  2. Eels

  3. There are two main types of eel – the shortfin and the longfin. There are fewer eels today because of the loss of wetlands and commercial fishing. when the eels are (15-30 years for shortfins, 25 years for longfins, and sometimes up to 80 years) they migrate to the Pacific Ocean to breed and die. Eels can be found throughout New Zealand. They live mainly in rivers and inland lakes but can be found in almost all types of waters, usually well inland from the coast.

  4. Whitebait

  5. Whitebait are caught with big nets that they use to block the entrances of rivers and streams New Zealand whitebait are the juvenile of certain galaxiids which mature and live as adults in rivers with native forest surrounds. The larvae of these galaxiids are swept down to the ocean where they hatch and then they move back up their home rivers as whitebait. The most common whitebait species in New Zealand is the common galaxias or inanga, which lays its eggs during spring tides in Autumn on the banks of a river amongst grasses that are flooded by the tide.
