Description

Cycle water fish seedling fostering system
Technical field
The utility model relates to the field of industrial circulating water fish seedling fostering system, specifically a kind of complete set of equipments for the fry rearing of fish cycle water.
Background technology
The cycle water seedling fostering system that present society uses is also few, still adopts more original cement pit nursery, and adopts the nursery of running water mode.The system that cycle water can be adopted to carry out nursery is also buy or copy external complete set of equipments, but these systems and mode all exist following problem, thus it is not high to lead nursery output, and weed survival rate is lower:
One, nursery pond design aspect is appeared in problem set.Nursery pond part in existing cycle water seedling system is nearly all adopt circular, square or hexagonal pond type design (this design is understood have more about 20% floor space than rectangle), and the most the underlying cause adopting this design is in order to pond bottom blowdown.At the bottom of these nursery pond ponds, design is all based on pot bottom-shape, by different modes, the water in pond is rotated, the centrifugal force that the current rotated in pond produce can by the solid impurity such as ight soil, residual bait to pond intermediate collection, thus reach the object of contamination, then by the blowdown design be positioned in the middle of pond, dirt is discharged.The shortcoming of this kind of design is:
1, current are too little cannot reach contamination object, current too conference hurt fry, and small and weak fry also can be focused on centre by too large current, causes fry skewness in pond, the shoal of fish of concentrating also can cause the dissolved oxygen in the water of pond also uneven, affects the normal growth of fry.This design is unreasonable, wastes the space in nursery pond.And concentrate on middle dirt and small and weak fry mixed in together, the cheek of hatching can be caused to be subject to the obstruction of dirt, and hatching also can cause bacteriological infection and dead, the nursery production directly affected because of the dirt be centered around at one's side.
2, when dirt is middle close to pond time, because solid dirt loses original linear velocity, thus fall at the bottom of pond and cannot advance, that is dirt cannot arrive sewage draining exit smoothly, and filth-discharging effect is poor, and cause pool inner water qualitative change bad, pathogen content is higher.
3, some system devises auxiliary blowdown apparatus at sewage draining exit.As copied the sewage suction device of the back-off butterfly of Norway's circulating water culture system, though filth-discharging effect makes moderate progress, small and weak fry is easy to be inhaled in blow-off pipe dead; Some design have employed the mode adding screen pack at sewage draining exit and carries out blowdown, this design causes hatching to be easy to be adsorbed to and screen pack cannot to escape and dead, and the screen pack be at the bottom of pond easily blocks, can not get clearing up the operation that just can affect whole circulation timely.

Although 3, whole set process has carried out Protein Separation to larval rearing water, but owing to lacking relevant device in nursery pond, a lot of foams can be caused to discharge in time due to current or inflation in pond, these foams (mainly grease, albumen and tiny organic debris) can become vegetative hotbed, also can polluted water, directly have influence on survival rate and the healthy growth of immature fry in pond.
4, on enriching step, substantially adopt inflation and add pure oxygen to realize, but owing to lacking de-airing step in technological process, the carbonic acid gas that fry can be caused to breathe out cannot be discharged in time from water, the carbonic acid gas of high concentration can make oxygen be added in water, thus causes dissolved oxygen in water not enough.With airing form oxygenation, the current dissolved oxygen of inflation damages small and weak fry, and the nature of fry adverse current can make to occur in pond that injection section fry is too concentrated, fry skewness in pond.Being dissolved in water by pure oxygen by pressurization to cause part pure oxygen to be again reduced into gaseous state in water He in fry body, makes fry suffer from bubble illness and dead.
Three, the operating aspect in seedling raising process.No matter be the nursery of conventional cement pond or employing cycle water nursery pond, the pond or receipts seedling (when pulling fry out nursery pond) operation of seedling raising process all still adopt the mode of manually dragging for seedling, is not directed to this operation specially and does any design.Because this to operate in seedling raising process very frequent, not only waste a lot of artificial, also have a lot of fry dead because operating the mechanical damage that is subject to for this reason.
