Description

A kind of air lift type circulating water device of suitable monomer spat of oyster cultivation
Technical field
It the utility model is related to a kind of cultchless oyster seedling breeding apparatus, and in particular to a kind of suitable monomer spat of oyster, which is cultivated, to be used Air lift type circulating water device.
Background technology
Cultchless oyster is free, without adhesive substrate oyster.Oyster has the life habit of clustering, normal multiple oyster sets Together, due to the limitation of growing space, hull shape irregular, it is attractive in appearance greatly to have impact on shell.Clustering also results in oyster and existed Competition on food, influence its speed of growth.Cultchless oyster is because its free property by growing space without being limited, thus hull shape Rule is attractive in appearance, uniform in size, is easy to put in a suitable place to breed and harvests, while improves the value and quality of oyster, and price is also costly.Mesh The mainly cultchless oyster of preceding external oyster culture, China just started to walk in recent years.
The formation of cultchless oyster is when oyster larva eyespot occurs and has settlement and metamorphosis ability, it is carried out a series of Physics and chemical treatment, single free oyster, but the cultchless oyster seedling after processing are made, because of changing for ecological habit Become, the cultivation death rate is very high, although favorably being cultivated at present with upwelling and downwelling method, due to troublesome in poeration, it is necessary to water Pump does not stop to draw water, and the death rate is also higher, and survival rate highest is usually no more than 20%, and there is presently no suitable large-scale production list The device that the body spat of oyster is cultivated.
Therefore, there is an urgent need to it is a kind of it is simple to operate, save labor, ambient stable, the convenient cultchless oyster seedling scale of management Metaplasia produces breeding apparatus, to improve the cultivating survival rate of cultchless oyster seedling.
The content of the invention
The purpose of this utility model is to provide a kind of air lift type circulating water device of suitable monomer spat of oyster cultivation, its energy Overcome disadvantages mentioned above present on existing cultchless oyster seedling cultivation.
A kind of air lift type circulating water device of suitable monomer spat of oyster cultivation, the device include open case body, should The bottom of case body is surrounded by snap ring, and the snap ring is used to fix polyethylene screen cloth, and the top of the case body is fixed with multiple Polyethylene rope, ball float is fixed with again on the polyethylene rope;The case body, should by siphon pipe of the upper opening insertion with elbow Gas stone is provided with siphon pipe, and the gas stone carries inflated hose again.
Further, for the case body by the vinyon hard tube with a diameter of 35-40cm, it is 40- to be cut into height The cylinder unit of 50cm open at both ends.
Further, the specification of the polyethylene screen cloth can be depending on the size according to cultchless oyster seedling, and regularly replaces.
Further, the number of the ball float is preferably 4.
Further, the siphon pipe is that PVs of the diameter 35-40mm with elbow is managed.
Further, the inflated hose is connected with the aerating device outside the device.
The advantages of the utility model and technique effect:
Directly cultchless oyster can be placed on using the present apparatus on screen cloth, adds the water of bait from the top of device, utilize rainbow Suction pipe enters water suction in device under conditions of inflation, is discharged by the screen cloth of bottom of device, forms oxygen and fill Sufficient air water semi-aerobic landfill, it ensure that cultchless oyster seedling fast-growth is developed, survival rate greatly improves, and can be up to more than 50%.
The present apparatus is simple in construction, be skillfully constructed, cost is extremely low, and is easy to manage, and can carry out popularization and application, be especially suitable for The extensive cultivation of cultchless oyster seedling.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Wherein, 1- casees body, 2- snap rings, 3- polyethylene screen clothes, 4- polyethylene ropes, 5- ball floats, 6- siphon pipes, 7- gas stones, 8- inflated hoses.
Embodiment
It is explained further and illustrates below by way of embodiment and with reference to accompanying drawing to the utility model.
As shown in figure 1, a kind of air lift type circulating water device of suitable monomer spat of oyster cultivation, it is characterized in that by with diameter For(35-40)Cm vinyon hard tube, making height is(40-50)The open case body 1 in cm two, the bottom of case body 1 Portion is with snap ring 2 by diameter(50-55)Cm polyethylene screen cloth 3 entangles fixation, and it is enterprising that cultchless oyster seedling is placed on into polyethylene screen cloth 3 Row is cultivated, and polyethylene screen cloth specification can be depending on the size according to cultchless oyster seedling, and regularly replaces, and device upper orifice surrounding is used There are 4 ball floats 5 in the system of polyethylene rope 4, and there are the PV siphon pipes 6 that diameter 35-40mm carries elbow the top side of device 1, is inside inserted with The gas stone 7 and inflated hose 8 of inflation, the water in siphon pipe is siphoned into device 1 using inflation, forms an air water recirculated water System.
In use, the device is put into the nursery pond of topped up with water, in the presence of ball float 5, device, which is unlikely to sink to, educates Miao Chi bottom, directly cultchless oyster seedling is placed on polyethylene screen cloth 3, adds the water of bait from the top of device, Yi Jichong Gas flexible pipe 8 by outside aerating device deliver the gas to gas stone 7, finally using siphon pipe 6 under conditions of inflation water Suction is entered in device, is discharged by the polyethylene screen cloth 3 of bottom of device, is formd oxygen sufficient gas water circulation water planting and educate.
It multigroup can be arranged and used in culture pond according to the quantity of cultchless oyster seedling, each device can put 0.35-0.40mm Cultchless oyster seedling 60-100 ten thousand, 10-20 ten thousand can be put after 0.5mm.Through actual verification, using the utility model, ensure The development of cultchless oyster seedling fast-growth, survival rate greatly improve, and can be up to more than 50%.
It is described above, only it is preferred embodiment of the present utility model, is not to this new limit for making other forms System, any person skilled in the art are changed or are modified as equivalent variations possibly also with the technology contents of the disclosure above Equivalent embodiment.But every content without departing from this new technique scheme, the technical spirit new according to this are real to more than Any simple modification, equivalent variations and remodeling that example is made are applied, still falls within the protection domain of this new technique scheme.
