Young One of a Fish

There are different kinds of animals on Earth and the young ones of all these animals are called by different names. The young one of a fish is called a Fry or a Fingerling, depending on the developmental stage. Moreover, there are three main developmental stages of a fish which are mentioned below:

  • Egg Stage – This is the stage where the fertilized eggs develop into fish.
  • Larval Stage – This stage involves the larval fish that live off a yolk sac that is attached to their bodies.
  • Juvenile Stage – This is the stage when the fish spends time developing from fry to a mature adult.

Young fish have reached the stage of development where they can “feed themselves.” They become “juvenile fish” and are referred to or termed “fry or fingerlings” once they have grown “scales and working fins.” Typically, “fingerlings” are around the size of a finger. The “juvenile stage” of the fish lasts until it is “completely developed.” Young fish are mature adult fish that have developed from young larvae fish.
