Abstract
The utility model discloses a cuttlefish spawning device. The cuttlefish spawning device comprises a bracket, a string and a mesh; the bracket is knitted by plastic sleeved metal wires; a sawn nylon mesh with the mesh size of 1cm*1cm is arranged in the bracket; the string is connected to the frame of the bracket; the bracket is vertically suspended in water in a spawning pond by the string; and the device can be adjusted up and down optionally by using the string. The device is simple in structure, flexible to use and not likely to damage, can be recycled repeatedly, and is conductive to culturing cuttlefish germ cells and offspring seeds in large scale.
Description
Technical field
The utility model relates to technical field of aquaculture, particularly a kind of inkfish spawning device.
Background technology
Cuttlefish, especially Sepiella maindroni are the important economic fish resources of China, are one of traditional " four large marine products ", and very high output was once arranged in history, and its delicious meat is nutritious, is loved by the people.But since mid-term, due to overfishing and environmental condition, caused the cuttlefish resource to suffer great destruction from 20 century 70s, be tending towards already exhausted.From the eighties in 20th century, begin to carry out the scale aquaculture technical research and development stage.At natural waters, the attachment of laying eggs of cuttlefish is mainly gorgonian, but at present by artificial destruction.Therefore, recover cuttlefish output, need a kind of man made attachment apparatus, as natural waters inkfish spawning attachment with propagate the inkfish spawning attachment artificially.Utilize plant as inkfish spawning adherance material, wide material sources, cost is low, simple for production, adhesion effect is better, but the plant attaching base is easily damaged in transportation and launch process, and it is poor to be cycled to repeat usability.
The utility model content
In order to overcome above shortcomings part in prior art, the purpose of this utility model is to provide a kind of inkfish spawning device, and this apparatus structure is simple; use flexibly; not fragile, can be cycled to repeat use, be conducive to large-scale cultivation cuttlefish fertilized egg and seed.
In order to reach above-mentioned purpose, the utility model adopts following concrete technical scheme: a kind of inkfish spawning device, consisted of by carriage, cord, net sheet, carriage is by the metal wire knitted of plastic sheathed, it is the nylon mesh sheet of making of 1 * 1cm that mesh is housed in carriage, cord is connected on the carriage frame, and cord in spawning pond water, can arbitrarily be adjusted device the carriage vertical hanging by cord up and down.
Compared with prior art, the utlity model has following outstanding advantages and effect:
1, this device is conducive to male cuttlefish secretion property excreta on laying nest, induces female inkfish spawning and adheres to, and is conducive to the male and female parent and jointly protects output be attached to the fertilized egg of laying nest and carry out spraying-rinsing with funnel to the fertilized egg ovum in pairs.
2, this device is convenient to hang in spawning pond, the number that the cuttlefish colony of can be flexibly laying eggs according to participation and egg production peak time thereof arrange the laying nest magnitude setting, being conducive to cuttlefish lays eggs round the clock, after being covered with fertilized egg, the net sheet can be taken out laying nest, move into the hatchery after sterilization, simultaneously more renew the net sheet, allow parent continue to lay eggs and adhere to.
3, in the incubating oosperm process, can by rocking gently the net sheet, can remove dirt and the dead ovum that adheres on the net sheet, be conducive to large-scale cultivation cuttlefish fertilized egg and seed.
Description of drawings
Fig. 1 is structural representation of the present utility model;
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
as shown in Figure 1, a kind of inkfish spawning device, by carriage 1, cord 2, net sheet 3 consists of, carriage 1 is by the metal wire knitted of plastic sheathed, what mesh is housed is 1 * 1cm in carriage 1 makes nylon mesh sheet 3, cord 2 is connected on carriage 1 frame, cord with the carriage vertical hanging in spawning pond water, device arbitrarily can be adjusted up and down by cord, this device is conducive to male cuttlefish secretion property excreta on laying nest, induce female inkfish spawning and adhere to, being conducive to the male and female parent protects output be attached to the fertilized egg of laying nest and carry out spraying-rinsing with funnel to the fertilized egg ovum in pairs jointly, the number that the cuttlefish colony of can be flexibly laying eggs according to participation and egg production peak time thereof arrange the laying nest magnitude setting, being conducive to cuttlefish lays eggs round the clock, after being covered with fertilized egg, the net sheet can be taken out laying nest, move into the hatchery after sterilization, more renew simultaneously the net sheet, allowing parent continue to lay eggs adheres to, in the incubating oosperm process, can be by rocking gently the net sheet, can remove the dirt and the dead ovum that adhere on the net sheet, be conducive to large-scale cultivation cuttlefish fertilized egg and seed.
It should be noted that at last: above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
