Abstract

The utility model relates to a loach fry device, in particular to a loach spawning bed. The loach spawning bed comprises a box body and a spawning net, wherein a water inlet and a water outlet are formed in the box body, the spawning net is of an arc-shaped structure, a loach fixing net is arranged on the spawning net, and a stretchy opening is formed in the loach fixing net. According to the technical scheme, the loach spawning bed has the advantages that due to the fact that the loach fixing net is adopted to fix loaches, after spawning, it can be ensured that a loach parent body can not eat loach spawns, a cotton net is adopted as the spawning net, the loaches can not be damaged in the spawning process, the comfort degree is high, and the higher spawning rate is ensured; an oxygenation pump is mounted, and a sand filter exhaust nozzle is adopted by the oxygenation pump, so that the oxygen can be dissolved in water better , and the dissolved oxygen in the water is increased. The loach spawning bed is simple in structure, convenient to operate and low in manufacturing cost.

Description

A kind of loach bed of laying eggs

Technical field

The utility model relates to loach fry device, especially a kind of loach bed of laying eggs.

Background technology

Loach has higher nutritive value, in recent years, along with the increase of international market demand amount, has now become the famous-brand and high-quality kind of the good fresh water of cultivation prospect.

Expansion along with loach breeding scale, demand to loach seed increases considerably, seed has become the main restricting factor that can loach breeding scale expand, how to improve fertilization rate and incubation rate that loach parent produces loach ovum, reducing damage is its key point, in existing loach modes of reproduction, mainly contain two kinds of methods of artificial insemination and natural spawning, and because loach individuality is less, epidermal mucus is many, therefore carry out test-tube labour intensity larger, and very large to the damage of loach parent in operating process, very easily cause loach parent dead postpartum, therefore, for the seed of propagating artificially, be mainly by the natural mating of loach parent at present, natural spawning obtains.But the scope of activities of existing loach equipment for breeding loach is excessive, cause loach mating and fertilization rate to reduce, and traditional loach equipment for breeding fertilized egg is in bottom of device, collect fertilized egg inconvenient, during collection, also easily ovum is injured, reduce its survival rate, simultaneously due to after loach parent lays eggs, under hungry situation, the loach ovum of can eating, must adopt spacer assembly that loach parent and ovum are separated.

At present loach breeding field adopts the loach bed of laying eggs, generally that loach parent is directly placed on the oophyte filtering layer of culturing pool, the oophyte that parent is given birth to is thrown on oophyte filtering layer, the obstetric table of this structure, parent can be eaten up a lot of oophytes equally between the egg-laying period, cause oophyte quantity to reduce, economic benefit is low.

Summary of the invention

The technical problems to be solved in the utility model is: overcome deficiency of the prior art, a kind of loach simple to operate, easy to use bed of laying eggs is provided.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:

The loach bed of laying eggs, comprises casing and the net of laying eggs, and offers water inlet and delivery port on described casing, described in the net of laying eggs be arcuate structure, described in lay eggs and have loach fixed network on the net, described loach fixed network has individual telescopic mouth.

Further, the net of laying eggs described in is cotton gauze.

Further, the Netcom of laying eggs described in crosses bail and is fixed on casing.

Further, dismountable being arranged on of described loach fixed network laid eggs on the net.

Further, in described casing, oxygen pump is installed, the appendix of described oxygen pump, by two bronchies, is provided with sand filtration stone exhaust nozzle on described bronchi.

Adopt the beneficial effect of the technical solution of the utility model to be: the utility model is owing to adopting loach fixed network that loach is fixed, after laying eggs, can guarantee that loach parent can practical loach ovum, the net of laying eggs adopts cotton gauze, loach can not come to harm in the process of laying eggs, level of comfort is high, guarantees higher spawning rate; And oxygen increasing pump is installed, oxygen increasing pump adopts sand filtration stone exhaust nozzle to increase the dissolved oxygen amount in water so that oxygen is dissolved in the water better, of the present utility model simple in structure, easy to operate, low cost of manufacture.

Accompanying drawing explanation

Fig. 1 be loach of the present utility model lay eggs bed structural representation.

In figure, 1 is water inlet, and 2 is delivery port, and 3 is casing, and 4 is the net of laying eggs, and 5 is bail, and 6 is fixed network, and 7 is oxygen increasing pump, and 8 is bronchi

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described further.

As shown in Figure 1, the loach bed of laying eggs, comprises casing 3 and the net 4 of laying eggs, and offers water inlet 1 and delivery port 2 on described casing 3, the described net 4 of laying eggs is for arcuate structure, adopt this structure, can avoid loach to throw from laying eggs on the net, described in lay eggs on net 4 and have loach fixed network 6, described loach fixed network 6 has individual telescopic mouth, adopt this structure, loach can be fixed in certain area, avoid the loach loach ovum of eating.

Further, for fear of loach, when laying eggs, come to harm, described in lay eggs net 4 for cotton gauze, cotton gauze quality is soft, can allow comfortable the laying eggs of loach.

Further, for convenient net disassembly, cleaning or the repair operation of laying eggs, described in the net 4 of laying eggs by bail 5, be fixed on casing 3, by the bail net of fixedly laying eggs, can reduce the damage of netting laying eggs.

Further, in order to extract more easily loach ovum, dismountable being arranged on of described loach fixed network 6 laid eggs on net 4.

Further, in order to guarantee the dissolved oxygen amount in water, in described casing 3, oxygen pump 7 is installed, the appendix of described oxygen pump 7 is by two bronchies 8, sand filtration stone exhaust nozzle is installed on described bronchi 8, by sand filtration stone exhaust nozzle, air can be become to tiny bubble, increase the dissolved oxygen amount in water.
