Subsistence fishing is a practice where individuals or communities catch fish primarily for their own consumption rather than for sale or commercial purposes. This method is often used by people living in rural or coastal areas who rely on local water bodies for their food supply. It helps sustain their livelihoods and provides essential nutrients. The techniques used in subsistence fishing can vary widely, including netting, trapping, and line fishing. These methods are typically simple and environmentally sustainable, allowing communities to maintain their traditions while ensuring that fish populations remain healthy for future generations.
