✅ How to Prevent Fish Diseases – Expert Tips by Perfect Aqua Feeds

✅ 1. Feed High-Quality, Balanced Nutrition

Fish that receive low-grade or unbalanced feed have weak immune systems. Perfect Aqua Feeds offers protein-rich, species-specific diets fortified with:

• Beta-glucans – Natural immune boosters

• Vitamins & minerals – For tissue repair & disease resistance

• Spirulina & yeast extract – For gut health and detoxification

💡 Healthy fish = Strong immunity = No disease outbreaks.

✅ 2. Avoid Overfeeding & Water Pollution

Unconsumed food leads to ammonia buildup and harmful bacteria.Perfect Aqua Feeds' floating/sinking pellets are:

• Highly digestible

• Low water-pollution formula

• Engineered to reduce organic load in the pond

✅ 3. Maintain Good Water Quality

• Ensure dissolved oxygen > 5 ppm

• Keep pH between 6.5 – 8.5

• Regularly check ammonia and nitrite levels

🟢 Pro Tip: Our feeds perform best in stable water conditions—allowing fish to fully absorb the nutrients for health and immunity.

✅ 4. Regular Monitoring & Health Checks

• Weekly checkups for signs of stress, appetite loss, or skin damage.

• Keep detailed logs of feed quantity, growth rate, and behavior.

Always isolate new fingerlings for 10–15 days before introducing them into the main pond. This avoids cross-infection and gives fish time to recover from transport stress.
