Rainbow Smelt

A slender silvery smelt that smells faintly of cucumber when fresh, schooling in the midwater of cool lakes and inshore coastal seas. Coastal stocks run far up rivers to spawn, some travelling hundreds of kilometres, and it favours clear water between about seven and sixteen degrees. It grows to around a third of a metre.
