In recent years, the benefits of shrimp farming have been getting worse and worse, and the high cost and low yield have reduced the profit margin of shrimp farming. Only by increasing the yield can the breeding benefit be improved, and one of the keys to increase the yield is to ensure the survival rate of shrimp seedlings. The survival rate of early breeding is high, and the output of later breeding can be guaranteed. To this end, this paper summarizes the five management points of early breeding for your reference.

1、 Prevention and control of bubble disease

Bubble disease is a common disease in aquaculture. It can produce bubbles in the body of shrimp seedlings, stimulate them or cause damage to them, resulting in the decline of their physique, delaying their growth, and in serious cases, inducing bacterial disease and aggravating their death. To effectively reduce the occurrence of bubble disease, suggestions: 1 Avoid putting seedlings in continuous sunny days, and try to put seedlings in early and late; 2. deepen the water level. The pond with thin water can be properly fertilized to reduce the light intensity of the bottom layer; 3. use bacteria preparation to stabilize water quality and reduce water change; 4. if bubble disease has occurred, it can be treated with "sujiean" + "activation" to reduce the damage of shrimp seedlings.

2、 Nutrition guarantee

When the biological bait in the water is sufficient, the growth needs of shrimp seedlings can be met, and the immunity and disease resistance are strong, which can effectively reduce the late disease and improve the survival rate. Zooplankton and hook shrimp in the water are high-quality early stage bait for car shrimp. Before and after releasing the seedlings, it is necessary to ensure that the amount of biological bait in the pond is sufficient. It is recommended to sprinkle "more bait" to cultivate insects to ensure nutrition supply. If the biological bait is insufficient in the early stage, Artemia can also be fed manually to ensure nutrition.
