Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of aquatic incubation and breeding, especially relates to an artificial propagation device for garra rufa. BACKGROUND

[0002] Garra rufa, also known as "fish doctor", is a cyprinid fish originally from Turkey, Syria and other places. Because of its unique habit of liking to peck at the dead skin and other keratin on the surface of human skin, it has been widely used in the hot spring fish therapy industry, and the market demand continues to grow.

[0003] However, the natural reproduction of garra rufa faces many limiting factors. In its natural environment, the reproduction process is restricted by complex ecological conditions, including specific water temperature, water quality, water flow and changes in food resources during the breeding season. With the wild population being heavily fished for commercial use, its natural resources are gradually decreasing, and relying solely on natural reproduction has been difficult to meet the growing market demand.

[0004] Artificial reproduction has become a key way to solve the supply problem of garra rufa. However, the existing fish artificial reproduction technology and device has many shortcomings when applied to garra rufa. Traditional fish breeding ponds or aquariums are not accurate enough in simulating the natural breeding environment of garra rufa. For example, garra rufa has high requirements for water flow speed and water quality stability, and ordinary devices are difficult to accurately control the water flow, resulting in low fertilization rate of fish eggs. Moreover, during the breeding stage of parent fish, there is a lack of facilities specially designed for the habits of garra rufa, which can easily cause stress reactions in parent fish, affecting their gonadal development and reproductive performance.

[0005] In addition, garra rufa has special requirements for spawning substrate during the breeding process, which requires specific materials and shapes to induce its spawning behavior. However, most existing devices do not fully consider this point, making the spawning willingness of parent fish not strong. At the same time, during the fish egg incubation stage, the control of environmental factors such as water flow and dissolved oxygen is not fine enough, which can easily cause abnormal development of fish eggs or low hatching rate.

[0006] In summary, in order to effectively improve the artificial reproduction efficiency and success rate of garra rufa, it is urgent to develop an artificial reproduction device specially designed for the breeding characteristics of garra rufa to fill the gap in existing technology and promote the sustainable development of garra rufa breeding industry.

The spray mechanism 9 is activated, and the water flow rate and temperature of the spray nozzle 92 are adjusted as needed to maintain the water temperature and dissolved oxygen content in the spawning tank 1 within a range suitable for the reproduction of the garrulella rubripes. The broodstock, stimulated by the cobblestone 4 underwater environment and the spray, reproduce, and the eggs are released into the hatching tank 2 through the oviduct 5.

[0050] After the eggs enter the hatching tank 2, the filter mechanism filters the eggs to prevent them from flowing out. The water level and dissolved oxygen content in the hatching tank 2 are controlled by adjusting the height of the overflow pipe 6 and the regulating valve 1204 on the connecting pipe 1203. The water level is kept a certain distance below the top of the overflow pipe 6, and the dissolved oxygen content is maintained at a dissolved oxygen range suitable for hatching. During the incubation process, the filter screen 102 of the filter mechanism is regularly checked and cleaned or replaced in time if any blockage is found.

[0051] Once the fry have hatched and reached a certain size, the control valve 8 on the fry exit pipe 7 is opened, and the fry flow into the fry collection pond 3. During the fry collection process, the water flow rate must be carefully controlled to avoid damage to the fry. The fry collection pond 3 should be prepared in advance with a suitable water environment for fry growth, such as appropriate water temperature, water quality, and dissolved oxygen content, to ensure a smooth transition to the subsequent breeding stage.
