New Zealand Freshwater Fish

DSC_9352 Grass carp (Ctenopharyngodon idella) 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. Originally from Eastern China and Siberia, it is unlikely they will be able to breed here as they have very specialised breeding requirements, utilising extremely long rivers. To date a few controlled releases have occured around the North Island, mostly in the north *
