What is a young fish called?

A baby fish that has hatched from its egg is called a fry. Baby fish are almost transparent and look much alike despite the appearance and size of the parent fish. Their bulging stomach encloses the yolk, and tiny fins are starting to form.

If the fry is to have scales, they have not yet started to form. Dotted color pigment changes begin taking place on the skin. The yolk is absorbed in the stomach in about a week. A fry varies from between an eighth of an inch and a half inch, and this depends on species and egg size. Another name often used for a young fish that has matured somewhat and is no longer a baby is a fingerling.
