What is name of young fish name?

There isn't one specific name for a young fish, like there is for a young dog (puppy) or cat (kitten). The term "fry" is the most common and general term used for young fish.

However, depending on the species, there may be more specific terms:

* Larvae: This term applies to the very early stages of development when the fish is still in the egg or has just hatched.

* Alevins: This term is usually used for young salmon or trout, specifically after they have absorbed their yolk sac and are starting to swim and feed independently.

* Fingerlings: This term refers to young fish that are a few inches long, usually raised in hatcheries.

* Juvenile: This is a general term used for young fish of any species, once they have reached a certain size and stage of development.

So, when talking about a young fish, you can use "fry" as a general term or be more specific depending on the fish species and its stage of development.
