1, preparation: natural seawater and fresh water can be mixed according to the ratio of1:1or1:2, or salt 10- 15g can be added to each liter of fresh water as hatching water. 2. Hatching method: Take the shallow tray hatching method as an example. First, the hatching water is injected into a long shallow tray, and then the eggs of the harvest shrimp are evenly sprinkled on the water surface, and usually the larvae of the harvest shrimp can be hatched after standing for 24-36 hours.

First, the harvest shrimp incubation tutorial

1, preparation work

(1) Because resting eggs can only be awakened by shrimp in water with a specific salinity, it is necessary to prepare suitable hatching water.

(2) Generally, the salinity required for hatching shrimp is only 1/3- 1/2 of natural seawater, so natural seawater and fresh water can be mixed according to the ratio of1:1or1:2.

(3) If seawater cannot be obtained, salt 10- 15g can be added to each liter of fresh water.

2. Hatching method

(1) Take the shallow tray hatching method as an example. First, prepare a long shallow tray and inject the hatch water that has been prepared already.

(2) Then, the eggs of the bumper shrimp are evenly sprinkled on the water surface, and after standing for 24-36 hours, the larvae can generally hatch, and the water temperature can generally be kept between 25-30℃, and the higher temperature is beneficial to the hatching of the bumper shrimp.

(3) When collecting, the larvae are gathered at one end of the plate by light, and then collected by dropper. It should be noted that this method is not suitable for hatching a large number of shrimp.

2. Where does the harvest shrimp generally grow?

1, Fengnian shrimp is widely distributed in salt fields or salt lakes on land. It is a typical super-saline organism with a slender body, generally 1.2- 1.5cm, which has high nutritional value. Because the larvae of Fengnian shrimp are small in size and easy to digest, it can be fed to small fish with imperfect digestive function.

2. For the newly hatched bumper shrimp, it needs to be washed several times before feeding. If it is bought from outside, you need to pay attention to the quality. Generally, it is recommended to hatch it yourself, which is more convenient and reassuring to use.

3. However, when feeding small fish, you can't just feed the harvest shrimp, because the salt in the harvest shrimp is too high and it has high fat. When the small fish eat too much, it will not only affect their growth, but also affect their body shape. Therefore, it is recommended to feed them together with a reasonable feed to make the small fish healthier.
