Whats a good ratio of trout to pound of molten aluminum?

Does it matter if they are brown or rainbow?

I find roughly about ten or twelve pounds of brookies to a half-ounce of
casting alloy -- just roughly. Usually, the metal is "lost" after too
many re-castings, and must be replenished.

That ratio can be increased significantly with the right surface finish
in the mold.

With the addition of sodium chloride, one can get the ratio up to a
couple-hundred pounds of blues per ounce of casting alloy.
