Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aquaculture, in particular to a micropterus salmoides breeding device and breeding method. BACKGROUND

[0002] Micropterus salmoides prefers to live in sandy or sandy-muddy and low turbidity still water environment, especially likes to live in clear slow-flowing water, and can adapt to slightly fertile water quality after artificial domestication. The dissolved oxygen is required to be above 1.5 mg / L, the low oxygen tolerance is stronger than that of siniperca chuatsi, the temperature range is wide, and it can survive at water temperature of 1-36.5℃, starts to feed above 10℃, and the optimal growth water temperature is 20-30℃. Micropterus salmoides also has good breeding effect in brackish water ponds. Artificial breeding of micropterus salmoides is basically carried out directly in a breeding pond, although special feed for micropterus salmoides is generally used, but a considerable part of breeders still use ice fresh fish to feed micropterus salmoides. Since micropterus salmoides has the characteristics of fearing heat and light, feeding ice fresh fish in high temperature period is beneficial to micropterus salmoides to feed in the lower layer of water body, so as to maintain high feeding state of micropterus salmoides. At this time, the quality of the breeding water body plays a crucial role in the growth of micropterus salmoides.

[0003] Therefore, the patent specification with publication number CN216135034U discloses a water body filtering and circulating device for micropterus salmoides breeding, which comprises a base, a breeding tank is arranged on one side of the top end of the base, a circulating tank is installed on the outer wall of one side of the breeding tank, a backwater pipe is installed on one side of the bottom end of the circulating tank, a switch valve is installed on one side of the surface of the backwater pipe, a circulating water pump is installed on the top end of the circulating tank, a main water pipe is connected to the input end of the circulating water pump, a secondary water pipe is installed on the end of the main water pipe away from the circulating water pump, a connecting pipe is installed on one end of the secondary water pipe, a control panel is installed on one side of the surface of the base, and the output end of the single-chip microcomputer in the control panel is electrically connected with the input end of the circulating water pump. The device not only can improve the oxygen content in the water body, but also is convenient for the staff to clean, and reduces the work intensity of the staff.

Detailed Implementation

[0028] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0029] like Figure 1 As shown, a California bass farming device includes a rearing tank 1, a net assembly 2 disposed within the rearing tank 1, a winding assembly 3 disposed on the rearing tank 1 for adjusting the height of the net assembly 2, and a feeding mechanism 4 slidably arranged on the side of the rearing tank 1 for feeding the rearing tank 1. Long, narrow slide rails 10 are respectively provided on both sides of the rearing tank 1, and the slider 40 of the feeding mechanism 4 slides in cooperation with the slide rails 10. Multiple rearing tanks 1 are installed side-by-side between the two slide rails 10, arranged along the length of the slide rails 10. Each rearing tank 1 is an open cuboid groove, and an open cuboid net is provided inside the rearing tank 1.

[0030] The inner side of the breeding box 1 is equipped with multiple inner support plates 11 that provide support for the fixed frame plate 20 and multiple guide slides 12 that provide lifting and lowering displacement guidance for the movable frame plate 21, thereby improving the smoothness of the lifting and lowering process of the movable frame plate 21.

[0031] The net assembly 2 includes a fixed frame plate 20, a movable frame plate 21, and a net body 22 disposed between the fixed frame plate 20 and the movable frame plate 21. The movable end of the lifting rope 30 of the winding assembly 3 is connected to the movable frame plate 21. The winding assembly 3 is disposed on two opposite sides of the breeding box 1. The winding assembly 3 uses a motor, a drum, and a lifting rope 30. The motor drives the drum to rotate, which in turn drives the lifting rope 30 to wind on the drum, thereby driving the movable frame plate 21 at the end of the lifting rope 30 to lift and lower. Automatic feeding is achieved by cooperating with the slide rail 10 and the feeding mechanism 4, reducing labor intensity and improving breeding efficiency. The winding assembly 3 moves the fish fry on the bottom side and inside of the net upward, so that when cleaning the bottom surface of the breeding box 1 with impurities using the lower air nozzle 18 of the serpentine air distribution pipe, damage to the fish fry caused by turbid water is avoided or greatly reduced.

