Description

The tench is a sturdy, dark-green cyprinid of the family Cyprinidae reaching about 70 cm. The stout body has very small scales, a thick layer of slime, strikingly small red eyes, rounded fins and a single short barbel at each corner of the mouth. The species likes warm, vegetation-rich, still or slow-flowing fresh water such as ponds, lakes and ditches, and tolerates low-oxygen conditions well. On the bottom it roots for midge larvae, snails, worms and plant matter. In the warm summer it spawns late; in winter it is barely active and partly buries itself in the mud. The tench is a popular and strong fish for angling.
