in ichthyology, a species of Cyprinus.
This fish is extremely common in our rivers, and gives the expert angler great diversion. The dace will bite at any fly; but he is more than ordinarily fond of the stone caddis, or May-fly, which is plentiful in the latter end of April and the whole month of May. Great quantities of these may be gathered among the reeds of sedges by the water-side, and on the hawthorn bushes near the waters. These are a large and handsome bait; but as they last only a small part of the year in season, recourse is to be had to the ant-fly. Of these the black ones found in large mole-hills or ant-hills are the best. These may be kept alive a long time in a bottle, with a little of the earth of the hill, and some roots of grass; and they are in season throughout the months of June, July, August, and September. The best season of all is when they swarm, which is in the end of July or beginning of August; and they may be kept many months in a vessel washed out with a solution of honey in water, even longer than with the earth and grass-roots in the vial; though that is the most convenient method with a small parcel taken for one day's fishing. In warm weather this fish very seldom refuses a fly at the top of the water; but at other times he must have the bait sunk to within three inches of the bottom. The winter fishing for dace requires a very different bait: this is a white maggot with a reddish head, which is the produce of the eggs of the beetle, and is turned up with the plough in great abundance. A parcel of these put in any vessel, with the earth they were taken in, will keep many months, and are an excellent bait. Small dace may be put into a glass jar with fresh water; and there preserved alive for a long time, if the water is properly changed. They have been observed to eat nothing but the animalcula of the water. They will grow very tame be degrees.
