DSC_9436 Grass carp (Ctenopharyngodon idella) and Silver Carp (Hypophthalmichthys molitrix) were first introduced to NZ in the late 1960's for the purposes of aquatic weed control. Now aquaculturists are looking into their potential to be farmed as food fish for the table *
DSC_1158 Grass carp (Ctenopharyngodon idella) and Silver Carp (Hypophthalmichthys molitrix) were introduced to NZ in the late 1960's for the purposes of aquatic weed control. They seem highly effective when in large numbers and in closed waterways. These breeding ponds are located north of Auckland *
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 *
