In aquaculture and fish farming, various chemicals are used to promote fish health, treat water, and improve productivity. Here are some of the commonly used chemicals and their functions in detail:
- Disinfectants:
- Chlorine and chloramines: These are used to disinfect water, killing pathogenic microorganisms and keeping the water clean.
- Alcohols: Alcohols such as ethanol and isopropyl alcohol can be used for disinfecting surfaces and equipment. They are effective against bacteria, viruses, and fungi.
- pH stabilizers:
- Sodium hydroxide (NaOH), potassium hydroxide (KOH) or sodium carbonate: These chemicals are used to stabilize the pH of the water, maintaining an appropriate pH range for the fish.
- Antibiotics and antimicrobials:
- Oxytetracycline, florfenicol, sulfonamides, etc.: These are used to treat bacterial infections in fish, helping to fight diseases and improve fish health.
- Fungicides:
- Formalin: Formalin is used to control fungal infections that can affect fish.
- Growth promoters and vitamins:
- Various vitamins such as Vitamin C, Vitamin B-complex, etc.: These are used to promote fish growth and prevent deficiencies.
- Heavy metal binders:
- Zeolites and bentonite: These are used to bind heavy metals in the water, reducing their toxicity to the fish.
- Oxygenation agents:
- Hydrogen peroxide: Hydrogen peroxide is sometimes used to increase the oxygen levels in water and combat oxygen deficiency in ponds or tanks.
It’s important to note that the use of chemicals in aquaculture and fish farming is strictly regulated to minimize environmental impact and ensure food safety.
The specific chemicals and their use may vary depending on the type of aquaculture, local regulations, and the specific needs of the fish species.
Therefore, it is advisable to always adhere to the guidelines and regulations of the relevant authorities and promote sustainable practices.
