Described hatchery 120 upper lifting has bulb 140.When taming and dociling food after fry membrane, utilize the phototaxis of fry, by bulb 140, fry is focused among a small circle, good concentrated bait of throwing something and feeding, be beneficial to improve and tame and docile food effect.
Be configured with the temperature control system measuring water temperature in hatchery 120 in this greenhouse, the display panel 150 of described temperature control system is suspended in the top of hatchery 120.Temperature control system can control the temperature in hatchery, controls the hatching of fertilized egg.Display panel 150 is beneficial to keeper and watches temperature, adjusts accordingly in time to hatching house's temperature.
The equipment carrying out micro-pore oxygenation in described hatchery 120 is configured with in this greenhouse.Micro-pore oxygenation equipment is beneficial to the hatching of fertilized egg; Because fish fertilized egg is generally produce on fish nest, micro-pore oxygenation equipment can increase with fertilized egg fish nest lay density, be beneficial to and improve hatchery availability.
Described greenhouse is originally external is coated with sunshade net 133.At sunny hot weather, for preventing hatching house's temperature too high, sunshade net can be pulled on and lower the temperature; When hatching house needs to heat up, sunshade net can be drawn, very easy to use.
Described greenhouse body 130 is provided with the window 134 that user is ventilated.At the noon of sunny hot weather, if temperature is too high in greenhouse body 130, can also, by opening front and back window 134, carry out aeration-cooling.
Spawning water filtration system, as shown in Figure 5,6:
This Spawning water filtration system comprises filter element 160, and the filter screen side of described filter element 160 is provided with water body agitating device.Generally, water body is when passing through the filter screen in filter element 160, the foreign material that on wire side, easily attachment is a large amount of, easily cause the blocking of mesh, and by arranging water body agitating device at filter screen side, so this agitating device just has certain agitaion to the water body of filter screen side, foreign material in water body also can be in agitated conditions all the time under the effect of agitating device, so water body is when by filter screen, the blocking of mesh is caused on foreign material would not be attached to filter screen surface with water body flow, even if foreign material are attached to after on wire side, by the effect of agitating device, foreign material also can be washed down, the problem that mesh blocks can not be caused.
Described agitating device is paddle aerator 170.Water can also be carried out aeration by paddle aerator 170 while providing enough oxygen to fish reproduction water body, and poisonous and harmful substance in water body is volatilized away, reduces concentration of narmful substance, increases water quality.The turning effort of its impeller of aerator 170 can also make water body be in agitated conditions, and in anti-water-stop body, foreign material are attached to the wire side of filter screen, avoid the blocking of sieve meshes.Paddle aerator 170 avoids traditional artificial swiped through journey, reduces the human cost of cultivation.
Described filter element 160 comprises the single filter net 161, cascade filtration net 162, three-stage filtration net 163, the level Four screen pack 164 that reduce gradually along the aperture of filter screen that water body circulating direction tackles setting successively.Here single filter net 161 is mainly used for tackling larger fish, shrimp, foreign material, prevents from destroying water pumper, and its mesh should be maximum; Cascade filtration net 162 is mainly used in tackling zooplankton; Three-stage filtration net 163 is mainly used in tackling impurity tiny in water body, such as little trash fish and fish-egg; Level Four screen pack 164 filters minute impurities in water body further, and its mesh is minimum, finally guarantees to filter the breeding requirement that the water body obtained meets perch.
