Examples
-
When a trout or salmon hatches from the egg called the alevin stage, it retains a significant portion of the yolk attached to the throat region.
-
In addition, individual life stages (e.g., egg, alevin, juvenile, adult) differ in their thermal preferenda linked to optimizing criteria specific to their developmental stage.
-
This yolk-sac allows the alevin to attain a relatively large size in the first month or so of its life and eliminates the total dependence on feeding.
-
The alevin stage is the stage in which the least mortality should be expected, and the little fish give but little trouble.
-
When they deplete their yolks, alevin emerge from the streambed as fry, and flit about in the pools for about a year, eating bugs and crawdads and tadpoles and smaller fish.
-
The eggs will hatch out alevin, the salmon's answer to tadpoles, larval fish with attached yolk sacs who live under the gravel for a few weeks.
Note
The word 'alevin' comes from a Latin word meaning "to lift up, raise".
