed lure 13. The pulling force generated during dragging is summarized every 10 days and the average value is taken. The average value is captured and then reflected to the Internet of Things terminal to track the working status of the micro motor 10. The working of the micro motor 10 is used to rotate and adjust the transmission screw 9. The rotation of the transmission screw 9 adjusts the downward movement distance of the extrusion block 7. The movement of the extrusion block 7 controls the sliding distance of the straight rod adjusting block 101 and the curved rod adjusting block 105.

[0060] When the straight rod adjusting block 101 slides inside the outer shell 1, the straight rod adjusting block 101 drives the transmission straight rod 103 to move synchronously. The transmission straight rod 103 passes through the slide bar 202, so the extrusion rod 203 rotates around the rotating shaft 201. The rotation of the extrusion rod 203 extrudes and controls the swing of the mating block 204. The swing of the mating block 204 pushes the left blocking plate 205 to slide to the left. Under the action of the adjusting gear 209, the right blocking plate 208 slides relative to the left blocking plate 205, thereby widening the gap between the right blocking plate 208 and the left blocking plate 205. At this time, the discharge volume of each raw material is uniform and increases synchronously. Then, the discharge diameter of each raw material is adjusted and blocked by the blocking block 207, thereby automatically adjusting the ratio between the components of the feed.

[0061] Furthermore, as demonstrated in the 9th issue of "China Feed" in 2018, the optimal ratio of protein, methionine, and fat in the formula feed for juvenile spiny loach is 50%, 1.7%, and 8%, respectively. However, spiny loach have different feed requirements at different growth stages, therefore the feed formulation needs to be adjusted accordingly. For example, during the tadpole stage, the intake of protein and vitamins needs to be increased, while during the mature stage, the intake of protein and fatty acids needs to be increased. Therefore, the nutritional composition of the feed needs to be improved in a timely manner according to the body size of the spiny loach at different stages.

[0062] When the bending rod adjusting block 105 slides, the transmission bending rod 107 is fixedly connected to the bending rod adjusting block 105, and the transmission bending rod 107 is meshed with the planetary gear 302. When the transmission bending rod 107 slides, it drives the planetary gear 302 to rotate. The inner ring of the planetary gear 302 drives the adjusting part 304 to mesh and rotate. The limiting shaft 306 is rotatably connected to the limiting disk 309. The limiting shaft 306 slides on the surface of the limiting groove 308 through the rotation of the adjusting part 304. At this time, the limiting shaft 306 rotates slightly through the guide of the limiting groove 308, thereby expanding the opening between several sets of triangular adjusting blocks 307, so that the diameter of the extruded feed particles is increased, which makes it easier for the large spiny loach to forage during its growth period.

[0063] The servo motor 401 engages with the rotary cutting conveyor belt 402, driving the rotary cutting blade 403 to rotate and cut the extruded feed into uniformly sized polygonal cuboids. This polygonal cuboid feed is suitable for high-density aquaculture of large spiny loach. As summarized in Chinese Patent CN 1058378C, the advantages of strip-shaped feed are: "When a very short piece of fish feed is cut from a continuous strip formed by the method disclosed in this invention and processed into a flat shape that is very thin along its extrusion direction, even very small fish can swallow this pellet feed. However, if the extrusion direction is opposite, such small fish cannot swallow the pellets. The flat, elongated cross-section of the continuous strip produced by the method disclosed in this invention can be slightly larger than existing pellet feeds used to feed small fish. On the other hand, the pellet feed made according to this invention, with the same cross-sectional size, is also suitable for feeding larger fish. Therefore, the advantage of this invention is that several different sizes of fish feed can be made from the same continuous strip. That is, a strip with one cross-sectional size can be used to manufacture pellet feed of various sizes."

[0064] The length of the feed produced by the aquaculture device is controlled by the movement speed of the rotary cutter 403. When the straight rod adjusting block 101 slides, the tension on the surface of the rotary cutting conveyor belt 402 loosens from the tight side, and the rotation speed of the rotary cutter 403 gradually decreases. At this time, the length of the feed particles produced by the aquaculture device is correspondingly extended. Therefore, under the premise that the feed diameter can be automatically adjusted according to the growth changes of the giant spiny loach, by extending the length of the feed, it is possible to feed the giant spiny loach that grows slowly or is malnourished and is small in size, and also to ensure that the giant spiny loach that grows normally can forage normally.

[0065] The breeding device drives the limiting shaft 405 to rotate through the meshing transmission of the servo motor 401 and the feed conveyor belt 404. The limiting shaft 405 then drives the arc-shaped feed plate 406 to rotate synchronously, feeding the feed pellets cooled by the cooling pipe 5. The arc-shaped feed plate 406 is made of soft silicone, which will not affect the feed when the feed pellets are tapped and fed.

[0066] The movement frequency of the arc-shaped feed plate 406 in the aquaculture device is affected by the rotation speed of the feed conveyor belt 404. When the straight rod adjusting block 101 slides, the feed conveyor belt 404 gradually tightens. At this time, the rotation speed of the limiting shaft 405 increases accordingly, thus increasing the feeding frequency of the arc-shaped feed plate 406 and gradually increasing the thrust on the feed particles, allowing the feed to be fed further. Therefore, under the same feeding conditions of a certain number of spiny loaches, the feeding area is changed according to the growth size of the spiny loaches. During the juvenile stage, spiny loaches are small in size and occupy less space when feeding. As the spiny loaches grow, the small feeding space is insufficient for them to concentrate on feeding, leading to excessive concentration and causing oxygen deprivation and death. Therefore, the aquaculture device synchronizes the feeding area according to the size of the spiny loaches to reduce oxygen deprivation and death when they concentrate on feeding and promote balanced growth.

[0067] As the extrusion block 7 moves downward, the compression tube 15 is gradually compressed. The air inside the compression tube 15 is injected into the feed bait 13 through the delivery tube 16 and the pull rope 12, and the feed bait 13 expands accordingly. The size of the feed bait 13 is adjusted in a timely manner according to the growth of the giant spiny loach, thus improving the practicality of the tension sensor 11.

[0068] The aquaculture device discharges the feed raw materials above the fixed plate 210 into the feed preparation machine 3. The feed preparation machine 3 is a small floating fish feed extruder model AKP-40. This invention only automatically adjusts the feed extrusion diameter through the feed making component 300 and automatically adjusts the feed extrusion length through the conveying control component 400. The working principle and feed preparation process of the feed preparation machine 3 remain unchanged.

[0069] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the scope and spirit of the invention, the scope of which is defined by the claims and their equivalents.
