There are different kinds of salmon, among them, most of them are live in the Pacific ocean and one live in the Atlantic oceanThe female salmon can lays hundreds of eggs, and for safe environment for the eggs, the female makes the nest or redd and they can make hollow with their tail in the gravel. These eggs remain in the gravel throughout the winter, and the embryos develop. In the spring, the eggs hatch and alevins emerge And help them to hide from predator and makes milt for fertilize.The pea size small eggs are hidden safely whole winter and immediately when the springtime coming they start to develop and the glassy eye starts to visible through a transparent egg.These are tiny fish with the yolk sac of the egg attached to their bellies. Alevins stay close to the redd for a few months. When they have consumed all of the yolk sacs and grown in size, these fish emerge from the gravel, and are then considered fry.Like placenta the food sacs attached to the stomach and they take their food energy from the stomach attached stomachSince during development taking more food and it finish quickly and the little fry start taking to other food among them plankton is the mostly takes.After development when it is growing for one year then they start to going to the sea, lot of danger is coming during headed to the sea, after long journey salmon reach to the mouth of the river close to the sea and they take plankton near the shore and turned into the silvery adult fish, then when it 4 to 5 years old they try for out of sea and reaching to the Arctic ocean and start taking shrimp and plankton and this time they are caught by the fishermanjourney to the upstream when their age is 6 years old they start to go back to the upstream from where they are hatch from the egg, and during all the way they start to get red bright colour, and after long tiring battle journey against strong current they reached their origin-destination and they start to lay the eggs and after laying eggs they began to die.
