Breeding males are brilliantly colored; the back
of the fish and the lateral blotches become an intense, iridescent
blue-green, while the ventral portions of the body and head, the
spinous dorsal fin and the area between the blotches become brilliant
yellow and orange, the latter sometimes punctuated with reddish
dots. Important indicators of degraded water quality. They are
especially sensitive to sediment loading and probably to organic
loading from sewage effluents. Gilt darters are diurnal feeders,
feeding most heavily in the afternoon hours. Opportunistic feeding
according to the availability of accessable surface-dwelling insects.
Juveniles eat caddisfly larvae As caddisfly larvae decreased in
relative importance in the diet, midge and black fly larvae increased.
Mayfly naiads were most important in the diet of very young darters
and in the diet of pre-spawning adults. Length to 7 cm. |
