Embodiment Construction

[0023] Such as figure 1 As shown, a simple hatching device for fertilized eggs of puffer obscura comprises a hatching bucket 1 placed in a pool, an air duct 2, an air pump 3 and a siphon device 4, and the hatching bucket 1 includes an upper part 11 of a cylinder and a cone. The bottom 12, the upper part 11 and the bottom 12 are integrated, and the hatch tank 1 is provided with an air stone 5 and a water quality detection device 6. The air stone 5 is connected to the air pump 3 through the ventilation pipe 2, and the water quality detection device 6 can at least detect the pH value of the water body. The hatching bucket 1 is flexibly connected with the siphon device 4, and usually, the hatching bucket 1 and the siphon device 4 are only connected when changing water or sucking out fry.

[0024] Specifically, the incubator 1 is made of transparent plastic, the height and diameter of the upper part of the incubator 1 are 30cm and 40cm respectively, and the diameter and height of t...

Abstract

The invention provides a simple fertilized egg hatching device for takifugu obscurus, and particularly relates to the technical field of aquaculture. The device comprises a hatching barrel in a pond, a ventilation pipeline, an air pump and a siphon device, wherein the hatching barrel comprises a cylindrical upper part and a conical bottom part, the upper part and the bottom part are integrally formed, an air stone is arranged in the hatching barrel, and the air stone is connected with the air pump through the ventilation pipeline; the hatching barrel is movably connected with the siphon device. According to the device, the hatching barrel is placed in the pond, the temperature in the hatching barrel is convenient to control, and egg escape and fry escape are prevented; by means of the air stone, the fertilized eggs can be overturned to prevent the fertilized eggs from being attached to the wall for a long time and prevent mold growth; meanwhile, the unfertilized dead eggs are sucked out in time, so that the situation that water mold generated and affects the hatching rate is prevented.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a simple hatching device for fertilized eggs of puffer pufferfish obscura. Background technique [0002] The breeding season of wild puffer obscurus is in April, while puffer obscura obscurus, which is domesticated, has a high accumulated temperature and early maturity due to heating and breeding during the wintering period. It can usually breed at the end of February and early March. The breeding water temperature is 18°C-26°C. ℃, especially 22℃-24℃ is the best, but the outdoor water temperature in the Yangtze River Basin from February to March is only about 15℃, which is difficult to meet the hatching water temperature requirements of the fertilized eggs of puffer pufferfish. , requires large boilers, temperature-adjusting pools and other equipment, and the cost will increase significantly. At the same time, due to the small particle size of puffer pufferfish eg...
