Cage culture is a method of aquaculture where fish or other aquatic organisms are raised in enclosed netted structures, or cages, placed in natural water bodies like lakes, rivers, or oceans. This technique allows for controlled breeding and feeding, helping to increase fish production while minimizing the impact on wild populations. The cages can vary in size and design, depending on the species being cultivated, such as salmon or tilapia. Cage culture is popular because it can be more efficient and sustainable compared to traditional fishing methods, providing a steady supply of seafood for consumption.
