Abstract
The patent of the utility model discloses a red chelonian fry trapping device, concretely relates to breeding device's technical field. The device for trapping the seedlings of the red crayfish comprises a plurality of horizontal supporting plates which are longitudinally arranged at intervals, vertical supporting plates are inserted between every two adjacent horizontal supporting plates at equal intervals, and a groove which is positioned between the two adjacent vertical supporting plates is further formed in each horizontal supporting plate. Adopt the utility model discloses technical scheme has solved the big problem of current fishing mode to the shrimp seedling injury, can be used to the seizure of shrimp seedling.
Description
Technical Field
The utility model relates to a breeding device's technical field, in particular to red chelonian fry trapping device.
Background
Red swamp crayfish (Cherax aquaticarinatus) belongs to the order Decapoda, the family Paracamidae (Paratacidae), the genus red swamp crayfish (Cherax), weighs up to about 600g in maximum individuals, and is one of the most famous and expensive freshwater shrimps in the world. The shrimps live in fresh water, have the advantages of high growth speed, strong adaptability, weak aggressivity, poor feeding quality, low oxygen resistance and the like, can be naturally propagated in ponds or paddy fields, can reach 50-150 g in individual specification after artificial cultivation for 5-6 months, and are excellent fresh water cultivation varieties. In recent years, people in many industries aim at the red crayfish, the fry breeding and adult shrimp breeding technologies are greatly improved, the consumption market is gradually formed, and the red crayfish industry develops into a fast lane. At present, the main culture areas in China are expanded from the original three areas of long triangle, bead triangle and Fujian to the areas of south China, China and east China, and the culture situation is actively developed nationwide.
In the actual shrimp fry catching operation, the used catching device generally adopts catching tools such as a pull net and a dip net, but in the process of using the pull net and the dip net, the catching efficiency is low, the labor intensity is high, and the damage to the shrimp fries is large.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a red chelonian fry trapping device has solved the big problem of current mode of catching injury to shrimp fry.
In order to achieve the above purpose, the technical scheme of the utility model is as follows: the device for trapping the seedlings of the red crayfish comprises a plurality of horizontal supporting plates which are longitudinally arranged at intervals, vertical supporting plates are inserted between every two adjacent horizontal supporting plates at equal intervals, and a groove which is positioned between the two adjacent vertical supporting plates is further formed in each horizontal supporting plate.
Furthermore, each equal interval is opened on recess and the vertical support plate has a plurality of water holes of crossing, every it all is equipped with the filter screen on the water hole to cross.
Through the arrangement, when the device is put forward to a culture pond, the situation that the shrimp seeds in the device are brought out by water flow due to the fact that water between every two vertical supporting plates is only gushed from the front side and the back side is avoided, and the capturing efficiency of the shrimp seeds is improved.
Furthermore, the front side and the rear side of the horizontal supporting plates are detachably connected with a screen.
Through the setting, the condition that the shrimp larvae in the device are prevented from escaping can be played by utilizing the screen, and meanwhile, the shrimp larvae can be screened by utilizing the screens with different mesh sizes.
Compared with the prior art, the beneficial effect of this scheme:
this scheme materials are simple, raw and other materials obtain easily, have reduced the cost of this device, utilize horizontal support plate and vertical support plate to enclose the hole that closes formation simultaneously and simulate the nest of shrimp seedling to realize the contactless of shrimp seedling and traped, avoided the damage that seizure in-process shrimp seedling produced.
Drawings
FIG. 1 is a schematic structural view of a device for trapping the fry of the crayfish of the present invention;
fig. 2 is a schematic structural view of a crayfish offspring seed trapping device (without a screen) in this embodiment.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments:
reference numerals in the drawings of the specification include: horizontal support plate 1, vertical support plate 2, couple 3, screen cloth 4.
Examples
As shown in figures 1 and 2: the utility model provides a red chelonian fry trapping device, including the vertical horizontal support plate 1 that sets up in a plurality of equidistance intervals, horizontal support plate 1's quantity is six in this embodiment, a plurality of inserting grooves have been seted up to every horizontal support plate 1's top and the equal interval equidistance in bottom, it has vertical support plate 2 to peg graft between every two inserting grooves that correspond from top to bottom, the plastic slab is all chooseed for use to vertical support plate 2 and horizontal support plate 1's material, thereby the acquisition degree of difficulty of raw materials has been reduced, be favorable to reducing the manufacturing cost and the processing degree of difficulty of this device. Every horizontal support plate 1's top still is equipped with the recess that is located between two adjacent vertical support plate 2, and the degree of depth of every recess is located to center department by both sides around and increases gradually, and impartial apart from opening has a plurality of water holes of crossing on every recess and the vertical support plate 2, all is equipped with the filter screen on every water hole of crossing, and equal symmetry is equipped with four couples 3 on four angles of two horizontal support plate 1 front and back both sides that are located top and bottom, is connected with screen cloth 4 on four couples 3 with one side jointly.
The working process of the scheme is as follows: when the device is used for capturing the shrimp seeds of the red crayfish, the device is firstly placed in a shrimp seed culture pond, the holes formed by enclosing the vertical support plates 2 and the horizontal support plates 1 are used for simulating the nests of the shrimp seeds, the sizes of the holes in the device can be adjusted according to the specifications of the shrimp seeds, and therefore the shrimp seeds can be captured by the holes. After the shrimp seeds enter the holes, the screen 4 is hooked by the hooks 3, so that the front side and the rear side of the horizontal support plate 1 are sealed, and the condition that the shrimp seeds are taken away due to the fact that water in the device rushes out when the device is taken out is avoided; meanwhile, the caught shrimp seeds can be screened by using the screens 4 with different meshes, so that the catching effect is improved. At the in-process that promotes this device, utilize the recess and cross the water hole and can avoid the water in this device once only from the condition of preceding back both sides outflow fast, be convenient for with the shrimp postlarvae gathering in the recess.
The above are merely examples of the present invention, and common general knowledge of known specific structures and/or characteristics of the embodiments is not described herein in an excessive amount. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent. The scope of the claims of the present application shall be determined by the contents of the claims, and the description of the embodiments and the like in the specification shall be used to explain the contents of the claims.
