Disappearing fishing boat at night

A few fishing boats, exclusively active at night, remain in a small fishing port. During the summer, these boats venture out to sea after dark. They use sulfur-generated gas for ignition to gather fish by startling them, causing the fish to jump. The fishermen then use the smallest nets to catch the fish. The captured small fish are used to feed larger economically valuable fish. Once the small boat is filled with the catch, it promptly returns to the port. This method emphasizes respect for the natural environment and limited capture, cherishing marine resources, and caring for the marine ecological environment to ensure the sustainability and beauty of the marine ecosystem.
