I have discussed this before in a couple other topics. It has to do primarily with developmental or growth stages of the fish. There are a couple schools of thought or philosophies on this, depending on who you are talking to. Technically fry are the earliest stage and still contain egg yolk material. Very few people see the fish when they are at or in this stage of development. When the yolk is absorbed the fry swim out of the nest or away from the hatch site and become a free swimming larvae often referred to as post larvae or sometimes early or late larvae - post meaning post yolk fry or stage. When the larvae develops a complete set of fins and scales then it is usually referred to as a fingerling. Sometimes terms of early and late fingerling are used for small and large fingerlings. I will discuss this in more detail when I write the articles about small hatchling fish for PBoss Mag. Look for the first one about Bgill in 2008.
