The chinook salmon are the largest of the Pacific salmon which makes them a very interesting fish to learn about. Apart from being a Pacific salmon residing mostly in the Pacific northwest region, this salmon species is also given the name spring salmon or spring chinook salmon. This is because they start to migrate towards freshwater during the spring as their spawning season begins in the summer. The life history of a chinook salmon spawn begins in fresh water bodies such as rivers until they return to the ocean or the sea. However, salmon populations are considered to be Threatened under the Endangered Species Act. Not just Pacific salmon species, but species all around the world have fallen prey to climate change. Climate change has resulted in depleting resources in oceans, rivers, streams, and other water bodies. This affects the populations of chinook salmon because chinook salmon are anadromous, meaning that they live in fresh water as well as oceans, seas, and other marine water bodies. Their populations must be saved to prevent them from going extinct.

Their range can be found in water bodies of the Pacific region, including the northwest and north Pacific. This includes places like California, the Chukchi Sea, Columbia River, and Monterey Bay. This species of fish can also be found in North American states like Alaska. This species can also be seen in the Asian range such as in the waters of Hokkaido in Japan. In Russia, chinook salmon can be found in Siberia's Anadyr River. Apart from these places that are native to the chinook salmon, this fish has also been introduced by humankind in places such as New Zealand and the Great Lakes.

What is a chinook salmon's habitat?

The habitat of the chinook salmon species is very interesting. This fish is born in bodies of freshwater like streams and rivers. Over the course of their life, they migrate to marine water bodies like the ocean from these streams. However, adult Chinook salmon again returns to fresh water during the spawning season as water bodies with freshwater serve as their spawning grounds. When it comes to a fresh water habitat, the ideal temperature for chinook salmon is 57 F (14 C). The stream type must also be swift-flowing and deep in nature. There are no such criteria for their ocean habitat or when they migrate.

How do they reproduce?

It takes two to seven years for chinook salmon to attain sexual maturity. However, adult chinook salmon return to its freshwater habitat to spawn at the age of three to four years. Male and female salmon form a pair for the purpose of spawning. Generally, the summer and autumn seasons mark the time for the spawning season in the life history of these salmon. The season may also vary as per the stream type where the fish spawn. Other factors include the type of rivers which influence when and where they will spawn. Fertilization of the eggs occurs externally, meaning that the female lays eggs in the water of the streams. For this, she digs up a hole which is known as a redd. The male then fertilizes the 3000 to 14,000 eggs laid in this redd.

After the process of fertilization, both parents guard the eggs to ensure that they are protected from possible harm. The entire process through which chinook salmon spawn is quite exhausting. This includes the act when the juvenile eggs are protected as well. As an aftermath of the colossal amount of energy lost during this spawn time, both adult parent salmons (males and females) lose their life before the eggs even hatch to life into juvenile salmon and move to the ocean or the sea.

What is their conservation status?

The conservation status of spring salmon is Not Evaluated according to the International Union for Conservation of Nature. However in the United States, there are 17 different categories of chinook salmon which are termed as ESU or Evolutionarily Significant Units. Out of these two categories, a couple of species are listed as Endangered by the Endangered Species Act. On the other hand, seven are listed as Threatened. Only one is listed as Candidate, while the remaining eight remain listed as Not Warranted. The Federal List of the States has listed this fish as an endangered species. In order to rectify this, strict rules and regulations are being imposed on the regulations over fisheries management.

During the courting period, a male swims in front of a female while emitting vibrations. Vibrations occur in accordance with the mass of the fish. Larger males are known to emit stronger vibrations.
