It lies on the small river Roach, near the head of a long estuary.
For descriptions of other Cyprinids than the carp, see Goldfish, Barbel, Gudgeon, Rudd, Roach, Chub, Dace, Minnow, Tench, Bream, Bleak, Bitterling, Mahseer.
As soon as the ice breaks up in the delta innumerable shoals of roach (Leuciscus rutilus) and trout (Luciotrutta leucichthys) rush up the river.
It readily crosses with the white bream, and more rarely with the roach and bleak.
I started catching small dace and roach straightaway by fishing about 10 inches overdepth.
