Introduction
Fish farming is a profitable venture, but diseases can lead to significant losses if not managed properly. Understanding common fish diseases, their symptoms, and effective prevention methods is crucial for successful aquaculture.
1. Common Fish Diseases and Their Causes
✅ Bacterial Diseases
- Columnaris (Cotton Wool Disease): White cotton-like growth on fins and gills, leading to ulcers.
- Aeromonas Infection (Ulcer Disease): Red spots, open wounds, and sluggish movement.
- Dropsy: Swollen body, protruding scales, often due to kidney failure.
✅ Viral Diseases
- Koi Herpes Virus (KHV): High mortality, gill necrosis, and erratic swimming.
- Spring Viremia of Carp (SVC): Hemorrhaging, swollen belly, and difficulty breathing.
✅ Parasitic Diseases
- Ichthyophthirius (Ich or White Spot Disease): White cysts on the body, itching behavior.
- Gill Flukes: Heavy mucus secretion, breathing difficulties.
- Costia (Skin Slime Disease): Excess mucus, red patches on the body.
✅ Fungal Diseases
- Saprolegniasis (Water Mold Infection): Cotton-like patches on the skin, lethargy.
✅ Nutritional and Environmental Disorders
- Ammonia Poisoning: Red gills, gasping at the water surface.
- Oxygen Deficiency: Lethargy, crowding near aeration points.
2. Disease Prevention Strategies
✅ Maintain Water Quality
- Regularly check pH (6.5-8.5), ammonia, and oxygen levels.
- Use biofilters and aeration systems for proper oxygenation.
✅ Proper Stocking Density
- Avoid overcrowding, as it increases stress and disease risks.
- Follow recommended stocking ratios for specific fish species.
✅ Quarantine New Fish
- Always quarantine new fish for at least 2 weeks before introducing them into the main pond.
- Use salt baths to eliminate external parasites.
✅ Balanced Nutrition
- Provide high-quality, nutrient-rich feed to strengthen fish immunity.
- Avoid overfeeding to reduce water pollution.
✅ Regular Health Monitoring
- Observe fish behavior daily for signs of stress or disease.
- Remove sick fish immediately to prevent disease spread.
✅ Use of Natural and Medicinal Treatments
- Salt Bath (for Parasites): 2-3% salt dip for 5-10 minutes.
- Potassium Permanganate (for Bacteria & Fungi): Diluted bath treatment.
- Aloe Vera Extracts: Natural immune boosters for fish.
✅ Vaccination and Biosecurity Measures
- Vaccinate fish against common viral and bacterial infections.
- Prevent water contamination by properly disposing of dead fish.
