We will bring in alevins from the tanks that you are building in San Cristobal so that we can breed them here to.

As they are lighter than the alevins, the current will generally carry them to the lower end of the tray, whence they may be removed with a piece of gauze spread on a wire ring, or by raising and lowering the tray gently in the water in alternately slanting directions.

Sickly alevins will, as a rule, drop out of the pack, and lie on the bottom or against the end of the hatching tray, where they are carried by the current.

This sac is gradually absorbed but until it is absorbed the young fish are called "alevins."

The mortality which occurs in the actual hatching out of the alevins does not, however, by any means end the trouble which the fish culturist has to encounter in the rearing of char.

As soon as the yolk-sacs of the alevins are absorbed the little fish cease to be alevins, and are called "fry."

"Blue Swelling" of the yolk-sac is another disease from which alevins sometimes suffer, but I have never heard of any cure for this.

I have observed this affection in the alevins of the rainbow trout (_Salmo irideus_), the common trout (_S. fario_) and the Quinnat or Californian

Born in a ‘redd’, a shallow, gravel-covered depression dug by the female in the days before spawning, newly hatched salmon begin life as ‘alevins’, tiny, buoyant creatures with their yolk sacs still attached.
