Quick Answer: A fry is a baby fish. In fisheries and aquaculture, “fry” usually means a young fish after hatching and around the stage when it begins feeding for itself. The exact boundary varies by species and context, but a fry is always a young fish—not a baby frog, bird, or mammal.
What Baby Animal Is Called a Fry?
The animal baby called a fry is a young fish. The term is widely used in fisheries, aquaculture, hatcheries, and aquarium keeping.
The Food and Agriculture Organization (FAO) defines fry as a young fish at the post-larval stage and notes that the term may be used broadly from hatching until the fingerling stage. In some contexts, “advanced fry” means a young fish that has absorbed its yolk and begun feeding externally.
| Term | Animal | Typical stage |
|---|---|---|
| Egg | Fish and many other animals | Before hatching |
| Embryo | Fish and many other animals | Developing inside the egg |
| Larva | Fish and many other animals | Early stage after hatching |
| Alevin / sac fry | Especially salmon and trout | Newly hatched, yolk sac still attached |
| Fry | Fish | Young fish after hatching; often beginning independent feeding |
| Fingerling | Fish | Older juvenile, larger than a fry |
| Juvenile | Many animals | Young animal not yet adult |
Why Are Baby Fish Called Fry?
“Fry” is a traditional fisheries term for very young fish. It does not refer to one species. Goldfish fry, guppy fry, salmon fry, trout fry, tilapia fry, and many other young fish can all be described with the same word.
The exact use of the term is not perfectly standardized. Some sources use “fry” broadly for fish from hatching until fingerling size, while others reserve it for fish that have moved beyond the earliest larval or yolk-sac stage. That is why the safest simple answer is:
A fry is a young baby fish after hatching.
Fry vs Larva: What Is the Difference?
The words overlap, but they are not always used in exactly the same way.
A fish larva is generally an early developmental stage after hatching, often before the fish looks or behaves like a small adult. A fry is usually a somewhat later young-fish stage, especially once active swimming and external feeding begin.
Because terminology varies by species and fisheries tradition, you may sometimes see very young fish called both larvae and fry.
Fry vs Alevin
An alevin is a newly hatched salmonid, such as a salmon or trout, that still carries a yolk sac. The yolk provides nutrition while the young fish remains in the gravel or sheltered habitat.
Once the yolk sac is absorbed and the fish begins feeding independently, it is commonly described as a fry.
Fry vs Fingerling
A fingerling is an older and larger juvenile fish. The name comes from the idea that the fish is roughly finger-sized, although actual size differs greatly among species.
A simple sequence is:
Egg → larva / alevin → fry → fingerling → juvenile → adult
Not every fish species or scientific source uses exactly the same stage names, but this sequence is useful for understanding the general progression.
Examples of Animals Whose Babies Are Called Fry
| Fish | Baby term | Notes |
|---|---|---|
| Goldfish | Fry | Common aquarium term after hatching |
| Guppy | Fry | Born live rather than hatching from an external egg |
| Salmon | Alevin, then fry | Fry stage follows yolk-sac absorption |
| Trout | Alevin, then fry | Similar salmonid terminology |
| Tilapia | Fry | Widely used in aquaculture |
| Carp | Fry | Common hatchery term |
| Betta | Fry | Common aquarium breeding term |
| Clownfish | Larvae, then juvenile | Marine aquarists often use larval terminology more precisely |
Are Guppy Babies Called Fry?
Yes. Guppies are livebearing fish, so the young are born as free-swimming babies rather than hatching from eggs outside the mother. Aquarium keepers still commonly call them guppy fry.
This shows that “fry” is a life-stage term, not a word limited to egg-hatching species.
Are Baby Goldfish Called Fry?
Yes. Baby goldfish are commonly called goldfish fry after hatching. They are extremely small at first and require suitable food, stable water quality, and protection from larger fish.

Is a Tadpole a Fry?
No. A tadpole is the larval stage of a frog or toad. Although tadpoles live in water and may look fish-like, they are amphibians, not fish.
A baby frog is therefore not called a fry.
Are Baby Sharks Called Fry?
Usually not. Young sharks are commonly called pups. Even though sharks are fish, common naming conventions differ among groups, so “fry” is much more common for young bony fish and in hatchery or aquarium contexts.
FAQ
What animal baby is called a fry?
A baby fish is called a fry.
What is a fry animal?
“Fry” is not a type of animal. It is a life-stage term used for a young fish.
What is a baby fish called?
A baby fish may be called a larva, fry, fingerling, or juvenile depending on its age, species, and developmental stage.
Why are baby fish called fry?
“Fry” is a traditional fisheries and aquaculture term for very young fish after hatching. The exact developmental boundary varies by species and context.
What is the difference between fry and fingerling?
A fry is younger and smaller. A fingerling is a later juvenile stage, usually after the fish has grown beyond the fry stage.
What is an alevin?
An alevin is a newly hatched salmon or trout that still has a yolk sac attached. After the yolk is absorbed and the fish begins feeding independently, it is commonly called a fry.
Are all baby fish called fry?
No. Different stages and fish groups use different terms. “Fry” is common, but larva, alevin, fingerling, juvenile, and pup are also used in specific contexts.
Final Answer
A fry is a baby fish. The term usually describes a very young fish after hatching and around the stage when it begins swimming and feeding independently. Salmon and trout may first be called alevins, older young fish may become fingerlings, and some fish groups use different baby names, but “fry” is one of the most common terms for young fish.
