UV (Ultraviolet) rays is a form of electromagnetic radiation that has a wavelength shorter than visible light but longer than X-rays. UV rays are invisible to the human eye since their wavelengths are outside the range of visible light, but may affect living objects and organisms.

UV lamp as a sterilization tool

However, besides the sun, UV rays can also be obtained from artificial sources like UV lamps. Artificial UV-C lamps are frequently used in the context of human activities as a sterilization and disinfection tool because they are thought to be effective at eliminating harmful microorganisms like bacteria or viruses.

In shrimp farming, UV lamps can be placed depending on their intended usage, for example water sterilization. The use of UV lamps in UV filters is considered to be able to lower the level of microbial contamination and help prevent the spread of disease and increase the survival rate of shrimp. In addition, algae growth can also be controlled because UV light can kill or inhibit the reproduction of algae in water.

The use of UV filters in the sterilization of shrimp farming water can also help to enhance water quality by reducing pathogen contamination. Cleaner and sterile water can create more optimal conditions for shrimp growth and health.

Advantages and disadvantages of using UV lamps

The UV lamp in the UV filter for sterilizing water in shrimp farming has several advantages, including:

  1. UV lamps are known to be more effective against viruses or bacteria than chlorine.
  2. UV lamps are more environmentally friendly than chlorine and prevent overdose that could affect shrimp.
  3. Unlike chlorination, UV lamp sterilization does not cause molecular or color changes to the water.
  4. It is more economical and affordable because it does not consume a lot of power.
  5. The maintenance is simple and easy because one UV lamp can work effectively for around 1 year.

Although it has many advantages, using a UV lamp for water sterilization also has disadvantages, including:

  1. The effectiveness of UV lamp performance will be disrupted if the water used is not cleared first.
  2. Due to their high reliance on electricity, UV lamps will not be able to work when a short circuit or power outage happens. 

One crucial point, the use of UV rays must be done carefully. Avoid direct contact with UV rays; better yet, use protective equipment. UV irradiation in pond water should be done regularly and not accompanied by the provision of certain feeds or medications.

Actually, currently there is no general benchmark for calculating UV lamp usage in shrimp farming. The calculation may vary depending on the purpose and specific cultivation conditions. Therefore, more specific and detailed calculations regarding UV usage in shrimp farming may include product testing and adjustments based on respective cultivation conditions. Testing can be conducted by checking the water before and after passing through UV light sterilization. It is advisable to consult with an expert or professional who has experience in shrimp farming to ensure that the calculation is more accurate.
