Shrimp farmers in Indonesia are increasingly adopting ultraviolet (UV) treatment as a sustainable alternative to chemical options for reducing Vibrio presence in their ponds. Initially successful in shrimp hatcheries, UV technology is now being considered for use in grow-out ponds, offering benefits such as enhanced biosecurity, decreased shrimp diseases, reduced long-term water management expenses, and environmental friendliness.
Farmers, including Sidiq Bayu Kurniawan in Bali, have reported significant reductions in Vibrio presence and increased efficiencies in space and expenses with UV treatment. The technology eliminates the need for separate treatment ponds, providing a direct and more efficient treatment process. The integrated UV system with a sand filter enhances water clarity and maximizes effectiveness.
Recognizing the potential for substantial long-term savings, shrimp farmers in Indonesia are exploring UV technology as a viable option compared to traditional chemical disinfectants like chlorine or hydrogen peroxide. The Aquaculture Technology and Development (ATD) PT Suri Tani Pemuka, a subsidiary of Japfa Group, is actively exploring UV technology’s development and implementation in ponds to enhance biosecurity without leaving residues that could lead to pathogen resistance.
However, it’s essential to note that UV disinfection complements biological approaches, with chemicals still playing a role in water treatment sequences. UV treatment, particularly UVC with a wavelength between 250 and 265 nm, damages pathogens’ DNA structure, preventing replication and preserving water quality without producing residues.
Farmers are considering UV as a sustainable alternative, emphasizing the importance of maintaining specific water quality parameters for optimal UV effectiveness. While UV disinfection requires careful consideration of factors like UV intensity, retention time, and dosage, experts suggest that the initial investment in UV technology offers long-term cost-effectiveness, making it a preferred choice for environmentally conscious shrimp farmers in Indonesia.
