Smelt
There are two species of smelt in New Zealand. Common smelt are found throughout the country and Stokell's smelt are only found in Canterbury. The two species can be difficult to distinguish.

Smelt are small, shimmering, silver fish that form shoals in estuaries and rivers near the coast. They spend most of their lives at sea, returning to freshwater in spring and summer.

Some individuals return to freshwater as juveniles, but most return as adults when they are about 100 mm long. They can also be found in some lakes.

Some whitebaiters call smelt ‘silveries’ because of their distinctive colour or 'cucumber fish' because they smell like cucumber.
