Abstract

The utility model relates to a sinking type bait platform used for grass carp net cage seedling culture. The sinking type bait platform used for the grass carp net cage seedling culture is composed of a sling (1), a supporting frame (2), a net surface (3) and a sinker (4), wherein one end of the sling (1) winds the top end of the supporting frame (2), the net surface (3) is supported by the supporting frame (2), the sinker (4) is hung at the connection position between the net surface (3) and the supporting frame. The sinking type bait platform used for the grass carp net cage seedling culture is designed according to feeding habit of grass carp seedlings and structural features of a net cage, thereby being simple in structure, easy to manufacture and convenient to manage. In the process of culture, the sinking type bait platform used for the grass carp net cage seedling culture can be further used for collecting a few of grass carp seedlings, and growth situation and health condition of the grass carp seedlings can be conveniently observed.

Description

A kind of grass carp net cage seedling nursery is with heavy property bait table

Technical field:

The utility model relates to a kind of growing seedlings and uses device for feeding, and especially a kind of grass carp net cage seedling nursery is with heavy property bait table.

Background technology:

Grass carp is the important cultured freshwater fish of China, has long breed history in China, but owing to reasons such as the continuous deteriorations of water resource environment; Grass carp germ plasm resource is challenged; For the consumption demand of satisfying people and the sound development that realizes the grass carp aquaculture, breeding grass carp work comes into one's own gradually, and especially family selective breeding enjoys favor as a kind of effective conventional selection; Independent cultivation family fry is the important step in the whole breeding process; The family of aquatic livestock small-sized net cages or the little ponds of adopting of growing seedlings are independently cultivated more, and carry out the work of grass carp family selective breeding, and it is most important to solve the early stage bait feeding problem that little water body grows seedlings.

More the cage culture purpose has application, but does not see the research that the fry rearing of being applied to is arranged in little water body environment, carrying out high-density breeding in the grass carp fingerling is cultured.It is little with the net cage mesh to grow seedlings, and the inside and outside water body exchange rate of case is little, and aquaculture management is had requirements at the higher level.The mode of throwing something and feeding of net cage seedling nursery is different from that grow seedlings in the pond and the cage culture fingerling; The extensive style mode of throwing something and feeding is underestimated bait, often throws something and feeds excessive and produces a large amount of residual baits, not only wastes bait; And very easily cause the net cage water body to worsen and receive disease threatening, influence the process of growing seedlings.In addition, because the less not easily collecting of fry is unfavorable for grasping fry progress situation through observing the young.

The utility model content

The utility model technical problem to be solved provides a kind of simple in structure, makes easily convenient management; Be easy to throw something and feed and clear up; And be applicable to and collect fry, be convenient to observe that fry ingests, the heavy property bait table of growth and health status, to overcome the above-mentioned technical problem of existing in prior technology.

The technical scheme of the utility model is:

A kind of grass carp net cage seedling nursery is used heavy property bait table, by lanyard, and support, wire side and sinker are formed, and an end of lanyard is wound in cantilever tip, and wire side is by stent support, and sinker hangs the junction at wire side and support from above.

As the further improvement of the utility model, said support is formed by two rubber-like bamboo chips intersections, and said wire side is a square, and the two ends of each bamboo chip link to each other with a diagonal angle of said wire side.

As the further improvement of the utility model, said wire side is 100 order yarn tulle cloth.

As the further improvement of the utility model, said sinker is iron hoop or nut.

The bait table of the utility model is according to grass carp fry eating habit and the design of cage structure characteristics; Bait table is hung on net cage on one side; Hanging down and lean on wire side in the net cage in the adjacent both sides of support, helps the stability that improves bait table, reduces stormy waves and impact the influence that bait is flown away; Keep wire side under water about 30 centimetres, when throwing something and feeding bait is held on the wire side and get final product, can grasp the fry situation of ingesting, be convenient in time clear up unnecessary residual bait, prevent residual bait corruption pollution net cage microenvironment through residual bait amount on the wire side; In cultivating process, the utility model also can be used for collecting a small amount of fry, is convenient to observe fry growing state and health status.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment.

Embodiment

Below in conjunction with accompanying drawing, further set forth the utility model.

Referring to Fig. 1; Grass carp net cage seedling nursery shown in the figure is with sinking the property bait table by lanyard 1, support 2, wire side 3 and sinker 4 compositions; Support 2 is formed by two rubber-like bamboo chips intersections; Bamboo chip is difficult for corrosion in water, a diagonal angle of the two ends of each bamboo chip and square wire side 3 links together, and utilizes the favorable elasticity of bamboo chip to support wire side 3.Wire side 3 is processed by 100 order yarn tulle cloth, and its four angle seam places leave latch closure or cloth, is used for rigid support 2 and hangs sinker 4 from above, and sinker 4 is iron hoop or nut, plays firm bait table.Rope 1 adopts common nylon rope, and an end is wound in two bamboo chip infalls of support, and the other end can be used to tie up on the net cage.

During use, the vacant end system of lanyard 1 is hung over the central authorities on a limit of net cage, hanging down and lean against the interior wire side of net cage in the adjacent both sides of support 2, makes bait table more stable like this, reduced stormy waves simultaneously and impacted the influence to bait table; Wire side 3 is remained on about 30 centimetres of underwaters; Can observe the fry feeding behaviour, when throwing something and feeding bait is held on the wire side 3, regulate feeding volume through the residual bait amount on the wire side 3; And in time clear up unnecessary residual bait; Slowly mention bait table during cleaning, avoid residual bait to fly away, cause the corrupt net cage water environment of polluting of residual bait; Can collect a small amount of fry through mentioning bait table when throwing something and feeding, inspection fry growing state and health status.

More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
