Fish eggs, commonly known as roe, are the reproductive cells produced by female fish. They vary in size, color, and texture depending on the species. Fish eggs are often found in clusters and can be laid in freshwater or saltwater environments. They serve as a vital food source for many aquatic animals and are essential for the continuation of fish populations. In culinary contexts, caviar refers specifically to the salted eggs of certain fish, such as sturgeon. Fish eggs are rich in nutrients, including omega-3 fatty acids, and are enjoyed in various dishes around the world. They can be eaten raw, cooked, or used as a garnish.
