<P> Juvenile fish go through various stages between birth and adulthood . They start as eggs which hatch into larvae . The larvae are not able to feed themselves , and carry a yolk - sac which provides their nutrition . Before the yolk - sac completely disappears , the tiny fish must become capable of feeding themselves . When they have developed to the point where they are capable of feeding themselves , the fish are called fry . When , in addition , they have developed scales and working fins , the transition to a juvenile fish is complete and it is called a fingerling . Fingerlings are typically about the size of fingers . The juvenile stage lasts until the fish is fully grown , sexually mature and interacting with other adult fish . </P>