[0032] like Figures 2 to 5As shown, the feeding mechanism 4 includes a slider 40, a support 41 mounted on the slider 40, and a feed hopper 42 mounted on the upper end of the support 41. A feed pipe 44 is mounted on the upper side of the slider 40 via a support block 43. A guide pipe 45, perpendicularly connected to the feed pipe 44, is mounted at the bottom of the feed hopper 42. A screw conveyor 46 is installed in the feed pipe 44, and the discharge end of the feed pipe 44 is located above the net body 22. There are two feeding mechanisms 4, located on both sides of the breeding tank 1, and used for feed and crushed chilled fish respectively. The feeding mechanism 4 uses the slider 40 to move itself sequentially to the vicinity of each breeding tank 1. During the feeding operation, the material in the hopper is transported to the feed pipe 44 through the guide pipe 45, and then fed into the breeding tank 1 through the screw conveyor 46. The feed and crushed chilled fish are fed alternately according to the feeding cycle.

[0033] A water inlet pipe 13 and an overflow pipe 14 are installed at the high position of the side panel of the rearing tank 1, and a drain pipe 15 and an air blower pipe 16 are installed at the low position of the side panel of the rearing tank 1. A serpentine distribution pipe 17 connected to the air blower pipe 16 is installed in the inner cavity of the rearing tank 1 near the ground, and multiple air nozzles 18 are installed on the serpentine distribution pipe 17. The water inlet end of the water inlet pipe 13 is located in the area between the rearing tank 1 and the net body 22, and the water inlet direction of the water inlet pipe 13 is vertically downward. An upper air passage pipe and a lower air passage pipe are respectively set in the serpentine distribution pipe 17, and air nozzles 18 are installed in the upper air passage pipe and the lower air passage pipe respectively. The upper air nozzles 18 of the serpentine air distribution pipe are used to provide uniform oxygen supply to avoid local low oxygen affecting the rearing of California bass. When cleaning the bottom of the rearing tank 1 with impurities, the lower air nozzles 18 of the serpentine air distribution pipe are used to avoid or greatly reduce the damage to the fry caused by turbid water.

[0034] A three-way valve 19 is installed at the connection point between the serpentine distribution pipe 17 and the air blower pipe 16. The three-way valve 19 switches the connection status of the upper and lower air passages of the air blower pipe 16 and the serpentine distribution pipe 17. When the three-way valve 19 switches the air blower pipe 16 to the upper air passage, the external air blower device of the air blower pipe 16 aerates the breeding tank 1. When the three-way valve 19 switches the air blower pipe 16 to the lower air passage, the external air blower device of the air blower pipe 16 aerates the breeding tank 1. The airflow cleans the impurities deposited at the bottom of the breeding tank 1, mixing them into the water. Then, the water inlet pipe 13 and the drain pipe 15 are opened for rapid water exchange. During the water exchange process, impurities are transferred to the removal point. The operation is convenient and reliable.

[0035] The present invention also provides a method for raising California bass using a farming apparatus, comprising the following steps:

[0036] S1: Feeding operation: The feeding mechanism 4, which is loaded with feed or crushed frozen fish, is moved to the vicinity of each breeding box 1 in sequence. The feed is fed into the breeding box 1 through the feed pipe 44 with screw conveyor 46. The feed and crushed frozen fish are fed alternately according to the feeding cycle.

[0037] S2: Oxygen supply operation: The three-way valve 19 switches the air pipe 16 to connect with the upper air pipeline, and the air blowing equipment connected to the air pipe 16 inflates and supplies oxygen to the breeding box 1.

[0038] S3: Water change operation: First, use the winding component 3 to lift the bottom of the net bag upwards. At this time, the fish fry will also move upwards, avoiding or greatly reducing the damage caused by turbid water. Then, switch the air pipe 16 to the lower air pipeline through the three-way valve 19. The air blowing device connected to the air pipe 16 inflates the breeding tank 1. Use the airflow to clean the impurities deposited at the bottom of the breeding tank 1 and mix them into the water. Then, open the water inlet pipe 13 and the drain pipe 15 to quickly change the water. During the water change process, the impurities are transferred and removed.

[0039] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
