The video shows a person's arm reaching into a river, and then a fish swimming in the water. The person's arm is visible in the foreground, and the fish is swimming in the background. The water is clear, and the fish is moving slowly. The person's arm appears to be reaching out towards the fish, but it is not clear if they are trying to catch it or just observing it. The fish is medium-sized and appears to be healthy. The surrounding environment is not visible in the video, so it is unclear where the river is located.
