DIYM O₂Rs Microbubble Aeration as an Alternative to Conventional Root Blower Systems in Super-Intensive Vannamei Shrimp Farming

The advancement of aeration systems is crucial in enhancing the productivity and sustainability of super-intensive whiteleg shrimp (Litopenaeus vannamei) farming. Therefore, this study aims to introduce and evaluate the performance of a novel aeration technology, namely Do-It-Yourself Microbubble (DIYM O2Rs), designed to optimize dissolved oxygen levels in shrimp ponds. The experiment was conducted using three treatments, including (1) DIYM O2Rs, (2) conventional Root Blower aerators, and (3) a combination of both systems. Post-larval shrimp with an initial average weight of 0.15 ± 0.07 g were stocked at a high density of 500 ind/m3. Parameters analyzed were dissolved oxygen (DO) concentration, growth rate, feed conversion ratio (FCR), survival rate, and water quality indicators. The results showed that DIYM O2Rs significantly improved shrimp growth rate and size to 0.20 ± 0.005 g/day and 64.18 ± 7.24 (ind/kg), respectively. These observations suggest that DIYM O2Rs is an alternative aeration solution, and the adoption can enhance water quality, shrimp health, and production efficiency, contributing to more sustainable super-intensive farming practices.
