How to Care for 60-Day-Old Catfish in Used Water Jugs to Keep Them Healthy and Plump
Raising catfish in used water jugs (galon bekas) has become a practical and efficient trend for home farming, especially for households with limited space. By the 60-day mark, a farmer’s main challenge is ensuring optimal growth so the fish reach an ideal weight. Here are 5 ways to care for catfish in used water jugs so they stay healthy, plump, and ready for harvest on time:
1. Optimize Water Quality Inside the Jug
At 60 days old, catfish have grown significantly larger, meaning they produce more waste and ammonia. Because the water volume inside a jug is quite limited (around 15–19 liters), water quality must be tightly managed.
- Routine Water Changes: Replace 30–50% of the water every 2–3 days. This step is essential to remove accumulated ammonia that could stunt growth.
- Healthy Water Color: Good water for catfish is typically brownish-green due to the presence of beneficial plankton. If the water smells foul or the fish start floating vertically at the surface, execute a total water change immediately.
2. Practice Proper Feed Management
To help catfish gain weight at the 60-day mark, feed selection and feeding techniques are decisive factors.
- Choose High-Protein Feed: Use fish pellets containing at least 30–32% protein. At this stage, catfish require substantial nutrition for muscle development and healthy fat buildup.
- Feeding Frequency: Feed them 2–3 times daily (morning, late afternoon, and night). Catfish are nocturnal, so nighttime feedings are often more effective for accelerating weight gain.
- Controlled “Ad Libitum” Technique: Feed until the fish appear full (when they stop striking at the food), but never leave leftover pellets at the bottom of the jug to prevent toxic buildup.
3. Add Supplements and Probiotics
Healthy, plump catfish usually rely on an efficient digestive system. You can mix liquid probiotics into the feed (bibis pelet) before offering it to the fish. Allow the pellets to absorb the probiotics for 5–10 minutes. Probiotics help catfish absorb maximum nutrients, resulting in firmer, denser meat.
4. Manage Stocking Density
Ideally, a single 19-liter used water jug should only hold 5–10 catfish through harvest. If the jug feels overly crowded at 60 days because the fish have grown, consider splitting them into an additional jug. Overcrowding causes stress, slows growth, and triggers cannibalism.
5. Physical Signs of Healthy, Plump 60-Day-Old Catfish
When cared for correctly, catfish at this stage will display the following traits:
- Aggressive Movement: Fish are active and respond quickly during feeding times.
- Proportional Body Shape: The belly looks round and filled out, rather than bloated from illness (dropsy).
- Glossy Skin: Normal mucus coverage on the skin without excess slime, open wounds, or white fungus.
- Uniform Size: Growth among the catfish within the same jug remains relatively even.
Conclusion
Cultivating catfish in used water jugs at 60 days requires diligence in water cleanliness and consistency with high-quality feed. With proper management, you can produce healthy, plump catfish ready for consumption—even when using repurposed containers right in your backyard.
