Fishing

Dace are a popular sport fish species. They are known to put up a fight, and to be good for eating. They can be caught with a variety of methods, including float fishing, lure fishing, and legering. Fly fishing for dace using patterns that imitate small fry or invertebrates can be successful. Dace grow to around 50 cm (20 in) and 2.3 kg (5 lb) or more, but the most common size caught are around 30 cm (1 ft) and 450 g (1 lb) or less and anything over 40 cm (16 in) and 900 g (2 lb) is considered a prize catch.
