"Um, actually, it does not cost much to raise chum salmon at a salmon hatchery... probably the least expensive species to produce from a typical fish culture facility."

least is kinda vague to me
how much exactly is U.S. dollars per fish returned would be my question followed with who exactly harvests how many of those fish and what exactly was the cost per harvested fish per person paying for those fish

uhmm
are they like $2 each? or $200
etc. etc.....
