Description

A kind of cultchless oyster seedling is cultivated the simple and easy upwelling device of use
Technical field
The utility model relates to a kind of cultchless oyster seedling nursing device, particularly relates to the simple and easy upwelling device that a kind of cultchless oyster seedling is cultivated use.
Background technology
Cultchless oyster free, without the oyster of adhesive substrate.Oyster has the life habit of clustering, and normal a plurality of oysters anchor at together, and due to the restriction of growing space, hull shape irregular, has affected attractive in appearance widely.Clustering also causes the competition of oyster on food, affects its growth rate.Cultchless oyster is not subject to the restriction of growing space due to its free property, thereby hull shape rule is attractive in appearance, and size evenly, is easy to put in a suitable place to breed and gather in the crops.Cultchless oyster is convenient to the research work in laboratory, is easy to observe and measure.
The formation of cultchless oyster is when oyster larva occurs that eyespot has settlement and metamorphosis ability; it is carried out to a series of physics and chemistry processing; make it to become single free oyster; but the cultivation of cultchless oyster seedling after treatment; cumbersome; also be not applicable at present the apparatus and method of large-scale production, therefore, in the urgent need to a kind of simple to operate, save labor, the cultchless oyster seedling large-scale production breeding arrangement of ambient stable, convenient management.
Summary of the invention
The purpose of this utility model is to provide the device that a kind of cultchless oyster seedling is cultivated use, and it can overcome existing cultchless oyster seedling and cultivate the upper above-mentioned shortcoming existing.
A kind of cultchless oyster seedling is cultivated the simple and easy upwelling device of use, it is characterized in that by diameter be (60-65) cm, the high vinyon drum for worn-out mouthful of (40-50) cm, bottom margin is provided with water inlet valve, gap is arranged at top, there is tabula at middle part, on tabula, straighten footpath (59-64) cm polyethylene screen cloth, polyethylene screen cloth specification can be determined according to the size of cultchless oyster seedling, according to the quantity of cultchless oyster seedling, can organize in parallel use more.
The utility model can directly be placed on cultchless oyster on screen cloth, adds the water of bait to enter from the bottom of Plastic Drum, by the overflow pipe of vinyon drum, discharges, by flowing water, cultivate, cultchless oyster seedling fast growth, survival rate is high, be convenient to management, can cultivate on a large scale cultchless oyster juvenile mollusk.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
Embodiment
A kind of cultchless oyster seedling is cultivated simple and easy its feature of upwelling device of use, to be that (60-65) cm, height are the uncovered vinyon drum 1 of (40-50) cm by diameter, bottom margin is provided with water inlet valve 2, gap 3 is arranged at top, there is tabula 4 at middle part, on tabula 4, straighten footpath (59-64) cm polyethylene screen cloth 5, polyethylene screen cloth specification can be determined according to the size of cultchless oyster seedling, according to the quantity of cultchless oyster seedling, can organize in parallel use more.
The utility model can directly be placed on cultchless oyster on screen cloth, add the water of bait to enter from the bottom of Plastic Drum, overflow pipe by vinyon drum is discharged the water with ight soil, by flowing water, cultivate, cultchless oyster seedling fast growth, survival rate is high, is convenient to management, can cultivate on a large scale cultchless oyster juvenile mollusk.
