Abstract
The utility model relates to an artificial nest for freshwater shrimps. The artificial nest comprises small steel rings, large steel rings, a foam floater, meshes, pebbles and a bottom mesh, wherein a plurality of small steel rings and a plurality of large steel rings are arranged in a multi-group concentric manner in a sequence of one small steel ring and one large steel ring from top to bottom and connected through the meshes to form a lantern shape; the large steel ring at the bottom is bound by the bottom mesh; the pebbles are arranged on the bottom mesh; and the foam floater is arranged inside the mesh at the top. The artificial nest is in the lantern shape, the surface of the artificial nest is made of the meshes, and the freshwater shrimps can climb and adhere to the meshes, so that the adhesion area of the freshwater shrimps in water is expanded, and the aquaculture output of the freshwater shrimps is increased; the artificial nest can be compressed and folded, so that the storage space of the artificial nest is reduced in non-aquaculture seasons.
Description
Technical field
The utility model relates to aquaculture tool field, particularly the artificial nest of a kind of pond crayfish.
Technical background
Pond crayfish belongs to Palaemonidae, also claims Malaysian prawn, gold thread shrimp, the long-armed shrimp of fresh water etc., originates in the Indian Ocean, torrid areas, the Pacific Ocean, moves in fresh water or salty freshwater.Compared with domestic other shrimps in culture, that pond crayfish has is individual large, feeding habits assorted, growth fast, be easy to cultivation, meat is good, to advantages such as feed nutrition requirement are low, is the economic shrimps of the important aquatic products of current China.
Pond crayfish is the aquatic crustacean that dwelling property of a kind of end is climbed up by holding on to, in water bottom life, more in adherance place gatherings such as pasture and water, while propagating artificially, because water bottom mud is more, climbs up by holding on to nowhere, often causes yield reducation.At present, the artificial shrimp nest often using, is all generally to form with materials processings such as branch or water peanuts, and their service life is short, easily affects the growth of pond crayfish in rotten process.
Utility model content
The purpose of this utility model is to provide the artificial nest of a kind of pond crayfish, solves in pond crayfish breeding process and climbs up by holding on to nowhere, causes the problem of yield reducation.
The utility model solves the technical scheme that its technical problem adopts: the artificial nest of this pond crayfish, comprise drum rim, large steel ring, foam plastic float, net sheet, stone, bottom web sheet, it is characterized in that: multiple drum rims and multiple large steel ring are organized concentric by the order that is followed successively by from top to bottom drum rim, large steel ring more and arranged, and connect into bird-caging with net sheet, bottom web sheet bondage for the large steel ring of bottommost, stone is placed on bottom web sheet, and foam plastic float is placed in the net sheet of the top.
Preferably, described drum rim diameter is 10～15cm.
Preferably, described large steel ring diameter is 50～60cm.
Preferably, described drum rim and large steel ring adjacent height when artificial nest launches are completely 25～30cm.
Preferably, described net sheet and bottom web sheet are the polythene net sheet of mesh 0.5～1cm.
The utility model compared to the prior art, have the following advantages and effect: the artificial nest of a kind of pond crayfish of the utility model becomes bird-caging, surface is net sheet, and pond crayfish can climb up by holding on to and adhere in the above, expand the bond area of pond crayfish in water body, improved the cultured output of pond crayfish.This artificial nest is compressible folding, in non-cultivation season, has reduced the parking space of artificial nest.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. drum rim, 2. foam plastic float, 3. large steel ring, 4. net sheet, 5. stone, 6. bottom web sheet.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
As shown in Figure 1, the artificial nest of a kind of pond crayfish of the present embodiment, comprise drum rim 1, large steel ring 3, foam plastic float 2, net sheet 4, stone 5, bottom web sheet 6, multiple drum rims 1 and multiple large steel ring 3 are organized concentric by the order that is followed successively by from top to bottom drum rim 1, large steel ring 3 more and are arranged, and connect into bird-caging with net sheet 4, large steel ring 3 use bottom web sheet 6 bondages of bottommost, stone 5 is placed on bottom web sheet 6, and foam plastic float 2 is placed in the net sheet 4 of the top.Preferably, select three drum rims 1 and three large steel rings 3, drum rim 1 diameter is 10～15cm, and large steel ring 3 diameters are 50～60cm, artificial nest while launching completely the height of adjacent drum rim 1 and large steel ring 3 be 25～30cm.While launching completely, artificial nest total height is 1.25～1.50m, and this is highly just close to pond crayfish culturing pool height (current common pond crayfish culturing pool height is all within the scope of 1～1.5m).Net sheet and bottom web sheet are the polythene net sheet of mesh 0.5～1cm, are beneficial to pond crayfish and climb up by holding on to and perch.
During use, the gravity of dependence stone 5 relies on the buoyancy of foam plastic float 2 that artificial nest is launched completely at the bottom of artificial nest bottom is placed in to culturing pool pond, and large as far as possible bond area is provided, pond crayfish can climb up by holding on to and adhere on net sheet 4, has improved the cultured output of pond crayfish.
In non-cultivation season, do not need to use the artificial nest of pond crayfish, the volume compression that the screen cloth of artificial nest can be launched is folding, and the space between adjacent drum rim 1 and large steel ring 3 is compressed, reduces storage space.
Above content described in this specification is only to the explanation of the utility model example.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment; only otherwise depart from the content of the utility model specification or surmount this scope as defined in the claims, all should belong to protection domain of the present utility model.
Claims (5)
