Salmon lay their eggs in many streams and rivers. Depending on the species, a female salmon will lay anywhere from 1,500 to 7,000 eggs in a nest or redd she has created by making a shallow depression in the stream bottom. The male fertilizes the eggs and then both fish push gravel over them to protect them.
Where are salmon eggs found?
Salmon lay eggs in a stream or lake. They lay their eggs in a nest made of small, rounded rocks called gravel. The nest is called a redd.
Where does salmon reproduce?
Spawning typically occurs in headwaters, though it may happen anywhere in a river if a suitable substrate of well oxygenated loose gravel is available. At spawning time (November to January), the female digs a depression in the gravel with her tail to deposit her eggs.
Does the salmon fish lays eggs in freshwater?
Salmon are born in freshwater. They migrate to the ocean before returning to freshwater in order to breed (also called spawning). Some kinds of salmon can travel as far as 1,000 miles (1,500km) upriver to lay their eggs in the same place they were born.
How long do salmon carry their eggs?

Do salmon return to where they were born?
Salmon come back to the stream where they were ‘born’ because they ‘know’ it is a good place to spawn; they won’t waste time looking for a stream with good habitat and other salmon. Scientists believe that salmon navigate by using the earth’s magnetic field like a compass.
Can salmon survive freshwater?
Salmon are anadromous fish, this means that they hatch in freshwater, live the majority of their lives in the saltwater ocean and migrate back to the freshwater to spawn. Salmon can survive in both freshwater and saltwater. There are behavioral adaptations as well as physical adaptations that make this possible.
Why can’t salmon fish reach back to ocean after laying eggs?
Pacific salmon use all their energy for returning to their home stream, for making eggs, and digging the nest. Most of them stop eating when they return to freshwater and have no energy left for a return trip to the ocean after spawning.
What time of year do salmon eggs hatch?

The cycle begins in freshwater, when a redd, or a female’s nest of eggs, is fertilized. These eggs remain in the gravel throughout the winter, and the embryos develop. In the spring, the eggs hatch and alevins emerge.
