There is little oxygen and plankton in the water of Qinghai Lake. Why are there many fish in the water?

This problem should be explained from the perspective of geography and plate movement.

First of all, you should understand that Qinghai is located inland and is a plateau. Why did such a Tahu lake form? Long ago, Qinghai Lake was connected with the Mediterranean Sea in Europe. Later, due to the collision and compression between the Himalayan plate and the Indian Ocean plate, the Qinghai-Tibet Plateau rose, naturally separating Qinghai Lake from the Mediterranean Sea. However, animals, plants and aquatic organisms survived and multiplied, thus forming today's naked carp (commonly known as yellow croaker). By the way, there are fish in Qinghai Lake, but definitely not as much as the landlord said. Since the Qinghai Provincial People's Government 1994 issued the fishing ban, 20,000 fish have been released by workers, so they are still very endangered. This fish tastes fresh and tender.

Grandpa said that there were shrimps in Qinghai Lake decades ago, but on that special day in 60 years, they were "caught in the net" by hungry people, and now they are extinct. This has to be said to be a great loss for Qinghai people. Alas, it's annoying to think of a good one (Qinghai dialect)

1998 to 2000, it is said (note that I said "it is said", which does not represent my personal opinion! In the country we hate very much (the country under the banner of plaster), Zeng Jin proposed that they exploit Qinghai Lake resources for five years. They "helped" us to build the Qinghai-Tibet Railway, but their plot was shattered because of wise leadership! ! ! It is said that there are rare elements in the brain of yellow croaker (I don't know exactly). Anyway, I was very angry at the news, but I was excited that the people of China built the Qinghai-Tibet Railway themselves! !

Alas, welcome friends to Qinghai!
