Summary

This video provides a comprehensive guide on how to properly prepare and care for fish seedlings in bioflok ponds to ensure a healthy harvest. Key steps include ensuring the fish are healthy before stocking, using quarantine tanks to prevent disease, acclimating the fish to the pond's temperature, and adding salt to treat wounds or stress. The video also highlights the importance of maintaining clean water and using antibiotics during the early stages of growth. The process typically lasts between 5-14 days and ensures the fish grow healthy without succumbing to diseases or parasites.

Takeaways

• 😀 Ensure fish are healthy before releasing them into the bioflok pond to avoid mortality.
• 😀 If you have multiple ponds, designate one as a quarantine pond to ensure fish are disease-free before transferring them.
• 😀 For those with only one pond, temporarily use it as both the quarantine and bioflok pond.
• 😀 Keep the water level in the quarantine pond at a maximum of 60 cm to maintain water quality.
• 😀 Regularly replace at least 25% of the water in the quarantine pond to keep it clear and healthy for the fish.
• 😀 Add salt to the quarantine pond to help fish recover from stress or injuries, with a dosage of 1 kg per cubic meter of water.
• 😀 Gradually acclimatize fish to the pond environment by floating their containers in the pond to adjust to the temperature.
• 😀 Remove any fish showing signs of disease or injury (such as fungus or sores) to prevent contamination.
• 😀 Fast the fish for up to 24 hours after introduction to allow them to adjust to their new environment.
• 😀 Medicate the fish with antibiotics like Enroflox-25 during the first 3 days to prevent bacterial infections and promote health.

Q & A

Why is it important to quarantine fish fry before introducing them into a bioflok pond?

Quarantining fish fry helps ensure they are healthy before being exposed to the bioflok pond. This reduces the risk of disease or parasites being introduced into the main system, ensuring better survival rates and growth.

What should the water level be in the quarantine tank for fish fry?

The water level in the quarantine tank should not exceed 60 cm. This ensures proper water conditions and makes it easier to manage and maintain the health of the fish.

How often should the water in the quarantine tank be changed?

The water in the quarantine tank should be changed regularly, ideally 25% of the water every day. This helps maintain water quality and reduces the risk of contamination.

What role does salt play in the quarantine process?

Salt is added to the quarantine tank to help kill parasites, support the healing of any injuries on the fish, and boost their energy. It helps the fish adjust to the water conditions and recover from stress.

How much salt should be added to the water in the quarantine tank?

For every cubic meter of water, 1 kg of salt should be added. If the fish are weak or have visible injuries, you can increase the amount of salt to up to 3 kg per cubic meter.

What is the purpose of acclimatizing the fish fry to the pond water temperature?

Acclimatizing the fish fry to the pond water temperature helps prevent shock. Gradually adjusting the temperature ensures that the fish do not experience stress, which could lead to disease or death.

How long should the acclimatization process take?

The acclimatization process should take around 15-20 minutes. This time allows the fish to adjust to the pond’s water temperature gradually.

Why is it important to avoid placing dead fish back into the quarantine tank or main pond?

Dead fish can spread diseases or bacteria that may infect the rest of the fish. It’s crucial to remove and dispose of any dead fish immediately to maintain a healthy environment.

How can you prevent the growth of harmful bacteria in the quarantine tank?

To prevent bacterial growth, maintain clean water by replacing 20% of the water daily, and remove waste from the tank regularly. Additionally, antibiotics like enrofloxacin can be used to treat infections in the fish.

What should be done if the fish fry appear weak or have visible injuries?

If the fish fry are weak or have injuries, you should add salt to the water to help them recover and heal. Additionally, separate any fish that have serious wounds or visible fungal growth to prevent contamination.
