The video shows a person in a kayak holding a fish in their hands and measuring it with a ruler. The person is wearing a blue shirt and gloves, and the kayak is yellow. The fish appears to be a large one, and the person is carefully measuring it to ensure it meets the required size for a catch. The water is calm, and there are no other boats or people visible in the video. The person then releases the fish back into the water, and it swims away.
