In the cold winter, especially in the South, many cities generally no central heating, so the temperature is lower than the northern cities. Brine shrimp eggs hatch should be kept above 20 degrees water temperature, 25-30 degrees among the best. To ensure high hatching rate and reduce the incubation time. Here are a few winter insects hatching method for your reference. Method one: a heated, will hatch bucket hanging near the radiator. But note that the water temperature should not exceed 32 degrees. (25-30 degrees among the best) method two, will be placed in the tank hatch barrel, use the tank temperature. Incubator to maintain vertical cheer barrel tank level is higher than 5cm above the water level, the barrels are able to remain vertical. If the tank is small, can not be placed in the incubator barrel. Can prepare a bit deeper bucket, Sheung Shui Sheng into heating rods, then placed in an incubator buckets, the same principle, and into the tank, half barrels are soaked in warm water can be. (But not on the hatch of the heating rods heated barrel, the local temperature is too high) Method three: a light bulb hanging above the incubator, use of light and heat. But not too close to the water bulb. Shrimp before taking the stage and take a small air pump tune shrimp stage, to turn off the lamp on the barrel, because shrimp phototaxis. Otherwise, it will affect the shrimp take effect. Winter incubation, hatching directly with warm water. The water is too cold, easy to shrimp eggs "shock" with. Second, when using the method, cheer tumbling after 30 hours, the incubator brought out hanging outside the cylinder, while the transfer of small air pump, 1-2 bubbles per second, about one hour later, shrimp and shell can separate sink, taking Shrimp fed either. (Note: The low temperature impact shrimp eggs hatch, did not affect the survival of shrimp.) Incubator should scrub clean with each use, do not rush to make a simple water trouble. Barrel inner wall will be deposited attachments, falling will breed bacteria, use a rag to scrub. Sediment hose; pour hot water bucket, hand water with a pinch of that will be discharged.
