Problems solved by technology

[0007] However, too high magnetization can also lead to changes in the active genes of fish, causing changes in metabolic mechanisms; too much effect on charged ions in fish embryos will affect the activity of enzymes in the development of fish embryos, and change the communication of cell membranes. Permeability, retardation, arrest or deformity of fish embryos

Embodiment 1

[0053] This embodiment is used to illustrate a kind of fish breeding device provided with a magnetizer, said fish breeding device such as figure 1 As shown, it includes: a box body 1, a controllable partition 2, an extraction pump 3, a magnetizer 4, a water inlet system 7, a water outlet system 8, and an online water quality monitoring device 9.

[0054] The controllable baffle 2 is arranged inside the box body 1 for partitioning the inner space of the box body 1 to form an eating area 5 and a non-eating area 6 .

[0055] The precipitation area 10 is the area where the bait settles after feeding, and its height is generally 1 / 5-1 / 4 of the feeding area 5 . The magnetizer 4 is an electromagnetic magnetizer, which is arranged on the outer wall of the box of the sedimentation area 10 (at the bottom 1 / 5-1 / 4 of the feeding area), and is used to control the water body in the feeding area 5, especially the sedimentation area. 10 water bodies are magnetized using a pulsed magnetic fie...

Embodiment 2

[0058] Utilize the fish breeding device that is provided with magnetizer described in embodiment 1, simulate and utilize method of the present invention to carry out grass carp culture in laboratory.

[0059] Experimental Materials:

[0060] Two long 200cm, wide 100cm, high 100cm cabinets (respectively the experimental group and the control group), the left side and the right side of the cabinet are respectively provided with a water inlet pipe and an outlet pipe with a diameter of 100mm.

[0061] An electromagnetic magnetizer with a magnetic field strength of 500-1000 mT was set outside the precipitation area of ​​the experimental group, and no magnetic field was set in the control group, and other conditions were the same.

[0062] 20 grass carp (approximately 250g / carp) are cultured in the tank respectively. The pH value of the water used for fish farming is 8.0, the molecular ammonia is ≤0.02mg / l, the concentration of dissolved oxygen is 4mg / L, the temperature is 18°C, and...

Embodiment 3

[0066] Take healthy grass carp eggs, artificially inseminate them by dry method, divide the fertilized eggs of the same fish into two parts, one part of the egg membrane absorbs magnetized water (the magnetic field strength is 700-1000mT, the flow rate is 20 ml / min) to expand, and the other part One piece of egg membrane absorbs ordinary fish water (slightly alkaline (pH8.0), hardness 6, transparency about 30 cm, dissolved oxygen 4 mg / L) to expand, and put the two kinds of fertilized eggs into magnetized water or ordinary water respectively. In the container of fish culture water, incubate in the petri dish of 9 centimeters in diameter in the laboratory, one group is the fertilized eggs of common water treatment, another group is the fertilized eggs of magnetized water treatment.

[0067] Each large group is further divided into 2 subgroups, and 60 fertilized eggs are placed in each group, 30 eggs are placed in each petri dish, and 40 milliliters of magnetized water or tap wate...

Abstract

The invention relates to the technical field of aquaculture, and specifically discloses a fish breeding device equipped with a magnetizer and a method for accelerating the normal reproduction and growth speed of fish. The fish breeding device includes: a box body, a controllable partition, an extraction pump and a magnetizer; the controllable baffle is arranged inside the box body to partition the inner space of the box body to form a feeding area and a non-feeding area. Eating area; the top of the controllable baffle is provided with an extraction pump for exchanging the water in the eating area and the non-eating area; the magnetizer is arranged on the outer wall of the box corresponding to the eating area for Magnetize the water body in the feeding area. The invention further incubates the fish eggs with magnetized water, and uses an adjustable magnetic field to act on the developing fish, so that the fish can reproduce and grow normally without problems such as embryo development retardation, stagnation, deformity, etc., and can realize the feeding process at the same time The purification of pollutants produced in the process improves the utilization rate of the feed in the breeding process, and the use of intermittent magnetization saves power consumption.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a fish breeding device equipped with a magnetizer and a method for accelerating the normal reproduction and growth speed of fish. Background technique [0002] The magnetization treatment of water is to use the magnetic field effect on the treatment of water to carry out the scale inhibition treatment process of water. When the water passes through the gap between the NS poles of the two permanent magnets, the magnetic force lines of the magnetic field are cut off, and the water can be magnetized. [0003] In the prior art, there have been technical solutions for magnetizing seawater to improve water quality, increase the content of dissolved oxygen in the water, and promote the development and hatching of fish eggs. Jiang Jingtian and others conducted experiments on the effects of magnetized water on the embryonic development of grass carp, silver carp, and bighead carp in ...
