Ello user !!!!!!!!!!!

Here is your answer,

===============================================

The change in temperature mainly happens in upper portion.

Lower portion remains cooler in summer hotter in winter.

Moreover the dissolved oxygen decreases with increase in temperature.

So in upper portion there is deficiency of oxygen also.

That's why aquatic animals prefer to stay in lower portion of water in summer.
