First, there are two kinds of shrimp eggs that can hatch, one is fine eggs, and the other is red eggs. When I first bought them, the fine eggs claimed that the hatching rate was 85%. Personally, it was 70% at most. Although it is cheaper. However, the hatching rate is low, many eggs are sunk, and it is not easy to separate, so in general, it is cheated.

Figure 1 red egg, Figure 2 shows fine egg. You can see that the color of the big red egg is redder than that of the fine egg. The particles are slightly larger, and the picture is not easy to see.

Second, crude salt. Needless to say, there are aquarium supplies everywhere, and I bought 1 yuan a catty. I can use it for half a year for 5 yuan.

Third, an air pump, 2W or 3W will do.

The fourth sample, measuring spoon, is shown below, and the blue color is 12g spoon. White is 1g spoon. Actually, no. It's just a rough measure.

Fifth, incubation equipment. Because of the poor economic conditions at home, I couldn't afford the finished equipment, so I made it myself. Let's take a look at how to do it. I'm just teaching novices. Don't say that what I have read is tantamount to writing in vain. If you don't want to see it, go elsewhere and study something profound.

Here are the parts of the incubation equipment, four things, trachea, air valve, coke bottle, and the bottom of the coke bottle needs to be cut off, because I forgot to shoot the bottle. Everyone has seen it, right? The 2L type.

When everything is ready, punch a hole in the coke bottle cap and insert the air regulating valve. You can use a small electric drill, an awl, etc., as long as the hole you open can just be inserted tightly into the air valve. Pay attention to the size of the hole. It is too big to be inserted tightly, but too small to be inserted. It's best to expand the interface of the air valve before inserting it. This is called a cap with a big rod and a thin rod, so it won't leak inside.

Insert the air valve inserted into the bottle cap into the trachea.

The other end of the trachea is inserted into the air pump. Turn off the air valve at this time. Then fill the bottle with water, don't fill it too full, or the water will easily shoot out when it is pumped up later. Go on, add 1 to the bottle with a blue spoon. 5 tablespoons of salt, and then add 3-5 tablespoons of eggs with a white spoon after the salt is completely melted, all of which are flat spoons. Don't let your spoon tip. The hatching rate will be lower if there are more eggs.

Then turn on the switch of the air pump first, and then turn on the switch of the air regulating valve. The incubation has begun. I didn't hang up the bottle because sometimes water comes out, so I made a small jar to catch the water, which was a little wide. I should make it narrower and higher next time. Just let the bottle stand up.

It is necessary for shrimp eggs to roll up in the bottle.

If the temperature is 28 degrees, it will take 20 hours. Now, if the room temperature is 23 degrees in the north, it will take more than 30 hours to hatch.

It's 23 degrees in my house. After 30 hours, the bumper shrimp hatched. I used small eggs this time. You can see that the shrimp hatched from the small eggs mixed with the sunken eggs and sank to the bottom. The separation condition is not ideal.

But I have good goods. Harvest shrimp separation net.

Two nets, one with 80 meshes, the other with 200 meshes, with 80 meshes placed on top of 200 meshes, and the two nets are stacked together. Then close the air regulating valve, pull out the air pipe at the end of the air pump, aim the air pipe at the separation net, and open the air valve to drain water. At this time, a mixture of shrimp and sunken eggs flowed out.

Put the stacked net away, take the shrimp to the toilet and start flushing with the shower head. The eggs are brown, and the shrimps are orange. When you see that there is no orange substance in the upper net, most of the shrimp have passed through the 80-mesh net and landed on the 200-mesh net. Separation succeeded.
