Abstract
An intensive spawning device for preventing parental loaches from damaging fertilized eggs comprises a box body. The intensive spawning device for preventing the parental loaches from damaging the fertilized eggs is characterized in that the box body comprises a mating spawning box and an egg collecting box, wherein a loach inlet is arranged on the upper portion of the mating spawning box, a mash piece is arranged at least on the lower portion of the mating spawning box, the size of mesh formed on the mesh piece is big enough for the eggs to pass through but not big enough for the parental loaches to pass through, a spawning support which is arranged inside the egg collecting box is further arranged on the lower portion of the mating spawning box, a water inlet pipe with a water inlet valve is arranged on the upper portion of the egg collecting box and an egg outlet pipe with an egg outlet valve is arranged on the lower portion of the egg collecting box. The overall structure of the intensive spawning device for preventing the parental loaches from damaging the fertilized eggs is more reasonable and practical, and thus swallow and damage to the fertilized eggs by the parental loaches can be avoided.
Description
Technical field
The utility model relates to aquaculture field, especially a kind of intensive device of laying eggs of the novel parent of preventing loach damage fertilized egg.
Background technology
Loach is under the jurisdiction of Cypriniformes, Cobitidae, and loach belongs to.It distributes wide, and strong adaptability is the small-sized economic freshwater fish of a kind of omnivorousness.The loach delicious meat has higher nutritive value and medical value, deeply is subjected to liking of domestic and international consumer, is the traditional exporting of China.Loach has the good reputation of " ringdove in the sky, on the ground loach " in China, also have the laudatory title of " ginseng in the water ".Adaptive capacity is very strong in the adverse circumstances that loach is low in some oxygen content, water quality is relatively poor, is a kind of low-carbon (LC) breed variety that very large productive potential are arranged.Because ecotope is destroyed, loach natural seeding, wild fry quantity can not be supplied with cultivation effectively but in recent years.Various places are carried out cement pit artificial breeding, net cage seedling nursery or seedling rearing in earth ponds one after another, for alleviating in short supply the playing an important role of China loach seed.
Existing a kind of patent No. is that utility model that the CN200810021131.2 name is called " a kind of loach seedling cultivation technology " has just related to this method of net cage seedling nursery in above-mentioned three kinds of methods.
Growing seedlings of these three kinds of methods all is that in the process of laying eggs, the fertilized egg of output and parent loach are in same space with the loach rear mate and oviposit of hastening parturition, loach lay eggs from evening 10 up to 8 o'clock the next mornings needs continue 10 hours.Study discovery according to us, the parent loach is in starvation postpartum, every loach about 150 ovum of per hour can ingesting, and the ingest quantity of ovum of 10 hours every parent loach reaches 1500 between the egg-laying period, and is very surprising.In addition, the parent loach be because its mating activity acutely also can damage fertilized egg in the same space in a large number, thereby causes hatchability of fertile eggs to reduce by 15%, and the abnormal rate of loach seedling reaches 4.7%, has a strong impact on the quality of loach seed.
Therefore the loach that is necessary very much the to design a kind of special use facility of laying eggs reduces the parent loach to the eating and damaging of fertilized egg, and improves the incubation rate of fertilized egg, reduces the abnormal rate of loach seedling.Utilize simultaneously this facility can carry out that loach is intensive to lay eggs, increase substantially the quantity of laying eggs with batch loach.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of can prevent that the parent loach is to the intensive device of laying eggs that prevents parent loach damage fertilized egg of eating and damaging of fertilized egg for above-mentioned technology existing issue.
The technical scheme that the utility model addresses the above problem is: a kind of intensive device of laying eggs of the parent of preventing loach damage fertilized egg, it comprises casing, be characterised in that: described casing comprises mate and oviposit case, egg-collecting box, described mate and oviposit upper box part is provided with fish inlet, at least the bottom is provided with the net sheet, and the size of the formed mesh of net sheet can make ovum by the parent loach can not be passed through, and the bottom of described mate and oviposit case also is provided with the support of laying eggs, and it is installed in the egg-collecting box; The top of described egg-collecting box is provided with the water inlet pipe with inlet valve, and the egg-collecting box bottom is provided with the ovijector with the ovulation valve.
As improvement, each face of described mate and oviposit case all is provided with the net sheet, and the formed mesh of net sheet of bottom is greater than the mesh of other each faces.
As improvement, described mate and oviposit case also has stainless steel insert, and the upper limb middle part of stainless steel insert is provided with draw ring.
As improvement, described egg-collecting box bottom is provided with 4% to 6% gradient from water inlet to the ovulation end.
As improvement, described egg-collecting box is provided with the gas tube with charging valve, and the bottom of gas tube is provided with gas charging stone.
As improvement, described gas tube is 4.
Compared with prior art, the utility model is a little: because the stainless steel insert upper limb of mate and oviposit case middle part is provided with draw ring, and the top of mate and oviposit case is provided with fish inlet, conveniently allow the parent loach of injection behind the oxytocic hormone pour in the case of laying eggs from this, carry out mate and oviposit, after loach laid eggs, two staff were grabbed draw ring and are carried away the case of laying eggs, and poured out loach after laying eggs by fish inlet; Because the bottom at egg-collecting box arranges 4% to 6% gradient from water inlet to the end of ovulating, during with the assurance ovulation, allow fertilized egg thoroughly discharge clean from ovijector with current; The egg-collecting box bottom is provided with the gas tube of dispersion in addition, the upper end of gas tube is provided with gas charging stone, give on the one hand the parent loach oxygenation of the case of laying eggs, allow on the other hand the fertilized egg of bottom has sufficient dissolved oxygen in the egg-collecting box, overall structure is more reasonable and practical, can prevent the eating and damaging fertilized egg of parent loach.
