Description

A kind of outdoor earth pond is cultivated the multilayer floating net cage that cultchless oyster seedling is used
Technical field
The utility model relates to a kind of cultchless oyster seedling nursing device, particularly relates to a kind of outdoor earth pond and cultivates the multilayer floating net cage that cultchless oyster seedling is used.
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, causes individual difference large, and commodity economy is worth low.The adherances such as heavy scallop shell, tile, allow porter expend a large amount of labours; Because oyster set is firm, during results, must artificially one by one oyster be peeled away, brought inconvenience to the results of oyster, both affected operating efficiency, be also unfavorable for deep processing.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.
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, indoor raising of seedling pond cultivation floor space is large, operate cumbersome, mainly abroad to adopt upwelling device, only be applicable to the production of growing seedlings on a small scale, 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, ambient stable, the cultchless oyster seedling large-scale production breeding arrangement of 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 outdoor earth pond is cultivated the multilayer floating net cage that cultchless oyster seedling is used, it is characterized in that the steel bar welding growth 150-200cm * wide 100-120cm that the scribbles antirust paint * high 100-120cm framework by diameter 8-10mm, divide 3 layers, between layers apart from 30-35cm, then with polythene net sheet by bottom with the 150-200cm that all around grows up * wide 100-120cm * high 15-20cm net cage, top is opening, the mesh of polythene net sheet is determined according to the size of cultchless oyster seedling, multilayer floating net cage is to be on the floating well rope of outdoor earth pond setting by 18-20 thigh polyethylene rope, four jiaos of base of frame are provided with four dropstones and play fixation.Concrete framework is established the net cage number of plies and specification and is determined according to the outdoor earth pond depth of water and convenient management.
The utility model can directly be placed on cultchless oyster seedling on floating net cage, and can make full use of outdoor earth pond water body and cultivate on a large scale cultchless oyster seedling, cultchless oyster seedling fast growth, survival rate is high, is convenient to management.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
Embodiment
A kind of outdoor earth pond is cultivated the multilayer floating net cage that cultchless oyster seedling is used, it is characterized in that the steel bar welding growth 150-200cm * wide 100-120cm that the scribbles antirust paint * high 100-120cm framework 1 by diameter 8-10mm, divide 3 layers, between layers apart from 30-35cm, then with polythene net sheet by bottom with the 150-200cm that all around grows up * wide 100-120cm * high 15-20cm net cage 2 (not marking in figure), top is opening, the mesh of polythene net sheet is determined according to the size of cultchless oyster seedling, multilayer floating net cage is to be on the floating well rope of outdoor earth pond setting by 18-20 thigh polyethylene rope 3, four jiaos of base of frame are provided with 4 fixations of four dropstones.Concrete framework is established the net cage number of plies and specification and is determined according to the outdoor earth pond depth of water and convenient management.
The utility model can directly be placed on cultchless oyster seedling on floating net cage, and can make full use of outdoor earth pond water body and cultivate on a large scale cultchless oyster seedling, cultchless oyster seedling fast growth, survival rate is high, is convenient to management.
