Preventing Low Dissolved Oxygen in Sustainable Organic Fish Farming Sustainable organic fish farming aims to minimize environmental impact while producing high-quality fish. A crucial aspect of this is maintaining adequate dissolved oxygen (DO) levels in the pond to prevent fishkill. This response will explore basic prevention techniques, sustainable organic fish farming methods, and technologies crucial for maintaining DO levels in both brackish and freshwater fish ponds. Understanding the Causes of Low DO Low DO is a significant threat to fish health and can lead to mass mortality. Several factors contribute to low DO levels in fish ponds, including: - Decomposition of Organic Matter: Fish waste, uneaten feed, and decaying plant matter consume oxygen during decomposition. - Respiration by Aquatic Plants: While plants produce oxygen during photosynthesis, they also consume oxygen during respiration, especially at night. - Warm Water Temperatures: Warm water holds less dissolved oxygen than cold water. - Overcrowding: High fish stocking densities increase oxygen demand, making it more challenging to maintain adequate levels. - Turbidity: Cloudy water reduces sunlight penetration, hindering photosynthesis and oxygen production by aquatic plants. To correct this, it is recommended to apply bi-monthly by 12-hours fermentation of 4 kg Organic Full Harvest Microbial Inoculant plus 1 gallon coconut juice per 200 liters potable water per hectare for brackish water (2 kg of Organic Full Harvest Microbial Inoculant for freshwater) Basic Prevention Techniques Several basic techniques can help prevent low DO in organic fish ponds: - Proper Stocking Density: Avoid overcrowding by maintaining appropriate stocking densities based on the fish species, pond size, and water quality. - Balanced Feeding: Feed fish only what they can consume within 10-15 minutes to minimize uneaten feed that decomposes and depletes oxygen. - Water Management: Regularly remove excess organic matter from the pond bottom to reduce oxygen demand during decomposition. - Water Exchange: Introduce fresh water to dilute organic waste and replenish oxygen levels, especially in smaller ponds. - Planting Oxygenating Plants: Introduce oxygenating plants like water hyacinth or water lilies or water spinach (Kangkong) to increase oxygen production through photosynthesis. Sustainable Organic Fish Farming Methods and Technologies Several sustainable organic fish farming methods and technologies can help prevent fishkill by maintaining adequate DO levels: - Biofloc Technology (BFT): BFT is a closed-system aquaculture method that utilizes beneficial bacteria (Organic Full Harvest Microbial Inoculant) to break down organic waste and produce microbial protein, which serves as a supplementary food source for fish. This technology minimizes water exchange, reduces waste, and enhances DO levels. - Integrated Multi-Trophic Aquaculture (IMTA): IMTA integrates different species, such as fish, seaweed, and shellfish, in a single system. This approach promotes nutrient cycling, reduces waste, and enhances oxygen production. - Recirculating Aquaculture Systems (RAS): RAS are closed-loop systems that recirculate and filter water, minimizing water exchange and waste discharge. They often incorporate aeration systems to maintain optimal DO levels. - Aeration Systems: Mechanical aeration systems, such as surface aerators or bottom diffusers, introduce oxygen into the water, ensuring sufficient DO levels, particularly during periods of high oxygen demand. - Shade Structures: Shade structures can reduce water temperature and minimize algal blooms, which can contribute to low DO. - Water Quality Monitoring: Regularly monitoring DO levels using dissolved oxygen meters is crucial for identifying potential problems and taking corrective actions. Conclusion Maintaining adequate DO levels is essential for the success of sustainable organic fish farming. By implementing a combination of basic prevention techniques and advanced technologies, fish farmers can create a healthy and productive environment for their fish. The adoption of sustainable organic fish farming methods and technologies (Victory Global Organic Farming Management System Technology) is crucial for ensuring the long-term viability of the aquaculture industry while minimizing environmental impact. Continuous research and innovation in this field are critical for developing more efficient and environmentally friendly solutions for fish production.
