Embodiment Construction

[0025] combine Figure 1-3 Shown a kind of fry hatching, cultivating pond with fish nest, comprise pond 4. The pool 4 has a water outlet and is equipped with an aeration structure, and the air outlets of the aeration structure are uniformly arranged along the periphery of the water outlet. The aeration structure produces a large number of air bubbles and fills around the water outlet. This can well prevent the water spray with weak swimming ability from entering the periphery of the water outlet, being absorbed and unable to escape, resulting in death, and effectively improving the survival rate of fry. In addition, in the hatching stage, the aeration structure can aerate and increase oxygen, provide necessary oxygen for fry hatching, and ensure a high hatching rate.

[0026] The aeration structure may be an aeration disk, and the aeration disk has many micropores, and the generated air bubbles diffuse evenly, have good anti-blocking and backflow prevention, and high oxygena...

Abstract

The invention relates to the field of aquaculture and aims at providing a fry incubation and rearing pond with fish spawning nests and improving the survival rate of fries. According to the technical scheme, the fry incubation and rearing pond with the fish spawning nests comprises a pond body, wherein the pond body is provided with a water outlet portion and a matched aeration structure, and air outlet holes of the aeration structure are evenly formed along the periphery of the water outlet portion. The aeration structure produces a large amount of air bubbles distributed around the water outlet portion. Therefore, the phenomenon that fries poor in swimming ability go to the surrounding of the water outlet portion, are sucked, cannot break away and accordingly are dead can be well prevented, and the survival rate of the fries is effectively improved. In addition, at an incubation stage, the aeration structure can play an aeration oxygenation role, necessary oxygen is provided for fry incubation, and higher incubation rate is ensured. Furthermore, the fry incubation and rearing pond is additionally provided with the fish spawning nests facilitating fish spawning, a water inlet pipeline and a water outlet system, wherein the water inlet pipeline and the water outlet system are convenient to use. The fry incubation and rearing pond is suitable for fish spawn incubation and rearing and is used in the field of aquaculture.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a fry hatching and cultivating pool. Background technique [0002] At present, in fish farming, the hatching and cultivation of fry are separated. The common practice is to place the fertilized eggs in the hatching tank first, and hatch them with flowing water. The fish fry hatched from the fertilized eggs are then transferred to outdoor ponds to be cultivated into standard seedlings, or directly cultured into commercial fish. On the one hand, this method needs to use a lot of water and occupy land, wasting resources; on the other hand, because the fry are cultivated in outdoor ponds, the breeding process is easily affected by external factors such as weather and water pollution, and the mortality rate is relatively high. [0003] Therefore, the indoor circulating water seedling system has become the future development trend of the seedling industry. However, the newly hatched fry, ...
