Embodiment 1

[0027] Embodiment 1, a kind of fish pond

[0028] Such as Figure 1~6Shown: a fish pond, including a fish pond 1; the inner wall of the fish pond 1 has a seal cover seat 25, and the seal cover seat 25 is provided with a seal cover 4; the distance from the seal cover seat 25 to the top of the fish pond 1 is the same as the height of the seal cover 4 Equal; the sealing cover 4 is an arched structure, and an emptying valve 8 is arranged on the top of the sealing cover 4; an oxygen increasing pipe 27 is arranged in the fish pond 1 . Described aquarium is also provided with high-pressure oxygen pipe 13 and low-pressure oxygen pipe 15, and high-pressure oxygen pipe 13 is provided with intake valve 31, and low-pressure oxygen pipe 15 communicates with oxygen-increasing pipe 27; High-pressure oxygen pipe 13 and low-pressure oxygen An oxygen regulator valve 14 is arranged between the tubes 15 , and the opening and closing device 43 inside the oxygen regulator valve 14 is controlled by...

Embodiment 2

[0038] Embodiment 2, a kind of high-density culture carp method

[0039] Carp is a main cultured fish, and the breeding density in factory farming can reach 100-130kg / m 3 , a high-density culture carp method is:

[0040] (1) Throw in fry: close bottom valve 19, cleaning valve 22, bottom overflow valve 17, upper overflow valve 24, fill water in fishpond 1, put into fry.

[0041] Calculate the number of fry:

[0042]

[0043] (2) Fish pond sealing: close the feeding valve 33, the feeding valve 35, the throttle valve 36, open the emptying valve 8, place the sealing cover 4 on the sealing cover seat 25, and the air in the sealing cover 4 is discharged from the emptying valve. 8 discharge, after the water body is full of the space in the sealing cover, close the emptying valve 8; the high-pressure oxygen pipe 13 is connected to the intake valve 31, and the low-pressure oxygen pipe 15 is connected to the oxygen regulator valve 14, and the regulator value of the oxygen regulator...

Embodiment 3

[0063] Embodiment 3, a kind of method for high-density cultivation light-lipped fish

[0064] Light lip fish is a small stream fish with high requirements on dissolved oxygen and water quality. There are two methods of running water culture and cage culture, and the culture density is 5-7.17kg / m 3 . A kind of high-density breeding light lip fish method is:

[0065] (1) Throw in fry: same as embodiment 2.

[0066] Calculate the number of fry:

[0067]

[0068] (2) Sealing of fish pond: Same as Example 2.

[0069] (3) Water flow adjustment: the water inlet pipe 12 is connected to the water inlet valve 30; the water inlet valve 30 is opened, and the jet water 6 is sprayed obliquely towards the water surface 7 of the fish pond, forming a counterclockwise circulation and vortex; the jet water 6 is violently impacted and mixed with pure oxygen, and the oxygen Dissolve rapidly into the water, and the dissolved oxygen in the surface water of the fish pond reaches 37-49mg / L; the...

Abstract

The invention relates to a fishpond. The fishpond comprises a fishpond body, a sealing cover seat is arranged on the inner wall of the fishpond body and is provided with a sealing cover, the sealing cover is of arch structure, and an evacuation valve is arranged at the top of the sealing cover; an oxygenation pipe is arranged in the fishpond body. Oxygen is fed by the oxygenation pipe and undissolved oxygen rises to the upper portion of the arch sealing cover. The sealing cover and the sealing cover seat are submerged in the water to form liquid seal, and closed pure oxygen space between the sealing cover and the water surface is formed. The problems that farming density in industrial fish farming is hard to improve, oxygenation equipment is complicated, energy consumption is high, pure oxygen utilization rate is low and farming operation is inconvenient are solved, and economic benefits of the aquaculture industry are increased.

Description

technical field [0001] The invention relates to a fish pond, in particular to a fish pond and a high-density fish cultivation method, and belongs to the technical field of fish cultivation. Background technique [0002] The dissolved oxygen content of the water body is the main limiting factor of the density of fish farming. In high-density fish farming, the continuous flow and exchange of the fish farming water body provides dissolved oxygen for the fish and takes away metabolic waste. The water exchange rate in the fish pond is limited by the fish's adaptation to the flow rate, and the fish culture density in ordinary flowing water is only 10-20kg / m 3 , Artificial oxygenation can increase the dissolved oxygen content in the water body and increase the density of fish farming. Mechanical aeration is commonly used in industrial fish farming. Under the condition of using air as the oxygen source, the density of fish farming can reach 30-50kg / m 3 ;Using pure oxygen as the ox...
