11004-10112 Perch (Perca fluviatilis) were introduced to New Zealand in the late 1860s and early 1870s from Europe and are now widespread. Perch are easy to catch, making them popular with coarse fishermen. Since the 1970s, new populations have been established illegally in many lakes and ponds to create coarse fishing opportunities. However these voracious predators reduce the abundance of our native bullies, smelt and galaxiids in lakes and streams. They also reduce crayfish numbers and are assocated with the development of cyanobacterial blooms in lakes. Lake Waihola *

DSC_9428 Ornamental ponds may contain ornnamental fish such as goldfish or species introduced for ‘coarse fishing’ (defined by the quarry not being a ‘game’ or salmonid fish). Species such as carp, tench and perch are usually caught for the enjoyment of fishing rather than for the table. Hope, Nelson *
