Excellent response Salmo g. You did a good job explaining a complicated issue. A fish is not a fish. Amazing that some think so. Hatchery fish are a domesticated stock bred, medicated and often forced to grow at unnatural rates to suit fishery needs. Do you know of any other effort to rebuild a wild population (of something other than fish - horses, wolves, birds??) that relies on a long-domesticated counterpart? Just curious?
