alevin
Newly hatched salmon
An alevin is a newly hatched salmon or trout still attached to its yolk sac.
During this stage, the tiny fish remains in the gravel of the streambed, absorbing nutrients from the sac before emerging to feed independently.
The term appears in fisheries biology and discussions of fish life cycles: The alevins will develop into fry within a few weeks.
