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 often involves traditional techniques and local knowledge, allowing people to provide food for their families and maintain their livelihoods. Many communities around the world rely on subsistence fishing as a vital source of nutrition and income. It helps preserve cultural practices and fosters a connection to local ecosystems, ensuring that fishing is done sustainably and in harmony with the environment.
