Results of Implementing the Online Reporting System for Oxygen Enrichment in Aquaculture Using Solar-Powered Energy for Cage Fish Farming

Abstract

Fish farming in ponds is popular due to its effective environmental control, whereas cage farming in rivers and canals faces challenges due to unregulated flowing water. Despite this, many farmers prefer cage farming due to lower costs and the absence of pond space expenses. A major issue in cage farming is low oxygen levels at night, which can lead to oxygen deprivation, reduced growth, or even mortality. However, oxygen parameters are not the only factors influencing fish health and growth. Other elements, such as fish density, feed quality, disease management, and water temperature, also significantly impact fish performance. To address the issue of oxygen deficiency, an advanced oxygen enrichment system was developed, utilizing solar-powered electricity to maintain optimal oxygen levels. The system automatically activates when oxygen levels drop, releasing pressurized air to maintain stability. It is equipped with sensors for real-time monitoring and uses stored solar energy to operate continuously, reducing operational costs and ensuring sustainability. The system's main features include solar panels for energy generation, battery storage for nighttime operation, and automated oxygen release when levels fall below a set threshold. After one year of operation, the system maintained an average oxygen level of 8.2 ppm and proved reliable, average power output of 300 W. These results showed that the system provides a stable environment for fish growth, thereby improving efficiency and reducing the risk of oxygen deprivation. This approach offers a cost-effective, sustainable solution for river cage farming, enhancing fish health and overall productivity. Nonetheless, optimizing other factors like fish stocking density, nutritional input, and disease management practices are also essential for achieving the best outcomes in cage aquaculture.
