The spawning device for South America white shrimps comprises a fixed frame, wherein each surface of the fixed frame is covered by a nylon net to form a spawning box, a plurality of floating balls are arranged at the top of the spawning box, four vertex angles of one side surface of the spawning box are connected with a wide-neck shrimp inlet net, a plurality of unidirectional shrimp inlets are formed in the nylon net on the side surface, and a shrimp outlet is formed in the other side surface of the spawning box; the bottom of the spawning box is communicated with a detachable spawn receiving slot; a 100-mesh boulting cloth mesh bag is arranged in the detachable spawn receiving slot. The spawning device for South America white shrimps can avoid pains of spawning parent shrimps in pool transferring and siphon water changing processes, stress reaction of the parent shrimps is alleviated, a safe and stable environment is provided for mating and spawning of the parent shrimps, a spawn collection rate is increased, and the breeding yield and quality are guaranteed.
Description
Technical field
The utility model relates to aquaculture device technical field, particularly a kind of device of laying eggs of Penaeus Vannmei.
Background technology
Penaeus Vannmei is one of three large shrimps that world today's cultured output is the highest.Its delicious meat, processing dressing percentage can be up to 67%, and suitable temperature range is wide, can be 18～32 ℃ of growth, suitable salt scope is also wide, can under salinity 1～40% condition, grow, be a kind of good desalination cultivation kind.Penaeus Vannmei growth is fast, and resistance against diseases is strong, becomes gradually the main cultivation shrimp species of south China, and favourable Hai Min increases income.In the breeding process of Penaeus Vannmei, good control parent shrimp breeding condition, promotes lay eggs and collect the key link that fertilized egg being affects cultured output and quality.At existing culture of Penaeus vannamei technology Prawn, laying eggs is parent shrimp to be transferred to spawning pond lay eggs substantially, in mobile process, is difficult to avoid parent shrimp is damaged, and affects it and lays eggs, and further affected the quantity and quality of cultivation.
Utility model content
The purpose of this utility model is to provide a kind of device of laying eggs of Penaeus Vannmei, overcome needs that parent shrimp is transferred to spawning pond and lays eggs in existing culture of Penaeus vannamei technology, parent shrimp can come to harm in transfer process, and then affect the defect of cultured output and quality, parent shrimp can be provided from while providing a kind of South America prawn to lay eggs and fall the hardship that pond and siphon change water, the device of laying eggs compared with safety and stability environment is provided to parent shrimp mate and oviposit.
In order to reach above-mentioned object, the utility model adopts following concrete technical scheme: a kind of device of laying eggs of Penaeus Vannmei, comprise fixed frame, each face of described fixed frame is covered and is formed the case of laying eggs by nylon wire, the described box top of laying eggs is provided with some ball floats, four drift angles of the described side of case of laying eggs connect broad mouth type and enter shrimp net, and the nylon wire of described side is provided with some unidirectional shrimp-entering mouths, and the case another side of laying eggs is provided with out shrimp mouth; The described case bottom of laying eggs communicates with the detachable ovum groove that connects.
Described detachable connecing in ovum groove is provided with bolting silk mesh bag, and the mesh size of described bolting silk mesh bag is 100 orders.
Use principle of the present utility model is: the egg-laying period, in nursery pond, parent shrimp is caught up with into broad mouth type and enters shrimp net, parent shrimp enters by unidirectional shrimp-entering mouth the case of laying eggs, parent shrimp lays eggs in the case of laying eggs, the detachable ovum groove that connects is collected fertilized egg, after shrimp lays eggs, only need the detachable ovum groove that connects to leave the water and can collect shrimp ovum, and open out shrimp mouth and just can allow the complete shrimp that lays eggs swim out of.
Compared with prior art, the utility model can be removed from when parent shrimp lays eggs, falling pond and siphon and changing the hardship of water, and has reduced the stress reaction of parent shrimp, safer stable environment is provided to parent mate and oviposit, improve collection ovum rate, guaranteed the quantity and quality of cultivation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment
in order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.
