"Pla kot khang" (Thai script: ปลากดคัง) (sometimes also called "pla khang" or just "pla kot" for short) is a type of catfish used in Thai cuisine for "tom yam" or, shortly blanched, to be eaten with a "nam chim". The school of fish in this image were photographed swimming in the Mae Chaem River beneath the bridge in the town of Mae Chaem near sunset. They were feeding off insects that were flying just above the water surface.
