Description
Technical Field
The utility model relates to the field of aquaculture devices, in particular to a young puffer fish separating device.
Background
In the cultivation process of the puffer green fries, in order to reduce mutual food residue among individuals and prevent large individuals from attacking small individuals, the fries need to be separated regularly, namely, the large individuals and the small individuals need to be screened and then are separated into pools for cultivation. The existing seedling separation method is to use screens with different apertures for manual screening. The existing method has 2 defects, firstly, a method for inducing larva clusters is lacking, and only a small number of individuals can be fished out for each screening; the second is that the screening process is liable to cause the damage to the larva, and first dorsal fin of juvenile fish head is the hard thorn that can erect, and in the manual screening process, the individual is passive outflow screen cloth, and hard thorn hangs easily on the screen cloth, and then causes the damage. Therefore, it is important to develop a seedling separation device that can induce the juvenile fish to cluster and allow individuals to naturally swim out of the screen.
The utility model comprises the following steps:
the utility model provides a young fish separating device for puffer green, which induces young fish clusters through baits to enable young fish to freely enter and exit sieve holes, reduces individual damage and further completes the seedling separating work.
The utility model is completed according to the following operation technology:
the utility model provides a young fish of green fin puffer fish divides seedling device, includes cursory, divides seedling screen cloth, bait pocket and collects the string bag, cursory connection in the top that divides the seedling screen cloth, divides the seedling screen cloth to become the hollow hemisphere of back-off, and the bait pocket passes through rope form thing to be connected inside dividing the seedling screen cloth, divides seedling screen cloth below to connect and collects the string bag, and it is the round platform bodily form of inversion to collect the string bag, and the big mouth of collecting the string bag is connected on dividing the opening of seedling screen cloth.
Further, the seedling separating screen is made of hard materials, and the mesh of the screen is determined according to the specification of seedlings to be separated.
Further, the small opening at the lower end of the collecting net bag is a telescopic opening and is used for discharging the collected larvae.
The using method of the device comprises the following steps: bait such as minced fillet, minced shrimp and the like is put into the bait net bag, and the opening is fastened. The lower end opening of the collecting net bag is fastened, the seedling separating device is placed into the seedling cultivating pool, the floats are on the water surface, and the rest parts are immersed in water. Under the attraction of the bait, larvae start to gather, and only individuals with smaller sizes can enter the device due to the presence of the seedling separating screen. When the larvae in the device reach a certain quantity, the device is slowly lifted until the lower end of the collecting net bag leaves the water surface, and a large amount of larvae are collected in the net bag. The device is moved to the upper part of the new pool, the opening of the lower end of the collecting net bag is opened, and the juvenile fish can be transferred into the new pool, so that the seedling separation is completed.
Compared with the prior art, the utility model has the beneficial effects that: in the prior art, when the young fish is separated, a method for inducing the young fish to cluster is lacked, the separating efficiency is low, and the young fish is easy to be injured in the separating and screening process. According to the seedling separating device, young fish clusters are attracted through the baits, so that the seedling separating efficiency is improved; in the screening process, young fish can freely enter and exit the sieve pores, so that loss of the young fish is not easy to occur, and the survival rate of separated seedlings is improved.
Drawings
Fig. 1 is a schematic structure diagram of the device of the utility model, 1, a buoy, 2, a seedling separating screen, 3, a bait net bag, 4 and a collecting net bag.
Detailed Description
The technical scheme of the present utility model is further explained by examples below, but the scope of the present utility model is not limited in any way by the examples.
Example 1: the utility model provides a young fish of green fin puffer, as shown in fig. 1, including cursory 1, divide seedling screen cloth 2, bait pocket 3 and collect string bag 4, cursory 1 connects in the top that divides seedling screen cloth 2, divides seedling screen cloth 2 to become the hollow hemisphere type of back-off, and bait pocket 3 passes through the rope form to be connected inside dividing seedling screen cloth 2, divides seedling screen cloth 2 below to connect and collect string bag 4, and collect string bag 4 is the round platform bodily form of inversion, and the big mouth of collecting string bag 4 is connected on dividing the opening of seedling screen cloth 2.
The buoy 1 is disc-shaped or cylindrical, is made of hollow plastic material, floats on the water surface, and is connected with the seedling separating screen 2 below through a connecting rope made of 10cm nylon material. The seedling separating screen 2 is a hollow hemispherical shape, the radius is 30cm, the opening is oriented, the surface is provided with screen holes, and the size of the screen holes is selected according to the size of young fish. The bait net bag 3 is connected right above the seedling separating screen 2 through nylon strings, the length of the strings is 40cm, the bait net bag 3 is made of nylon, one end of the bait net bag is open, and the bait net bag is provided with a telescopic opening of an annular rope. The collecting net bag 4 is made of nylon and is in an inverted truncated cone shape, the height is 30cm, the edge of a large opening at the upper end is connected with the opening of the seedling separating screen 2, and the radius of the large opening is 30cm; the lower end is opened, provided with a telescopic opening of an annular guy rope, with the radius of 8cm, and used for discharging the collected larvae.
The using method of the device comprises the following steps: bait such as minced fillet, minced shrimp and the like is put into the bait net bag 3, and the opening of the bait net bag 3 is fastened. The lower end opening of the collecting net bag 4 is fastened, the seedling separating device is placed into a seedling cultivating pool, the buoy 1 floats on the water surface, and the rest parts are immersed in water. Under the suction of the bait, the larvae start to gather, and only individuals with smaller sizes can enter the device due to the presence of the seedling separating screen 2. When the larvae in the device reach a certain quantity, the device is slowly lifted until the lower end of the collecting net bag 4 leaves the water surface, and a large quantity of larvae are collected in the net bag. The device is moved to the upper part of the new pool, the opening of the lower end of the collecting net bag 4 is opened, and the juvenile fish can be transferred into the new pool, so that the seedling separation is completed.
