1. Alevin (sac fry, yolk-sac fry)
In fisheries terminology, a larval salmonid that has hatched but has not fully absorbed its yolk sac, and generally has not yet emerged from the spawning gravel. Absorption of the yolk sac, the alevin's initial energy source, occurs as the larva develops its mouth, digestive tract and excretory organs and otherwise prepares to feed on natural prey.
