By the following examples the monomer unit that a kind of river eel incubating oosperm of the present utility model and newly hatched larvae are cultivated is set forth.
1, apparatus structure
User obtains monomer unit as shown in Figure 1, and as shown in Figure 1, cell body 11 is of a size of long 600mm, wide 150mm, high 465mm, wall thickness 8mm.As shown in Figure 1-2, the diameter of ring part 12 is 400mm, thickness 150mm, wall thickness 8mm; Its upper end open length is opening 250mm, and the two ends of opening respectively extend the plank of a high 45mm, thick 8mm identical material, and a little tank is welded as bracket 13 in side, plays the effect of fixed water inlet pipe.Ring part 12 is welded on the bottom of cell body 11, and have the mudhole 51 that an aperture is 50 centimetres, mudhole 51 is connected with blowdown ladder pipe 52, and described blowdown ladder pipe 52 turns the straight tube of 20mm for caliber 50mm, and on the pipeline of caliber 20mm, be provided with blowdown by-pass valve control 53.
As Figure 1-3, described water intake mechanism 2 is arranged on described bracket 13, adopt four hole current dividers 22, each tap hole respectively connects a caliber 8mm, the water inlet pipe 21 of length 12mm, water inlet pipe 21 is fixed on bottom described bracket 13 by threading threaded elbow, and elbow the most carefully locates external diameter 6.4mm, intermediate thread is G1/4 screw thread, and it is 6.4mm that pigtail connection the most carefully locates external diameter.
As shown in Figure 1-2, described drainage mechanism 3 comprises a pipe range 15cm, pipe external diameter is 60mm, the draining separator tube 31 of internal diameter 50mm, the anti-sealing of termination DN50 pipe cap of draining separator tube 31 overflows, and position is connect one and to be connected by bore 20mm elbow and the bore being turned horizontal direction by vertical direction is the drainpipe 32 of 20mm therebetween.
As shown in Figure 1-2, in described water injecting mechanism 4, water injection pipe 41 is positioned at 10cm place on circular portion bottom, and two water injection pipes are symmetrical, and the bore of water injection pipe 41 is 20mm, the caliber of the elbow be attached thereto is 20mm, and the described duck-beak type shower nozzle 43 be connected with elbow rotates to being 45 ° obliquely.
Also fluorescent lamp is provided with above described body 1.The outside of described fluorescent lamp is covered with black lampshade.The illumination of described fluorescent lamp is 500-1000lx.As shown in Figure 4, described cultivator is also provided with the bait throwing in that to match with mudhole 51 and blocks pipe 6, one end mouth of pipe blocking of described bait throwing in blocking pipe 6, and the pipe diameter of described bait throwing in blocking pipe 6 is 50mm, and the length of described bait throwing in blocking pipe 6 is 600mm.
2, step is used
First open water inlet control valve door 23, make water inlet control valve door 23 be in the state opened, control valve always, produce stable circulation rotating current, bottom making cell body 11, average current velocity controls at about 5.5cm/s.Fast rotational current can keep willow leaf zoea larva eel seedling to be suspended in water, both eel seedling downstream had been avoided to cause lower jaw abnormality to body 1 bottom, avoid again that impulse force is excessive to be damaged eel seedling, and the food of seedling and their remaining ight soil can be prevented to be attached on the wall of body 1.Meanwhile, the draining control valve door 33 in drainage mechanism 3 is also in the state opened, and by regulating draining control valve door 33, make to reach balance into water draining, the moment more renews water, for eel seedling provides a good water environment.
When bait throwing in, bait throwing in is blocked pipe 6 and inject described mudhole 51 bottom cell body 11, mudhole 51 is blocked.Then open the fluorescent lamp above body 1, first close water inlet control valve door 23 and draining control valve door 33.With glass pipette, the bait of 5mL is delivered to the bottom of cell body 11, due to the negative phototaxis of common eel, eel seedling can move to this place food.Feeding, after 15 minutes, closes fluorescent lamp, now removes bait throwing in blocking pipe 6.Open Fill control valves door 43 after static 10 minutes, control water velocity, by duck-beak type shower nozzle 42, bait residue is passed through mudhole 51 with water, pour blowdown ladder pipe 52.Open blowdown by-pass valve control 53 bait residue is drained.Close blowdown by-pass valve control 53 and Fill control valves door 43 again, reopen water inlet control valve door 23, the impact that the eel seedling of bottom is subject to current can suspend in water.Meanwhile, open draining control valve door 33, keep the water circulation in body 1.
In sum, the monomer unit that the utility model provides a kind of river eel incubating oosperm and newly hatched larvae to cultivate, in conjunction with the setting principle of other biological incubator, develop the device being suitable for common eel fertilized egg and newly hatched larvae cultivation of a set of uniqueness, this apparatus structure is simple, design ingenious, easy to use, highly apply.So the utility model effectively overcomes various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all without prejudice under spirit of the present utility model and category, can modify above-described embodiment or changes.Therefore, such as have in art and usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that the utility model discloses, must be contained by claim of the present utility model.
