Posted On : March 28, 2023

Introduction to bioflac fish farming:

Bioflac fish farming is a new and innovative form of aquaculture that combines traditional aquaculture methods with the use of biodegradable plastics. It is a low-cost, low-maintenance, and environmentally friendly way to grow fish. The use of biodegradable plastics allows for the fish to be grown in a closed-loop system, meaning that water used in the farming process can be recycled and reused. The biodegradable plastics are also designed to break down over time, meaning that the fish can be farmed in a sustainable manner. This type of farming has been found to reduce water and energy usage, as well as minimize the impact of pollutants on the environment. Bioflac fish farming has become increasingly popular in recent years and is now practiced in several countries around the world.

Working of Biofloc fish system:

The Bioflac Fish Farming System is a system of tanks and filters that uses beneficial bacteria to create a balanced environment for fish to live in. The main components of the system are the tanks, oxygenation system, filtration system, and bacteria. This bacteria is known as heterotrophic bacteria which consume ammonia and convert into protein. The tanks are filled with water and the fish are introduced. The oxygenation system helps to provide the fish with oxygen, and the filtration system helps to keep the water clean. The heterotrophic bacteria helps to break down the waste from the fish, converting it into usable nutrients for the fish. The system is designed to be able to operate with minimal maintenance, and is suitable for both commercial and home fish farming.

Set up for bioflac fish farming tank:

1. Select a suitable tank for fish farming. Choose one that is the right size for the type of fish you wish to raise, as well as one that has adequate filtration.

2. It requires proper aeration and balanced mixing mechanisms of oxygen supply and function the heterotrophic bacterial culture.

3. Install a biological filter, which will help to keep the water clean and free of toxins. This is especially important if you are farming more sensitive fish, such as tilapia.

4. Add enough gravel to the tank so that it covers the bottom completely. This will help to provide a substrate for beneficial bacteria to grow and proliferate.

5. Fill the tank with water and add any additional treatments or additives that may be necessary for the type of fish you wish to raise.

6. Test the water regularly to ensure that it is within the proper parameters for the type of fish you are raising.

7. Introduce the fish into the tank, and adjust the feeding schedule to meet their needs.

8. Monitor the fish regularly to ensure that they are healthy and thriving.

9. Clean the tank and gravel periodically to remove any waste or debris that may have accumulated.

10. Replace the water in the tank as necessary to keep it fresh and free of toxins.
