Do small fish run around in sultry weather?

Because when the weather is hot, the temperature is high and the air pressure is low, the solubility of oxygen becomes smaller. Fish will lack oxygen in water, so they should be close to the water surface to absorb oxygen. A more comprehensive answer is: the solubility of gas decreases with the increase of temperature and increases with the increase of pressure, so when the weather is sultry, the dissolved oxygen in the water decreases with the increase of temperature and pressure, so fish should breathe more oxygen near the water surface; So the answer is: the weather is sultry, the air pressure is low and the temperature is high, the solubility of oxygen in water is reduced, and fish should swim close to the surface to breathe more oxygen.
