What is the difference between fry and fingerlings?

Fry and fingerlings are both terms used to describe young fish, but they refer to different stages of development.

Fry

- Recently hatched fish

- Have not yet developed fins

- Feed on yolk sac

Fingerlings

- Developed fins

- Actively feeding on external food souce

- Longer than fry (typically > 2.5 cm)

- Transitional between the larval and juvenile stages

As fish grow, they progress from fry to fingerlings and eventually to adults. The specific size at which a fish is considered a fingerling varies depending on the species, but it is generally when they reach a length of about 2.5 cm.
