What are the key points of shrimp hatching in bumper years? How long is the life span of dormant eggs?

Harvest shrimp, also known as harvest insect fairy shrimp, exists in salt lakes and salt fields on the mainland and has high nutritional value. The swimming posture of harvest shrimp in the water is very beautiful, and they are also excellent bait for fish. Next, let's take a look at what are the key points of harvest shrimp hatching techniques? How long is the life span of dormant eggs?

First, what are the key points of shrimp hatching in bumper years?

1. Pour the open container into clear water at a height of about 5CM, put in half a spoonful of salt and melt it evenly. After the water surface is calm, spread the shrimp eggs evenly on the surface. At this time, try not to shake the container, lest the harvest shrimp eggs stick to the container wall due to the vibration of water.

In about 10 hours, the shrimp seedlings have come out in the bumper year, and a large number of shrimp seedlings have come out in 16 hours. At this point, pour the hatching container with shrimp into the processed large beverage bottle.

3. After standing still in the large beverage bottle for 30 minutes, you can see that most of the shrimp fry have gathered at the bottom of the container, showing orange cloud shape, and then you can suck the shrimp fry into the small plastic bottle with a straw. Note that the straw should not be inserted into the bottom of the container to prevent sundries from being sucked out, so that it is best to be in the "orange cloud" (the center of shrimp fry activity), so that the harvest shrimp separated is also the cleanest.

4. Slowly pour the water from the small beverage bottle onto a small net with very fine density, and then rinse it with a small stream of tap water to get a cleaner and fresh opening material that small fish can eat-harvest shrimp.

5, the general family breeds small fish, the quantity, the frequency is too many, the small fish can not finish the harvest shrimp at a time can be frozen immediately. At that time, it will be like feeding a frozen hamburger, the small fish will be open to all, and the nutrition is still rich.

6. If you want to breed more harvest shrimp at one time, or make the emergence of harvest shrimp more sustainable, you can have more than several utensils, just do the same.

Second, how long is the life span of resting eggs in bumper years?

The dormant egg can survive for about 5 years when it is preserved under the condition of low temperature and dry temperature. when it re-enters the normal temperature seawater or absorbs water in a humid environment, the embryo in the shell begins to metabolize and enter the hatching process. and finally break out of the shell and become nauplius.

Newly hatched nauplius shrimp with yolk sac, do not need to eat within a day, rely on the consumption of nutrients to grow, from the nutritional value point of view, after a day will be reduced by about 20%. If the larvae of small or large fish are to be fed with nauplius, they should be collected and fed as soon as possible during the hatching process. Nauplius under suitable conditions, after about ten days of rearing, can reach the length of adult harvest shrimp, about more than 1 cm for females and 0.7 cm for males.
