The video shows a person measuring the length of a fish with a measuring tape. The fish is lying on a tray, and the person is holding the tape measure around the fish's body. The fish appears to be a large, dark-colored fish with a shiny, wet surface. The tape measure is white with black markings, and the person's hand is visible as they hold the tape measure. The background is not clearly visible, but it seems to be an indoor setting.
