Abstract
The utility model relates to a hatch experiment device of sticky oosperm of fish, and the technical problem to be solved is to provide the hatch experiment device of the sticky oosperm of the fish, which is convenient for viewing the hatch process of fish fry. The hatch experiment device is composed of a hatch box, a water pump, an air charging device, a heating stick, foam blocks and a flat plate, and is characterized in that the upper part of the side edge of the hatch box is provided with a small hole used for installing a water inlet pipe; the lower part of the other side edge is provided with a small hole used for installing a water outlet pipe; two rectangular foam blocks are placed in the hatch box, and then one flat plate is clamped in the two foam blocks so that the flat plate is suspended in the hatch box; small glass sheets for placing the sticky oosperm are flatly paved on the flat plate; a dive type water pump, an air charging head and the heating stick are placed on the lower part of the hatch box. The hatch experiment device is used for hatch experiments of the sticky oosperm of the fish.
Description
Technical field:
The utility model relates to the hatching experiment device of the viscous fertilized ovum of fish.
Background technology
Present fry hatching device generally is to adopt hatching pail, incubation tank or circular hatching channal.In scientific experiment, conventional device is difficult for observing the process of fry hatching.
Circular hatching channal is built into by stone or brick and cement, and shape has circle or ellipse, and the number of circuit has monocycle, dicyclo and three rings.Circular hatching channal is made up of circuit, filtration screen window, intake-discharge pipe road and Ji Miaochi etc., the general wide 0.8～1.0m of circuit, about dark 1.0m, whole circuit bottom is 1% gradient to the hole direction of emerging, be convenient to drain the water and the fry of circuit, filter screen window and generally make with 46～55 hole purpose nylon bolting silks or copper wire cloth, screen window slightly tilts in circuit, is convenient to scrub.Circular hatching channal is large-scale fry hatching device.
Hatching pail is made with galvanized iron sheet or reinforced concrete, from the bottom water inlet, filters the screen window water outlet by top.Hatching pail is simple in structure, makes easily, and light and flexible, hatching density is big, the incubation rate height, therefore general use is wider.With the ovum cylinder of the water vat transformation of the way, similar to hatching pail, but that its water intake mode can have is multiple.
Incubation tank generally is the rectangle cement pit with brick one-tenth.The water inlet of incubation tank and water outlet are at same end, and two above duckbilled shower nozzle water inlets are established in the bottom, set out tank above the same end, are the rightabout water outlet with water inlet, and collection seedling pipe is located at the other end, and water forms circulation in groove, and fish-egg or fry are drifted about in the water.Bigger hatching flute length 2.5～3.0m, wide 1.5～2.0m, dark 1.2～1.3m, less length 1.7～2.0m, wide 0.7～0.8m is about dark 1.2m.Small-sized incubation tank can be lined up single file, duplicate rows or multirow to tens groove parallel connections by several.Incubation tank is simple in structure, and is easy to operate, manageable, and incubation rate is also higher, and every cubic metre of water of hatching density is put fish-egg 800,000～1,000,000.
The utility model content
The utility model technical issues that need to address provide a kind of hatching experiment device of being convenient to observe the viscous fertilized ovum of fish of fry hatching process.
The technical solution of the utility model is by incubator box, water pump, aerating device, heating rod, foam block, the dull and stereotyped composition, and the side top that it is characterized in that incubator box is opened an aperture and is installed into water pipe, opens aperture installation outlet pipe in another side bottom; Put into the square foam block of 2 block lengths in the incubator box, then 1 flat board is stuck in the middle of 2 foam blocks, flat board is suspended in the incubator box; The pieces of glass sheet of viscous fertilized ovum is put in tiling on the flat board; Submersible type water pump, pneumatic head, heating rod are put in the bottom of incubator box.
The utility model is with the advantage that other fry hatching device commonly used is compared: install small and exquisite simply, material is easy to get, and cost has functions such as temperature control, oxygenation, flowing water less.1 flat board is stuck in 2 foam blocks, flat board is suspended in the incubator box, and can regulate the dull and stereotyped suspension degree of depth.Along with the reduction of water level, flat board still is suspended in the water when changing water, can the influence when changing water drop to minimum.Because of flat board is suspended in the incubator box, the dirt that produces during hatching can leave flat board along with current, drops to naturally at the bottom of the case, reaches the purpose of purification, and dirt flows out thereupon when discharging water.Fertilized egg is directly sticked on the pieces of glass sheet, be convenient to adhere at any time the sheet glass taking-up of fertilized egg, be put into anatomical lens or microscopically observational study.The sheet glass that adheres to fertilized egg can be put back into after observational study finishes on the flat board of incubator box and continue hatching.
Description of drawings
What accompanying drawing was represented is structural representation of the present utility model.
Embodiment
The utility model (seeing accompanying drawing) is made up of incubator box 1, water pump 10, aerating device 9, heating handful 4, foam block 3, dull and stereotyped 7, incubator box 1 is that 5 blocks of glass stick into the casing that specification is 100cm * 60cm * 60cm, the white look paint in the outside of glass, open the water inlet pipe 6 of 3 centimetres of 1 diameters of aperture connection of 3 centimetres of 1 diameters on the side top of incubator box 1, open the outlet pipe 5 of 3 centimetres of 1 diameters of aperture connection of 3 centimetres of 1 diameters in incubator box 1 another side bottom, when quantity of exchanged water is big, can keep water state while intaking; Put into 40 centimetres of dark water 8 in the incubator box 1, put into the rectangle foam block 3 of 2 60cm * 20cm * 20cm then, with specification is that the flat board 7 of 60cm * 50cm is stuck in these 2 foam blocks, make dull and stereotyped 7 to be suspended in the incubator box 1, regulate the dull and stereotyped suspension degree of depth according to the test needs, flat board can be suspended in underwater 2 centimeters when for example hatching line thin white silk used in ancient China goby fertilized egg; At dull and stereotyped upper berth pieces of glass sheet 2, then fertilized egg (for example fertilized egg of line thin white silk used in ancient China goby) directly is put on the pieces of glass sheet 2 the beginning hatching process; 1 40 watts submersible type water pump 10 is put in the bottom of incubator box 1, and water pump 10 forms annular water flow, and the dirt that forms when hatching like this can leave flat board along with current, drops to naturally at the bottom of the case, reaches the purpose of purification; A plurality of pneumatic heads of aerating device 9 are put into so that keep sufficient dissolved oxygen in the bottom of incubator box 1, put 1 heating rod 4 and carry out temperature control in the bottom of incubator box 1.
Need observational study or when taking pictures, the sheet glass that adheres to fertilized egg is taken out, be put into anatomical lens or microscopically observational study.Study on the flat board that the sheet glass that adheres to fertilized egg can be put back into incubator box after finishing and continue hatching.
