Fish eggs are commonly called roe. An individual egg is an ovum (plural: ova), while spawn refers to eggs being released or deposited—or to that reproductive process.
Roe, ovum, and spawn: what each term means
- Roe: A mass of fish eggs in the ovary; in food contexts, the term commonly means edible fish eggs. FishBase defines roe as “the mass of eggs in the ovary,” while the USDA National Agricultural Thesaurus categorizes fish roe as food and lists “fish eggs as food” as a synonym. FishBase Glossary and USDA National Agricultural Thesaurus.
- Ovum (ova): The biological term for one female reproductive cell, or for more than one such cell. In everyday writing, “egg” is clearer.
- Spawn: Eggs released or deposited during reproduction, or the act of releasing or depositing them. Fisheries and Oceans Canada defines spawn as “to release or deposit eggs.” Fisheries and Oceans Canada Glossary.
How fish eggs are released
In most fish, spawning and fertilization happen externally: females release eggs and males release sperm, called milt, into the water, where fertilization occurs. This is typical, not universal, so “spawn” should not be treated as a description of how every fish reproduces. Virginia Tech Extension.

Is caviar the same as fish eggs?
No. Caviar is a particular prepared roe product, traditionally associated with sturgeon eggs. Fish eggs in general are not all called caviar. A University of Florida IFAS publication describes roe sold as whole masses or as individual eggs and discusses the traditional curing of sturgeon eggs as caviar. University of Florida IFAS.
