/əˈlɛvɪnz/
alevins are young fish that have just hatched from their eggs and still have a yolk sac attached to their bellies. They usually live in freshwater.
The word alevin is derived from the French word alevin, which means "small fish".
Alevins are often found in rivers and streams, where they seek shelter among rocks and vegetation to protect themselves from predators. They also feed on small insects and plankton.
