ABSTRACT:
This disclosure is concerned with applications of the discovery that the normal reversion of fresh-water-developed sea-type salmon smolt back to parr, usually within several weeks of smolting, can be prevented, and at the very least significantly retarded, by not removing the smolt to salt water, but by maintaining the same in dark volumes of fresh water with external contrastedly illuminated feed zones(s) to hold the fish in a continual smolt condition with continuing growth and without reversion to parr characteristics; and in some applications, effectively rapidly converting sea-type salmon to, or imbuing the same with, land-locked salmon characteristics.
