Cultivating fishes in a side boundary refers to the process of raising and growing fishes in a confined area that is situated alongside or within the boundaries of a property or space where water conditions can be controlled to create an environment suitable for fishes growth. This method allows individuals to efficiently manage and monitor the cultivation process on a smaller scale, making it accessible for personal or small-scale commercial purposes. The size and design of the side boundary can vary depending on the available space and resources, but the main objective is to provide a controlled and suitable habitat for the fishes to thrive and reach their desired size for harvesting.
