Building an iAVS System
Integrated Aqua-Vegeculture Systems (iAVS) are a sustainable and efficient way to grow fish and vegetables in a closed-loop system. Building an iAVS system requires careful planning and attention to detail. Here are some steps to follow when building an iAVS system:
1. Site Selection: The first step in building an iAVS system is selecting a suitable site. The site should have access to a reliable source of water, be level, and have good drainage.
2. Design: Once the site has been selected, the next step is to design the iAVS system. The design should take into account factors such as climate, water source, species selection, system size, energy source, maintenance requirements, and cost.
3. Construction: After the design has been finalized, construction can begin. The first step is to excavate the site and create the fish tank and grow bed areas. The tank should be lined with a waterproof material such as EPDM rubber or PVC liner.
4. Plumbing: Once the tank and grow bed areas have been constructed, plumbing can be installed to circulate water between the two areas. A pump is used to move water from the fish tank to the grow beds where it is filtered by plants before returning to the fish tank.
5. Planting: After plumbing has been installed, plants can be added to the grow beds. Plants such as lettuce, herbs, and tomatoes are commonly grown in iAVS systems.
6. Fish Stocking: Once plants have been added to the grow beds, fish can be stocked in the tank area of the system. Fish such as tilapia or catfish are commonly raised in iAVS systems.
7. Monitoring: After construction is complete and plants and fish have been added to the system, it is important to monitor water quality parameters such as pH levels and ammonia levels on a regular basis. This will help ensure the health of both the fish and plants.
Building an iAVS system requires careful planning and attention to detail, but can be a rewarding way to grow fish and vegetables in a sustainable and efficient manner. By following these steps, growers can create a productive and sustainable iAVS system.
