Abstract

The invention provides a floating net cage used for cultivating individual seed oysters in an outdoor soil pond. The floating net cage used for cultivating the individual seed oysters in the outdoor soil pond comprises a frame formed by welding steel bars, a screen surrounds the bottom and the periphery of the frame, a floating ball is arranged on the top of the frame, and a weight for weighing down is arranged on the bottom of the frame. According to the floating net cage used for cultivating the individual seed oysters in the outdoor soil pond, the individual seed oysters can be directly arranged on the net cage, the individual seed oysters can be cultivated in a large scale by taking full advantages of water body of the outdoor soil pond, the individual seed oysters are high in growth speed, high in survival rate and convenient to manage, operation is easy to carry out, and time and labor are saved.

Description

A kind of floating net cage of using for outdoor earth pond cultivation cultchless oyster seedling
Technical field
The present invention relates to fish production technical field of tools, particularly a kind of floating net cage of using for outdoor earth pond cultivation cultchless oyster seedling.
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, and it is carried out to a series of physics and chemistry processing, and making it becomes single free oyster, but the cultivation of cultchless oyster seedling is after treatment cumbersome.
Summary of the invention
The invention provides and a kind ofly for outdoor earth pond, cultivate the floating net cage that cultchless oyster seedling is used, with provide a kind of simple to operate, save labor, the cultchless oyster seedling large-scale production breeding arrangement of ambient stable, convenient management.
To achieve these goals, the invention provides following technical scheme:
For outdoor earth pond, cultivate the floating net cage that cultchless oyster seedling is used, it comprises: the framework being welded by reinforcing bar, and screen cloth surrounds bottom and the surrounding of described framework, and the top of described framework is provided with ball float, and described base of frame is provided with the weight of heavy pendant.
Preferably, the top of described framework is connected with ball float by polyethylene rope.
Preferably, on four of the bottom of described framework angles, be provided with dropstone.
Preferably, the diameter of described reinforcing bar is 8-10mm, and the length of described framework is respectively: (200-300) cm, (100-150) cm, (20-30) cm.
By implementing above technical scheme, there is following technique effect: the floating net cage of using for outdoor earth pond cultivation cultchless oyster seedling provided by the invention, can directly cultchless oyster seedling be placed on net cage, 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, simple to operate, save labor.
Accompanying drawing explanation
Fig. 1 is the structural representation of the floating net cage of using for outdoor earth pond cultivation cultchless oyster seedling provided by the invention.
Embodiment
Technical scheme for a better understanding of the present invention, describes embodiment provided by the invention in detail below in conjunction with accompanying drawing.
The embodiment of the present invention provides a kind of and cultivates for outdoor earth pond the floating net cage that cultchless oyster seedling is used, as shown in Figure 1, comprise: the framework 1 being welded by reinforcing bar, this reinforcing bar scribbles antirust paint and gets rusty preventing, screen cloth 2 surrounds bottom and the surrounding of described framework 1, the top of described framework 1 is provided with ball float 4, and described framework 1 bottom is provided with the weight 5 of heavy pendant.In the above-described embodiments, preferably, the top of described framework 1 is connected with ball float 4 by polyethylene rope 3, and preferably, this polyethylene rope 3 is that the thin polyethylene rope coiling of 12 strands forms, and prevents from rotting.In the above-described embodiments, this screen cloth is polyethylene screen cloth, and the mesh of this screen cloth is determined according to the size of cultchless oyster seedling.Five of framework 1 are wrapped by screen cloth, and one side is upward uncovered.
In the various embodiments described above, preferably, described weight 5 is dropstone, and this dropstone is lifted on four angles of the bottom of described framework 1, so that this floating net cage is stable, floats in water.
In the various embodiments described above, preferably, the diameter of described reinforcing bar is 8-10mm, and the length of described framework is respectively: (200-300) cm, (100-150) cm, (20-30) cm.
A kind of floating net cage of using for outdoor earth pond cultivation cultchless oyster the seedling above embodiment of the present invention being provided is described in detail, for one of ordinary skill in the art, thought according to the embodiment of the present invention, all will change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
