Salmon in the wild lay big
eggs stored with energy, and
the offspring have a high
survival rate after they hatch. Studies have shown that female chinook salmon raised in
captive breeding programs lay many more eggs than wild
chinook salmon. The eggs of
captive females, however, are
25 percent smaller. Smaller eggs
are less likely to survive in the wild and may eventually harm the survival of wild salmon populations into which captive females are reintroduced. Scientists are continuing to research the impact of human-controlled reproduction to ensure the survival of wild salmon populations.
