Problems solved by technology

Sea bass is a nutritious fish, but the average sea bass grows for a long time, and the survival rate of juveniles is low
The traditional pond culture of perch is to put seedlings directly in the pond of 5-10 mu. Since the juvenile fish cannot get enough basic bait, the survival rate of the fry is low.

Embodiment 1

[0031] Follow the steps below for sea bass farming:

[0032] (1) Preparation of the breeding pond: The area of ​​the pond is 8 mu. After the breeding pond has been cleared, dig a trench and bury the net in the pond. The height of the net is equal to the surface of the pond, such as figure 1 As shown, the pond comprises a primary cultivation pond, a secondary cultivation pond and a tertiary cultivation pond. In the pond, a third-level cultivation pond is surrounded by a net 1 and a pond base, and a part of the net 1 and a net 2 are used in the three-stage cultivation pond. Surround the secondary cultivation pool with the pond base, encircle the first-level cultivation pool with a part of net 3, net 2 and the pond base in the secondary cultivation pool, and the area of ​​the first-level cultivation pool is 200m 2 , the area of ​​the secondary cultivation pool is 500m 2 , the area of ​​the tertiary cultivation pool is 800m 2 , a 40-watt lighting lamp is set above the first-lev...

Embodiment 2

[0041] Follow the steps below for sea bass farming:

[0042] (1) Preparation of the breeding pond: The area of ​​the pond is 6 mu. After the breeding pond has been cleared, dig a ditch and bury the net in the pond. The height of the net is equal to the surface of the pond. In the pond, use nets and pond bases to enclose a three-level cultivation pool, use nets and pond bases to enclose a second-level cultivation pool in the third-level cultivation pool, and use nets and pond bases to enclose in the second-level cultivation pools A first-level cultivation pool is produced, and the area of ​​the first-level cultivation pool is 160m 2 , set a 40-watt lighting lamp on the first-level nursery pool, the area ratio of the first-level nursery tank, the second-level nursery pool, and the third-level nursery pool is 2:5:8, and the aperture size of the net is such that fry are not allowed to pass through That’s it; at the other corner of the pond relative to the first-level cultivation ...

Embodiment 3

[0051] Follow the steps below for sea bass farming:

[0052] (1) Preparation of the breeding pond: The area of ​​the pond is 10 mu. After the breeding pond has been cleared, dig a ditch and bury the net in the pond. The height of the net is equal to the surface of the pond. In the pond, use nets and pond bases to enclose a three-level cultivation pool, use nets and pond bases to enclose a second-level cultivation pool in the third-level cultivation pool, and use nets and pond bases to enclose in the second-level cultivation pools The first-level cultivation pool was released, and the area of ​​the first-level cultivation pool is 210m 2 ,, set a 40-watt lighting lamp on the first-level nursery pond, the area ratio of the first-level cultivation pond, the second-level cultivation pond, and the third-level cultivation pond is 2:5:8, and the aperture size of the net is such that the fish fry cannot pass through Just pass through; use a net and a pond base to enclose a filter-feed...

Abstract

The invention, which belongs to the technical field of the aquatic livestock culturing, particularly relates to a four-level culture method of a lateolabrax japonicus pond. First-level cultivation, second-level cultivation, third-level cultivation, and adult fish cultivation are carried out on lateolabrax japonicus in a pond successively. A third-level cultivation pond is encircled by a net and a pond base in a pond; a second-level cultivation pond is encircled by a net and a pond base in the third-level cultivation pond; and a first-level cultivation pond is encircled by a net and a pond base in the second-level cultivation pond. According to the invention, with optimization of the culturing technology in a graded culturing mode, ways containing the culturing means like ecological mixed breeding are improved; the seedlings can be domesticated to eat food in a centralized mode and thus seedlings with uniform sizes can be cultivated; the yield of the fries can be improved; the average acre yield of the lateolabrax japonicus can be increased; and the comprehensive benefits of the lateolabrax japonicus culturing can be improved.

Description

technical field [0001] The invention belongs to the technical field of aquatic animal breeding, in particular to a four-stage breeding method for perch in ponds. Background technique [0002] Striped bass( Lateolabrax japonicus ), also known as perch, sea bass, wide temperature, wide salt fish. Sea bass contains nutrients such as protein, fat, and carbohydrates, as well as vitamin B2, niacin, and trace amounts of vitamin B1, phosphorus, and iron. Perch can nourish the liver and kidney, strengthen the spleen and stomach, reduce phlegm and relieve cough. It has a good tonic effect on people with insufficient liver and kidney. Sea bass is a nutritious fish, but the general sea bass grows for a long time, and the survival rate of juvenile fish is low. The traditional pond culture of perch is to put seedlings directly in the ponds of 5-10 mu. Since the juveniles cannot get enough basic bait, the survival rate of the fry is low. Contents of the invention [0003] The purpose...
