Baking soda, also known as sodium bicarbonate (NaHCO), is a widely used weak base salt. It not only plays an important role in the kitchen, but also shows its unique charm in aquaculture.
Today, we'll explore the wonders of baking soda in aquaculture and see how it can be the secret weapon for a healthy farming environment.
1. The magic of baking soda in aquaculture
Regulating water quality: For aquatic organisms, a suitable pH is necessary for life and reproduction. As a weakly alkaline substance, baking soda can effectively regulate pH in water. When the water is acidic, baking soda can neutralize the acidic substances and slow the decline of pH value, thus maintaining the acid-base balance of the water.
Promote digestion: Adding the right amount of baking soda can put farmed animals in a slightly hungry state, contribute to their intestinal health, promote digestion, and improve the utilization of feed.
Pest control: Baking soda has a killing effect on some diseases and pests at a certain concentration. It can be used as an auxiliary component of antacids, insect repellents and antifungal agents to prevent water mildew, malformation of fertilized eggs of prawn or malformation of seaweed larvae. In addition, baking soda can also combine with heavy metal ions in water bodies to form insoluble carbonates, reducing the toxic effects of these substances on aquatic animals.
Relieve stress: When aquatic animals are stressed by environmental changes and transportation, baking soda can relieve their stress response and improve their survival rate.
2. Usage and dosage of baking soda
Although baking soda has many wonderful uses in aquaculture, it also needs to be carefully controlled when using it. The following are some common usage and precautions:
Adjust the pH value: During heavy rains or when the pH fluctuations caused by excessive algae in the cultured water body are large, baking soda can be used to buffer. The general dosage is 4 ~ 5 kg /(mu · m), and the water is evenly sprinkled throughout the pond.
Promote digestion: When the fish do not eat for unknown reasons or poor feeding, add 0.3-0.5% baking soda in the feed, mix evenly and feed.
Disease prevention: When treating bacterial diseases, it is recommended to use baking soda and liver medicine for the first meal of the day to detoxify and nourish the liver. The internal dosage of baking soda is 250 grams per 50 kg of feed for 3 to 5 days.
Relieve stress: Before transportation or environmental changes, use 0.5-1 kg of baking soda per mu of water (water depth of 1 meter), and sprinkle the whole pool after dissolution.
Third, precautions
1. In the case of high ammonia nitrogen in the fish pond, it is best not to use baking soda, because use at this time may be ineffective or even exacerbate the problem.
2. Baking soda is highly toxic to some fish (such as ð« fish) and should be used when necessary
3. Excessive use may cause the pH value of the water body to be too high, and the dosage should be strictly controlled when using.
4. Avoid mixing with acidic substances (such as vitamin C) to avoid chemical reactions and reduce the effect.
5. Pay attention to storage: Baking soda should be stored in a dry, cool place to avoid moisture clumping.
6. Observe the reaction: After using baking soda, you should closely observe the reaction of aquatic animals and water quality changes, and adjust the amount or stop using in time if there are abnormalities.
The reasonable use of baking soda can effectively improve the aquaculture environment and improve the health level and production of aquatic animals. However, farmers should follow scientific methods and precautions when using to ensure the best results and safety.
