First, high-quality seedlings
Many times prawns are not well raised in the market, and many farmers will blame this kind of fry for the first time, which shows the importance of fry to successful breeding, so you can choose high-quality fry for breeding.
Second, strengthen seedlings and protect seedlings
Select high-quality seedlings, reasonable stocking density, protect the seedlings, keep them alive, control the water body in the middle and late stage, and produce them.
Third, nutrition.
In the process of aquaculture, people pay more attention to the nutrients needed for shrimp growth, but often ignore the supplement of nutrients needed for algae and microorganisms in water and the decomposition and utilization of excess nutrients at the bottom of the pond.
Fourth, dissolved oxygen.
Dissolved oxygen is the key to the success of aquaculture, but in fact, we pay more attention to dissolved oxygen in water and ignore the ability of shrimp to carry dissolved oxygen, which is also a direct manifestation of water quality and sediment.
Five, disinfection
Disinfection is the control of harmful bacteria concentration, and it can't kill all harmful bacteria. Under favorable conditions, harmful bacteria will multiply rapidly, so it is very important to grasp the disinfection opportunity and pursue effective disinfection. Correct operation after disinfection is very important!
Sixth, control
In aquaculture and water production, we often talk about the balance between algae and bacteria.
