Fry plants make all kinds of sense. They are purely wild (or at least as "wild" and wild gets now days) and they can be provided at minimal cost and much higher hatching ratio than wild spawn. The trick I'm guessing is to see that they are transferred to receptive areas in proper densities.
It baffles me why this simple concept isn't massively supported.

Is it not as if the State wants to keep the fish runs suppressed? Perhaps to magnify "our" need for Federal monies?

Maybe we will receive a fish "brail" out!
