Abstract
The invention relates to a coldwater fish high-density hatcher which comprises a hatching trough, hatching boxes, a water inlet tube and a water outlet tube, wherein the hatching boxes are arranged in the hatching trough side by side, and the water inlet tube and the water outlet tube are communicated with the hatching trough; the water inlet tube and the water outlet tube are respectively arranged at the front end and tail end of the hatching trough; the bottom plate of each hatching box is provided with permeable holes, and the rear side plate of each hatching box along the water flow direction is provided with water outlet holes and a hatching box baffle fixedly connected with the hatching box; and each hatching box is internally sleeved with a sieve tulle. The coldwater fish high-density hatcher has simple structure and low construction cost, can carry out high-density hatching, occupies small production space, saves energy, is easy to manage and is simple and convenient to operate; 500-1000 g of oosperms can be placed in each hatching trough; and 5-year experiments prove that the hatching rate is above 70%, and the average hatching rate of the oosperms can be more than 85% when the weight of the oosperms in each box is 700-800 g.
Description
Technical field
The present invention relates to a kind of cold water fish high density incubator.
Background technology
Cold water fish need low temperature in the fertilized egg hatching process, so brooding time is longer, the longest reaching more than 40 days because of its unique reproductive physiology characteristic.Traditional cold water fish incubator adopts the hatching of cement pit flowing water more or adopts funneling bath hatching.The cement pit incubator takes up room greatly, and not easy to operate and observation easily forms the dead angle, and long-time hatching can make incubation rate obviously reduce; Funneling swash of wave water hatching disease control is not easy to operate and hatching density is little; The common ground of the two is that the difficulty of emerging is big, and it is bigger to consume energy.
Summary of the invention
The purpose of this invention is to provide a kind of hatching density height, take workshop space cold water fish incubator little and easy and simple to handle.
The technical solution adopted in the present invention is as follows:
The present invention includes incubation tank, be arranged on the incubator box that is arrangement arranged side by side in the incubation tank and and the incubation tank water inlet pipe and the outlet pipe that are connected, described water inlet pipe and outlet pipe are separately positioned on the head end and the end of incubation tank, the base plate of described incubator box is provided with permeable hole, incubator box is provided with apopore along the back side panel of water (flow) direction, incubator box is provided with the incubator box baffle plate of fixedlying connected with incubator box along the back side panel of water (flow) direction, is set with the bolting silk net of selecting the order number according to the diameter of fertilized egg in the incubator box.
The diameter of described permeable hole and apopore is 3 ~ 5 mm.
Distance between the described incubator box is 10 ~ 15 cm.
Described incubator box uses lanyard on incubation tank.
The beneficial effect that the present invention obtains is: the present invention has absorbed traditional fish flowing water hatching principle, and its maximum characteristics are to be fit to the long cold water fish of brooding time, as lawver, pike, rainbow trout, brachymystax lenok etc.The present invention is in the flowing water hatching process, and the incubator box baffle plate on the incubator box back side panel contacts with bottom land tightly with the incubation tank inwall, and current are tackled, make recoil stirring fertilized egg on the current direction, both can prevent adhesion between the fertilized egg, and can increase the dissolved oxygen in the water again, improve incubation rate greatly.The present invention is simple in structure, and cost is low, can carry out the high density hatching, and it is little to take the production space, energy savings, and manageability, easy and simple to handle.Each incubation tank can be put fertilized egg 500 ~ 1000 g, and all above more than 70%, every case fertilized egg hatchability of fertile eggs when 700 ~ 800 g all can reach more than 85% through 5 years test incubation rates.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is respectively arranged with the structural representation of permeable hole and apopore for incubator box base plate among the present invention and back side panel;
Fig. 3 is for being set with the structural representation of bolting silk net in the incubator box among the present invention.
In the accompanying drawings: 1 water inlet pipe, 2 incubator boxs, 3 apopores, 4 incubation tanks, 5 outlet pipes, 6 incubator box baffle plates, 7 permeable holes, 8 back side panels, 9 bolting silk nets.
Embodiment
Be a specific embodiment of the present invention as depicted in figs. 1 and 2, the present invention includes incubation tank 4, be arranged on the incubator box 2 that is arrangement arranged side by side in the incubation tank 4 and and incubation tank 4 water inlet pipe 1 and the outlet pipe 5 that are connected, described water inlet pipe 1 and outlet pipe 5 are separately positioned on the head end and the end of incubation tank 4.As shown in Figure 2, the base plate of described incubator box 2 is provided with permeable hole 7, described incubator box 2 along water (flow) direction back side panel 8 be provided with apopore 3, described incubator box 2 is provided with the incubator box baffle plate 6 of fixedlying connected with incubator box 2 along the back side panel 8 of water (flow) direction.As shown in Figure 1, four incubator boxs 2 are arranged in the incubation tank 4 side by side, distance between each incubator box is 10 ~ 15 cm, with rope incubator box 2 is fixed in the incubation tank 4, make incubator box baffle plate 6 bottoms of fixedlying connected and the inwall and the bottom surface close proximity of incubation tank 4 with incubation tank 4, the water that flows into incubation tank 4 from water inlet pipe 1 is by 6 interceptions of incubator box baffle plate, thereby the permeable hole by diameter 3 ~ 5 mm on incubator box 2 base plates 7 upwards recoil enters incubator box 2, when water level exceeds incubator box baffle plate 6, the water just apopore 3 of the diameter 3-5 mm from the incubator box side plate flows out, enter next incubator box more in an identical manner, outlet pipe 5 from incubation tank 4 ends flows out at last, reaches the effect of flowing water hatching.40 ~ 80 purpose bolting silk nets 9 of suit can prevent the loss of fertilized egg in the incubator box 2.The present invention is simple in structure, and production cost is low, and it is little to take the production space, energy savings, and manageability, easy and simple to handle, can carry out the high density hatching.Put into fertilized egg 500 ~ 1000 g in each incubator box, incubation rate is more than 70%, and when fertilized egg was 700 ~ 800 g in each incubator box, hatchability of fertile eggs can reach more than 85%.
