Specification: Condition: 100% Brand New Item Type: Shrimp Incubator Material: Plastic Color: As Pictures Shown Capacity: 380ml Weight: Approx. 279g Height: Approx. 28cm/11.02inch Using instructions: 1. Inject the treated water to the standard water level in the incubator tank, and add about 10g kosher salt to pre-dissolve 2. The air pump is connected to the air inlet hole at the bottom of the incubator, and the air volume is adjusted to an appropriate amount. The ideal temperature is 28 ~ 30℃ 3. Add about 3 to 5 g of shrimp eggs, can hatch smoothly after about 36 ~ 48 hours (depending on the incubation temperature and the quality of shrimp eggs in good harvest) 4. Collection operation: after the eggs hatch, stop pumping and let stand for about 10 ~ 15 minutes. When the shrimps sink to the bottom and the shells float, the larvae of shrimps can be collected from the original air inlet (air adjusting valve) at the bottom of the incubator, and then the larvae can be fed 5. If you have not eaten shrimp, please store them in the refrigerator. Applicable: dry, frozen shrimp eggs are applicable Incubation steps: 1. Add water 300 ml 2. Add half teaspoon of sea salt 3. Add 1 - 2 tablespoons of shrimp eggs 4. Connect air pump to open distributor 5. Waiting to hatch 6. Turn off the distributor and pull out the trachea Incubation temperature: Shrimp eggs can hatch in the range of 7-30 ℃, and the incubation speed is accelerated with the increase of temperature The preference incubation temperatureis 25-30 ℃. Salinity: Different kinds of shrimp eggs require different salinity when they hatch Place the eggs in fresh water (available mineral water) for 30-60 minutes before hatching to make the dehydrated eggs fully absorb water The eggs were then incubated in artificial seawater with a salinity of 3 percent It is suggested to use sea salt when modulating artificial seawater, because sea salt contains more kinds of ions, which is beneficial to the larva cracking. Package List: 1 x Check Valve1 x Suction Cup Fixed Holder1 x Shrimp Incubator Note: 1. Air supply port at the bottom of shrimp incubator, please adjust the air input. Too much or too little air input will affect the hatching time and survival rate of shrimp eggs. Please adjust the air input by air switch.2. The air supply port at the bottom is connected with a simple check valve, which can effectively prevent water backflow in the incubator.
