Cage culture is rapidly gaining attention from both researchers and commercial producers due to the rising global demand for fish, declining wild fish stocks, and the economic challenges faced by traditional farming. With a growing interest in sustainable food sources, aquaculture has emerged as a rapidly expanding industry, offering promising opportunities even for small-scale farmers. This method allows farmers to make efficient use of existing water resources, which may have limited applications for other agricultural activities.

The cages used in this project will be supported by pontoons, a universally recognized structure made from High-Density Polyethylene (HDPE), a durable material that ensures stability. These pontoons are square in shape, each weighing 7 kg, and are commonly used worldwide as floating docks in marine environments. The use of pontoons in this project provides a strong, reliable floating framework for the cages. With a lifespan of over 10 years, pontoons are a long-lasting and effective solution for sustainable fish farming operations.

The nets used in this project will be crafted from high-quality HDPE and nylon materials, ensuring durability and efficiency in fish farming. Three primary types of nets will be utilized: bird protection nets, fingerling nets, cage nursery and grow-out nets, and predator nets. Each net type features specific mesh sizes, designed to accommodate different fish growth stages. The estimated lifespan of these nets is approximately 7–8 years, making them a long-term investment for sustainable aquaculture operations.

In conducting cage culture, fisheries involved in this project are well-versed in the guidelines for responsible fish farming, particularly for species like Tilapia. We are committed to adhering to all relevant rules and regulations to ensure ethical and sustainable aquaculture practices.

Cage aquaculture involves cultivating fish within enclosed net cages in existing water bodies, allowing for a natural water flow while providing a controlled environment for growth. This system consists of a floating frame, net enclosures, and a secure mooring setup, including ropes, buoys, and anchors. The floating nets, available in both round and square designs, are capable of housing and growing a large number of fish. These cages can be installed in reservoirs, rivers, lakes, or other water bodies. Economically, cage culture is a cost-effective, low-impact farming method that offers high returns while maintaining minimal carbon emissions, contributing to a more sustainable and eco-friendly aquaculture industry.
