They mainly live in the northern Pacific Ocean and are distributed in the Sea of Japan in the northwest Pacific Ocean, the Sea of Japan in the north and the coastal waters of Mexico in the east.

Saury is also found in the Yellow Sea of China and the east coast of Shandong Peninsula.

Their favorite water temperatures range from 15 degrees to 18 degrees.

They are edible and are a common economic fish.

1. Is saury a marine fish? Is saury a kind of fish or an edible fish?

There are many standards for the classification of fish. For example, fish, if classified according to living environment, can be divided into two categories: marine fish and freshwater fish.

Their living environment is very different, they live in seawater and fresh water respectively, so their habits are relatively different.

In this respect, saury can be divided into marine fish, because saury lives in the ocean.

Specifically, the Pacific Ocean is the main distribution area of saury.

The favorite water temperature range of saury is between 15- 18 degrees, so it is more distributed in mid-latitude areas and less distributed in low and high latitudes.

In the northern Pacific Ocean, saury has the largest number.

For example, the Sea of Japan in the northwest Pacific, the Bering Sea in the north and some sea areas near Mexico in the east.

In China's waters, saury is also distributed, mainly in the Yellow Sea and the east coast of Shandong Peninsula.

Second, can saury live in fresh water? As mentioned earlier, saury belongs to marine fish, mainly distributed in the Pacific Ocean.

Therefore, saury has adapted to the environment in seawater.

There is a great difference between seawater and fresh water, especially salinity. The salinity in seawater is very high, while the salinity in fresh water is relatively low, which can be said to be a world of difference.

Saury adapted to the high salinity environment in seawater, and their physiological regulation mechanism also adapted to the seawater environment during the long evolution process. Therefore, if the saury is put into fresh water, it may not be able to adapt, or even die in a short time and cannot survive.
