Key points of pond cleaning operation in aquaculture

Owners in the aquaculture industry are aware that ponds can experience various problems after several years of continuous use, leading to diseases and even deaths of aquatic animals, resulting in significant losses. Therefore, we need to regularly clean the ponds, especially the old ponds that have been farmed for many years.

Pond cleaning has a positive significance in reducing animal diseases, increasing production, and increasing profits. As the name suggests, pond cleaning can be divided into two types: cleaning and cleaning. Usually, we need to decide which one to adopt based on the specific situation of sugar consumption. The main focus of the whole pond is to repair the pond ridge and improve water and aquaculture facilities, while the cleaning of the pond is aimed at the mouth of the pond where the deterioration of water and sediment is more severe. It is necessary to remove excessive sediment at the bottom, kill harmful viruses, bacteria, algae, and various pathogens in the pond, and ensure the healthy growth of aquatic animals. The specific measures to be taken for pond cleaning are summarized by aquatic animal protection manufacturers as follows:

Steps for pond cleaning

1. Removal of some bottom sludge: The bottom sludge with proper thickness is fertile soil for the growth of various beneficial bacteria and algae, and can also provide a healthy ecological space for breeding animals. However, too much sediment becomes a hotbed for the breeding of viruses and harmful bacteria and algae. Usually, the thickness of the bottom sludge is 5-10cm, otherwise it is easy to have negative effects such as oxygen deficiency at the bottom, high ammonia nitrogen and sulfite content in the water body.

2. After dredging, fully sunbathe the pond: Because there is a lot of sludge at the bottom of the pond mouth that has been used for a long time, and the sediment contains a large amount of harmful bacteria and viruses, these bacteria can be killed through sunbathe, usually for about a month, to improve the physical and chemical properties of the bottom soil.

3. Thoroughly clean and disinfect the pond: Some stubborn bacteria cannot be completely killed by sun drying the pond, so disinfection products need to be used for disinfection and sterilization. Generally, quicklime can be used to sprinkle, and after disinfection, water can be tested for about half a month to release the seedlings.

4. Using bottom modified water conservation products: After clearing ponds and releasing seedlings, it is necessary to maintain a stable and healthy state of the water body, and to regularly use aquatic products for bottom modified water conservation.

5. Application of bottom modification products: For ponds where the bottom deterioration is not very severe and the sediment is not particularly thick, chemical bottom modification can be used to improve the bottom quality, reduce the ammonia nitrogen content in the sediment and water body, and make aquatic animals healthier!
