Description
Technical field
The utility model relates to fish production technical field of tools, particularly a kind of floating net cage cultivating cultchless oyster seedling for outdoor earth pond.
Background technology
Cultchless oyster namely free, without the oyster of adhesive substrate.Oyster has the life habit of clustering, and normal multiple oyster anchors at together, and due to the restriction of growing space, hull shape irregular, have impact on attractive in appearance widely.Clustering also causes the competition of oyster on food, affects its growth rate, and cause individual difference large, commodity economy is worth low.The heavy adherance such as scallop shell, tile, allows porter do the labour of at substantial; Because oyster set is firm, artificially one by one oyster must be peeled away during results, bring inconvenience to the results of oyster, both affected operating efficiency, be also unfavorable for deep processing.The restriction of cultchless oyster due to its free property not by growing space, thus hull shape rule is attractive in appearance, and size is even, 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 namely eyespot has settlement and metamorphosis ability, carries out a series of physics and chemistry process to it, makes it to become single free oyster, but the cultivation of cultchless oyster seedling after treatment, cumbersome.
Utility model content
The utility model provides a kind of floating net cage cultivating cultchless oyster seedling for outdoor earth pond, 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 utility model provides following technical scheme:
Cultivate a floating net cage for cultchless oyster seedling for outdoor earth pond, it comprises: by the framework of reinforcement welding, 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, four angles of the bottom of described framework are 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 cultivating cultchless oyster seedling for outdoor earth pond that the utility model provides, can directly cultchless oyster seedling be placed on net cage, outdoor earth pond water body can be made full use of and cultivate cultchless oyster seedling on a large scale, cultchless oyster seedling fast growth, survival rate is high, is convenient to management, simple to operate, save labor.
Accompanying drawing explanation
The structural representation cultivating the floating net cage of cultchless oyster seedling for outdoor earth pond that Fig. 1 provides for the utility model.
Embodiment
In order to better understand the technical solution of the utility model, describe below in conjunction with accompanying drawing the embodiment that the utility model provides in detail.
The utility model embodiment provides a kind of floating net cage cultivating cultchless oyster seedling for outdoor earth pond, as shown in Figure 1, comprise: by the framework 1 of reinforcement welding, this reinforcing bar scribbles antirust paint to prevent from getting rusty, screen cloth 2 surrounds bottom and the surrounding of described framework 1, the top of described framework 1 is provided with ball float 4, is provided with the weight 5 of heavy pendant bottom described framework 1.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, and to make, this floating net cage is stable to be floated 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.
Above a kind of floating net cage for outdoor earth pond cultivation cultchless oyster seedling that the utility model embodiment provides is described in detail, for one of ordinary skill in the art, according to the thought of the utility model embodiment, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
