2.3.2. Measurable and Controllable System
- Environmental and growth indicators must be monitored regularly
- Data-driven adjustments for continuous optimization
3. Practical Experience to Increase Fish Farming Productivity by 20–30%
3.1. Optimize the Fish Farming Process from the Preparation Stage
An effective Fish Farming Process always starts with proper technical preparation rather than dealing with issues later.
3.1.1. Standardize the Farming Environment Before Stocking
- Maintain stable pH levels between 6.5–8.5 before stocking
- Clean pond bottoms to minimize toxic gas accumulation
- Actively manage water inflow and outflow to control water quality
3.1.2. Select the Right Time for Stocking Fish
- Stock fish in the early morning or late afternoon to avoid thermal shock
- Avoid stocking during unstable weather conditions
- Acclimate fish to the water environment before release to improve survival rates
3.2. Manage Feeding and Growth Efficiency
In the Freshwater Fish Farming Process, feed accounts for a significant portion of costs, so optimizing this stage directly improves productivity.
3.2.1. Adjust Feeding Regimes by Growth Stage
- Early stage: prioritize high-protein, easily digestible feed
- Growth stage: balance nutrition to optimize Feed Conversion Ratio (FCR)
- Pre-harvest stage: minimize losses while maintaining fish weight
3.2.2. Control Feed Quantity and Reduce Waste
- Feed based on actual demand rather than estimation
- Monitor feeding behavior to adjust promptly
3.3. Maintain Stable Water Conditions and Farming Systems
A key factor for achieving high productivity in the Fish Farming Process is maintaining a stable living environment.
3.3.1. Monitor Environmental Parameters Regularly
- Keep dissolved oxygen (DO) at safe levels
- Check NH3 and H2S to prevent toxicity
- Adjust water temperature and clarity as needed
3.3.2. Invest in Durable Farming Systems
- Use high-quality nets to ensure durability and proper water flow
- Strong ropes help stabilize cages under current conditions
- HDPE floats maintain system structure and reduce replacement costs
3.4. Proactively Prevent Disease Instead of Reactive Treatment
In practice, successful models applying the Fish Farming Process prioritize prevention over treatment.
3.4.1. Build a Biosecurity-Based Fish Farming Process
- Prevent contaminated water from entering the farming system
- Control the quality of fingerlings and feed inputs
- Perform regular sanitation of the farming area
3.4.2. Detect and Handle Abnormal Signs Early
