After mating, females lay eggs in gravel nests called redds, where males fertilize them externally. This reproductive strategy is common among most salmon species.

External, like most fish.
They reproduce externally. The male 'courts' the female, she scoops a shallow 'nest' from the river-bed with her tail, and lays hundreds of eggs. The male then swims to the same area and releases a cloud of sperm. The eggs are left to develop on their own - with no further help from the adult fish.
Female goldfish have ovaries to produce eggs, and reproduce externally. Male goldfish have internal testes, and they also reproduce externally.
