group of trout swimming in a shallow, man-made pool

group of trout swimming in a shallow, man-made pool. The pool appears to be concrete with a sandy bottom. The water is clear enough to see the fish swimming near the bottom of the pool. The fish are dark in color with spots along their sides. Water ripples are present in the water and reflecting the sky above. The edge of the pool is visible, along with some netting that is above the water. A voice, presumably from someone nearby, is heard briefly.
