Description

Technical Field

[0001] The utility model relates to the technical field of ecological breeding of special fish, in particular to an ecological breeding device for rock climbing catfish. Background Art

[0002] The stone crawler is a fish belonging to the genus Cercoidea, family Cercoidea, and order Siluriformes. This genus consists of two species: the yellow stone crawler and the blue stone crawler. The yellow stone crawler, commonly known as Huangshiclimbing or Shiclimbing, is found in the Jinsha River system in Qinghai, Sichuan, Yunnan, and Tibet. Within Sichuan, it is found in rivers in the surrounding mountainous areas and western mountainous regions. The blue stone crawler, commonly known as Qingshiclimbing or Shiclimbing, is found only in the Qingyi, Min, Jinsha, Yalong, and upper Dadu rivers in Sichuan. It is endemic to the upper reaches of the Yangtze River and is listed as a key protected wildlife in Sichuan Province. The stone crawler has delicious meat, rich in protein and fat, and is highly valued in the market. However, due to overfishing of barracuda and other factors, natural catches have been declining.

[0003] Many domestic aquaculture organizations are currently attempting to overcome the challenges of artificially domesticating catfish. Traditional methods employ dams or ponds, typically covering three to five mu (approximately 1.5 to 2.5 acres), with 50-70 broodstock per acre. These broodstock are supplemented with a small number of silver and bighead carp. This method of rearing catfish requires a large amount of feed, is costly, and has a low survival rate (catfish are prone to mortality between January and June). Furthermore, the fish are not observed to eat independently, thus defeating the purpose of artificially domesticating catfish. Utility Model Content

[0021] Example 1

[0022] Reference Figure 1 , Figure 2 The ecological breeding device of the stone climbing catfish of the present invention includes a cylinder body 2, a water inlet assembly 1 and a drainage assembly 3. The cylinder body 2 adopts a cylindrical structure, such as a circular fiberglass fish tank, which is made of fiberglass, φ=2000mm, H=1000mm, and the breeding water level is controlled at 100mm. The water inlet assembly 1 enters the cylinder body 2 from the upper part of the cylinder body 2 and extends to the bottom of the cylinder body 2 to take in water. It is composed of a valve, a 32mm PE pipe, and a 32mm elbow, and is connected to the bottom of the cylinder body 2. The water outlet 11 of the water inlet assembly 1 is located at the bottom of the cylinder body 2 and close to the edge of the side wall of the cylinder body 2. The water outlet 11 is arranged tangentially along the coaxial circumference of the cylinder body 2. The water output can be controlled by the valve, and the water flowing out along the tangential direction can form a circulation in the circular structure of the cylinder body 2, thereby simulating the river flow rate. The drainage component 3 is connected to the middle of the bottom of the cylinder body 2 for drainage. The drainage component 3 is composed of a 90mm PE pipe and a valve. The water flow entering from the water inlet component 1 circulates in the cylinder body 2 and eventually flows into the drainage component 3 from the middle of the bottom of the cylinder body 2 and flows away from the drainage component 3.

[0023] A sunshade net 6 is provided on the top of the cylinder body 2. The sunshade net 6 adopts an 88-needle sunshade net 6. The sunshade area is roughly less than half of the top area of the cylinder body 2 and larger than one-third of the top area of the cylinder body 2. For example, as shown in the figure, on the basis of the half-semicircle structure, the middle part is formed by an arc depression, thereby simulating the dim scene in the wild shallow water environment.

[0024] The bottom of the cylinder 2 is surrounded by a pebble layer 4, which is arranged around the connection of the drainage assembly 3. It uses 3-6 smooth pebbles, each measuring 80-160 mm. In the middle of the pebble layer 4 is the connection around the drainage assembly 3, where an anti-escape component 5 is installed, such as a filter or floor drain, to allow water to flow through while preventing stones from crawling through.

[0025] The ecological breeding device for the rock climbing catfish of this embodiment is provided with a water inlet component 1 that sprays in a tangential direction, so that a circulation can be formed in the cylindrical cylinder 2, simulating the water flow environment in the wild environment. At the same time, a sunshade net 6 is provided on the top of the cylinder 2 to simulate the dim scene in the shallow water environment in the wild, and pebbles are laid at the bottom of the cylinder 2, so that the entire breeding device forms a small ecological environment, effectively improving the survival rate of the rock climbing catfish.

[0026] Example 2

[0027] Reference Figure 3-Figure 5 This embodiment is a further improvement made on the basis of embodiment 1. The difference is that the water inlet assembly 1 in the cylinder body 2 is further provided with a plurality of auxiliary water outlets 12. The auxiliary water outlets 12 are arranged from bottom to top, and the diameter of the water outlet 11 gradually decreases. By setting auxiliary drainage outlets of different diameters, it is possible to achieve different flow rates of water at different heights, so that different habitual stone climbing catfish can be used. At the same time, the angle between the auxiliary water outlets 12 and the circumferential direction gradually increases from bottom to top, that is, the auxiliary water outlet 12 at the lower end basically flows along the tangential direction, while the upper one slowly changes and flows toward the middle, thus providing different water flow directions, but the overall flow is still circular. Therefore, the upper aperture is small, which has an impact on the water flow, but it is not enough to change the general trend.

[0028] In order to increase the circulation effect, the water inlet assembly 1 includes a first water inlet pipe and a second water inlet pipe extending into the cylinder body 2. The first water inlet pipe is provided with a plurality of auxiliary water outlets 12 and a water outlet 11 at the end of the position pipe. The second water inlet pipe is provided with a plurality of auxiliary water outlets 12. The first water inlet pipe and the second water inlet pipe are respectively located on both sides of the inside of the cylinder body 2, and the direction of the auxiliary water outlet 12 of the first water inlet pipe and the direction of the auxiliary water outlet 12 of the second water inlet pipe are centrally symmetrically distributed.

[0029] In order to prevent the water coming out of the water outlet 11 from flowing directly into the drainage assembly 3, a spiral guide groove 7 is provided at the bottom of the cylinder body 2. The height of the bolt guide groove is higher than the position of the water outlet 11. The water coming out will be guided along the spiral guide groove 7 to form a circulation, and the water flow gradually gathers towards the center.
