Sponge farming is the practice of cultivating natural sponges, primarily in marine environments. Farmers typically harvest sponges from the ocean floor, where they grow on rocks and coral. The most common types of sponges farmed include commercial sponges like Florida's wool sponge and Mediterranean sponges. To farm sponges, growers often use sustainable methods that allow the sponge population to regenerate. This involves carefully harvesting only mature sponges and leaving enough behind to ensure future growth. Sponge farming supports local economies and provides a renewable resource for various industries, including cosmetics and cleaning products.
