Description
Technical field
The utility model relates to aquaculture field, is specifically related to a kind of novel fry hatching, cultivates pond.
Background technology
At present in fishery cultivating, the hatching of fry is what to be separated with cultivation link.Common practice first fertilized egg is placed in hatchery, and flowing water is hatched.Again the fry hatched from fertilized egg is transferred in outdoor ponds, is trained specification seedling, or directly cultivates into marketable fish.This way needs to use large water gaging and land occupation on the one hand, waste resource; On the other hand because fry is cultivated in outdoor ponds, the impact easily by the external factor such as weather, water pollutions in breeding process, lethality is higher.
Therefore indoor circulating water seedling system becomes nursery industry future developing trend.But squab fry, be commonly called as " spray ", Burden-Swimming Ability of KM is weak, with water movement to outlet part, on the aperture being attracted to outlet part or screen cloth, can cause death, have impact on fry survival rate.
Summary of the invention
The purpose of this utility model is to provide a kind of novel fry hatching, cultivates pond, improves fry survival rate.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of novel fry hatching, cultivation pond, comprise pond, described pond has outlet part and is supportingly provided with aeration structure, and the venthole of described aeration structure is evenly arranged along outlet part periphery.
Preferably, described aeration structure is aeration tube or aeration plate.
Preferably, described basin bottom arranges intubate, and intubate evenly sets out water voids; Described outlet part is made up of this water outlet hole; The size of described water outlet hole is less than the size that fish-egg and institute cultivate fry, or described cannula outer wall arranges the screen cloth of covering water outlet hole, the mesh of screen cloth be less than fish-egg with cultivate the size of fry.
Preferably, described aeration structure is arranged in basin bottom, around intubate.
Preferably, described intubate is positioned at pond central authorities.
Preferably, described intubate is stretched out at the bottom of pond and is connected water level balance pipe, and water level balance pipe leads to water tank, and the level height in water level balance pipe exit is consistent with liquid level in pond; Described water tank bottom is provided with return duct, and return duct connects water treatment system.
Preferably, the pipeline that described intubate connects water level balance pipe is provided with two branch roads, connects fry collecting pipe and drainpipe.
Preferably, described pond is drum-shaped, and bottom is the arc of depression; Pond is upper side water inlet, and the water inlet pipe being provided with some apertures by water inlet realizes; On described water inlet pipe, aperture is evenly distributed on the side of pipe, makes current enter pond along inwall.
Preferably, described water inlet pipe vertically arranges transparent pipe, transparent pipe lower end is connected with water inlet pipe; Described transparent pipe is carved with scale.
Advantageous Effects of the present utility model is: aeration structure produces a large amount of bubble and is full of around outlet part.Can well prevent the weak spray of Burden-Swimming Ability of KM from entering outlet part periphery like this, restrained its moves about and cannot depart from, and causes death, effectively raises fry survival rate.This external incubation period, aeration structure can play aeration oxygen replenishing effect, for fry hatching provides necessary oxygen, ensures higher incubation rate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A place enlarged drawing in Fig. 1;
Fig. 3 is B place enlarged drawing in Fig. 1.
Embodiment
The novel fry hatching of one shown in composition graphs 1-3, cultivation pond, comprise pond 4.Described pond 4 has outlet part and is supportingly provided with aeration structure, and the venthole of described aeration structure is evenly arranged along outlet part periphery.Aeration structure produces a large amount of bubble and is full of around outlet part.Can well prevent the weak spray of Burden-Swimming Ability of KM from entering outlet part periphery like this, be attracted to outlet part, cause death, effectively raise fry survival rate.This external incubation period, aeration structure can play aeration oxygen replenishing effect, for fry hatching provides necessary oxygen, ensures higher incubation rate.
Described aeration structure can be aeration plate, aeration plate has a lot of micropore, and the bubble diffusion of generation is even, anti-blocking, reverse-filling good, and oxygen-transfer efficiency is high.Or as shown in Figure 1, arrange aeration tube 7, be exactly arrange a circle pipe around intubate 5 surrounding, pipe connects air inlet pipe, and pipe is evenly provided with venthole, for evenly pouring bubble to intubate 5 periphery.The uniform bubble that aeration tube 7 is discharged forms annular curtain wall shape, can effectively prevent spray from entering drainage.
Bottom described pond 4, intubate 5 is set, intubate 5 evenly sets out water voids; Described outlet part is made up of this water outlet hole.Water outlet hole can be circular hole, easy to process and be convenient to draining; Also can be slit, water outlet be comparatively steady.By preventing fish-egg and being cultivated fry with current outflow pond 4, can be the size of described water outlet hole be less than fish-egg with cultivate the size of fry.Or as shown in Figure 1, described intubate 5 outer wall arranges the screen cloth 6 covering water outlet hole, the mesh of screen cloth 6 be less than fish-egg and cultivate the size of fry, so just without the need to limiting the size in water outlet space.Described aeration structure is arranged in bottom pond 4, around intubate 5.Described intubate 5 is positioned at pond 4 central authorities.The bubble that the aeration structure being arranged in bottom produces moves from bottom to up, spray can be avoided near intubate 5, and be attracted on water outlet hole or screen cloth 6, cause death.The intubate 5 that central authorities are arranged more is conducive to pond water outlet.
Described intubate 5 is stretched out at the bottom of pond and is connected water level balance pipe 8, and water level balance pipe 8 leads to water tank 9, and the level height in water level balance pipe 8 exit is consistent with liquid level in pond 4; Be provided with return duct 10 bottom described water tank 9, return duct 10 connects water treatment system.When in pond 4, water level is higher than water level balance pipe 8 exit, water just can overflow from this delivery port, and the return duct 10 bottom water tank 9 enters water treatment system.The level height in water level balance pipe 8 exit higher than bottom pond 4 lower than intubate topmost, preferably consistent with screen cloth 6 the top, set screen cloth 6 can be made full use of.The pipeline that described intubate 5 connects water level balance pipe 8 is provided with two branch roads, connects fry collecting pipe 11 and drainpipe 12.Fry collecting pipe 11 is in order to collect fry after terminating in order to fry rearing; A large amount of water can directly be discharged pond 4 by drainpipe 12.The function of collecting fry and draining just can be realized by the valve controlling that these two pipelines are arranged.
Described pond 4 is drum-shaped, and bottom is the arc of depression; Pond 4 is upper side water inlet, and the water inlet pipe 1 being provided with some apertures 3 by water inlet realizes.As shown in Figure 3, on described water inlet pipe 1, aperture 3 is evenly distributed on the side of pipe, makes current enter pond 4 along inwall.Make the water (flow) direction into water flow along pool side like this, around round pool directional-rotation, thus to a certain degree form the state of running water.The current of directional-rotation, coordinate radian at the bottom of pond can effectively gather dirt.Described water inlet pipe 1 vertically arranges transparent pipe 2, and transparent pipe 2 lower end is connected with water inlet pipe 1.As shown in Figure 2, described transparent pipe 2 is carved with scale.In transparent pipe 2, liquid level can increase with water feeding pressure and raise, and reduces and reduces, by the height of water level on the graduated transparent pipe 2 of observation band, can understand water feeding pressure fast, thus regulate amount of inlet water.
