Weather hot oxygen

Fish need to absorb oxygen dissolved in water. When the weather temperature is high, the solubility of oxygen decreases, and when the air pressure is low, the solubility of oxygen decreases, which leads to the decrease of dissolved oxygen in water, so fish will appear "floating head" phenomenon.

So, the answer is: when the weather is hot, the oxygen content in the water decreases.
