• Blind Feeding: In freshwater pond aquaculture, accumulated residual bait easily causes excessive ammonia nitrogen, while insufficient feeding results in uneven growth of fish schools. Estimating the feeding amount based solely on experience can lead to annual feed cost waste accounting for 15%-20% of the total aquaculture investment;
• Disease Prevention Difficulty: For groupers and salmon in marine cages, once they are infected with parasites or bacterial diseases, the initial symptoms remain hidden underwater. By the time abnormal fish conditions are detected, the disease has already spread—resulting in a minimum of 30% yield loss, and in severe cases, total mortality of the entire stock;
• Inefficient Management: Industrial recirculating aquaculture tanks are densely arranged, and manual inspections cannot cover all tanks in real time. Issues such as untimely removal of dead fish and abnormal water flow easily trigger chain pollution;
• Uncontrollable Risks: Deep-sea aquaculture areas are far from the shore. Factors such as typhoons and ocean currents may cause cage damage, which is difficult to detect in a timely manner through manual inspections. This leads to the escape of farmed organisms, with a single loss potentially reaching hundreds of thousands of yuan.
