(see figure above) The gene flow between hatchery-reared and wild populations is leading to a decline in fitness of wild populations. This data does not help us understand effects of gene flow on fitness. The gene flow between hatchery-reared and wild populations is neither helping nor hindering the fitness of the wild population.
