The video shows a large group of fish swimming in the ocean. The water is clear and blue, and the fish are small and silver in color. They are swimming around a yellow buoy that is floating on the surface of the water. The buoy appears to be attached to a rope or line that is submerged in the water. The fish are swimming in different directions, some are near the buoy while others are further away. The sun is shining, and the light is reflecting off the water's surface, creating a shimmering effect.
