Excuse me, is it easy for fish to lack oxygen in rainy days?

It is necessary to make a concrete analysis of the rain. When it rains, there are many showers, and the weather is hot. Before the rain, the air pressure is very low, and the oxygen content in the water is reduced. The fish are uncomfortable due to lack of oxygen and have no intention to feed. When it rains, people feel sultry, and fish easily float their heads due to lack of oxygen. Because before the rain, especially before the thunderstorm, the air pressure is low, resulting in lack of oxygen in the water, so fish are easy to "float"-lack of oxygen. At this time, insects fly low and fidgety, and swallows have to fly low for food-swallows fly low in the snake aisle, and heavy rain is coming soon. In the same way.
