rriHP: Roach is generally distributed throughout England, Wales, and Scotland. In Ireland, 

 J- however, it is said not to occur, the Rudd {Lciulsciis erythrophthalmus), or Red-Eye, which 

 is exceedingly common in the north of Ireland, being mistaken for the true Roach. Accordnig 

 to Couch, the Roach is not known in Cornwall, and in Devonshire only in the lake called 

 Slapton-Ley. Its European geographical distribution is north of the Alps.
