Maybe they wanted to get more fish for the buck. As Atlantic's are pretty tough,good jumpers and don't die after four years like most pacific species. I think they might be republicans. :lol:
from a reference source see below
Unlike the various Pacific salmon species which die after spawning semelparous, the Atlantic salmon is iteroparous, which means the fish may recondition themselves and return to the sea to repeat the migration and spawning pattern several times, although most spawn only once or twice.
