Air force weather

The first trick: change bottom fishing to floating fishing. When the water is short of oxygen, many fish, such as grass carp, catfish and silver carp, will float to the surface to provide oxygen. Carp and Wuchang fish, fish, red tip (Mongolian red) and Pelteobagrus fulvidraco will stay in a certain swimming layer and still have the urge to hunt. At this time, if the bottom of the fish is replaced by a float, the bait will hook to the swimming layer where the fish stays, otherwise the fish will be hooked. Although it is impossible to select the deep layer of floating fishing at once, it can be seen from several experiments that as long as there are fish bites, many fish stay in this swimming layer.

The second measure: dissolved oxygen in running water comes from the fluidity of water. The dissolved oxygen in the sea area of domestic water is always higher than that in the Jinghai area. Under the same hot weather conditions, fish in living water are better than those in still water. Therefore, when the weather is sultry and the fish don't bite in still water, we should look for places where the fish can unhook, such as the inlet and outlet of the water control project, the spillway of the reservoir, the drainage ditch of the river and the surrounding environment of its oxygen-increasing pump. Although this area can't catch up with fish on weekdays, it will eventually appear and get it, which is far stronger than sticking to clear water.

The third measure: it only takes a little wind to catch the water in the downdraft. The upwdraft is a breeze, so there will be wind in the downdraft. The upper and lower layers of water will cause thermal convection, and the flowing water will cause friction, so the dissolved oxygen in the water will definitely increase, and the dissolved oxygen will gather in the downdraft, and you will feel that the anoxic fish will gather in the downdraft. In addition, the wind gently blows the surge protector to increase zooplankton and suspended natural bait everywhere, and fish will be relatively good at finding food in the downwind theme activities with strong dissolved oxygen.

The fourth measure: Under the hot and anoxic temperature, many fish that are not anoxic will float to the surface for theme activities. Up-regulated fish are instinctive, and fish hidden in open water have no sense of security. They must find a natural environment with aquatic plants, so as to avoid the destruction of similar and powerful enemies and human civilization. In addition, fish have the growth habit of avoiding strong light, darkness and warmth. Therefore, relatively speaking, the smooth water surface with aquatic plants is much better, and the lateral relativity of hypoxia will be lighter. So, when hot and oxygen-deficient fish don't bite, why not try to drill holes in the cracks of coastal aquatic plants for fishing? The lighter the water in the fishing position, the better. Avoid fishing in the sea area around 1 m.
