People sometimes have an non-sensical bias against hatchery fish though.
Whenever that bias comes to my mind, I think of the wild brown trout of
North America that I love to fish for and remember that each and every one
of those beauties, without exception, is descended from a hatchery fish.

I think the value hatchery programs is highly location-specific,
goal-specific. Being for *or* against hatchery fish in general is
pretty pointless. The introduction of exotic species raises a different
set of concerns (potential impact on native species, for example), than
the introduction of hatchery supplements to help restore declining wild
populations of the same species.
