Dace, DARE, or DART (Leuciscus vulgaris), a fresh-water fish in the carp family Cyprinidæ (q.v.), and of the same genus as the roach, chub, minnow, &c. It chiefly inhabits the deep and clear water of quiet streams. It is found in Italy, France, Germany, &c., and in some of the rivers of England, but is very local. In form it is not unlike the roach, but rather more elongated; the mouth is rather larger, the scales smaller. The upper parts are dusky blue, becoming paler on the sides, and passing into white on the belly, the cheeks and gill-covers silvery white. It measures about 8 inches in length, and never exceeds a pound in weight. The dace is gregarious, and swims in shoals. It spawns in early summer. Its flesh is preferred to that of the roach, but is not highly esteemed. The dace is perhaps the liveliest and most active of the Cyprinidæ, and affords the angler fair sport both with fly and bait.
