Disinfection methods of lobster culture ponds

Although at present, the vast majority of large-scale farms have a relatively complete biosafety system and health and epidemic prevention measures. However, specific to the disinfection pond, the situation of each farm is different, the common methods of lobster pond disinfection are quicklime disinfection box bleach disinfection two methods, let's take a look at it!

Quicklime disinfection

Before disinfecting with quicklime, only 5 cm of stagnant water is left in the pool water, and quicklime is broken and evenly sprinkled into the pool water to dissolve. The dosage of quicklime is generally 20-40 kg per mu. On the second day of using quicklime, stir the bottom of the pool with an iron rake to fully mix the lime slurry and silt. Because the calcium content of quicklime is more than 50% (theoretical value: 71.4%), the lobster will molt during the growth process, it must take in enough calcium, and quicklime is cheap.

Bleach disinfection

Using bleach to disinfect lobster ponds requires draining water, 0.5 kilograms of bleach with an effective rate of more than 30 percent per mu, 1.5 kilograms of bleach with a depth of more than 30 percent per mu of water in undrained ponds, and 1.5 kilograms to 2.5 kilograms of bleach per mu. When in use, bleach is first put into a wooden basin or iron bucket, diluted with water and sprinkled into the pond. Do not release the disinfected water, stay in the pool, start to enter the water the next day, and reach the required level of feeding.

Fire alkali disinfection

Now many lobster farms disinfect ponds generally use fire alkali disinfection, but fire alkali action is not rapid, ineffective to many viruses, corrosive, easy to react with carbon dioxide and fail. At the same time, fire alkali has a burning effect on the skin and organs, personnel engaged in disinfection operations should pay attention to self-protection, so as not to burn the skin.
