The weather in Yin Shan for a month.

First, the concept of weather, water temperature and dissolved oxygen Fish is a low-temperature animal, and its body temperature cannot be adjusted. When the water temperature is high, the fish's body temperature will be high; when the water temperature is low, the fish's body temperature will be low; when the water temperature is lower than or higher than the fish's physiological threshold, it will enter physiological dormancy. In addition, once the water temperature rises or falls for a short time, the intensity exceeds 8~ 10 degrees, and the water temperature changes too much, so it is necessary to adapt to such temperature changes in a certain period of time. During the adaptation period, I will not eat with my mouth open. After talking about the water temperature, we should go on to talk about dissolved oxygen. Dissolved oxygen refers to O2 dissolved in water and oxygen in air, which is not a concept. Dissolved oxygen is the key to fish breathing in water. The higher the dissolved oxygen ratio, the more vigorous the fish's vitality, the lower the dissolved oxygen ratio, and the worse the fish's vitality, the less they want to eat. Theoretically, the shallower the water layer, the greater and heavier the proportion of dissolved oxygen in water, and the worse the proportion of dissolved oxygen in water. Finally, the weather, that is, different climates, such as cloudy, sunny, windy, rainy and snowy days. These different weather are mainly different air masses and air pressures in the atmosphere, which affect the light rays of the sun and form winds in different directions, cloudy days and sunny days.

Second, fishing spots and terrain fishing, how about fishing spots, which account for a relatively large proportion, good fishing spots, get twice the result with half the effort, bad fishing spots, get twice the result with half the effort. The so-called good fishing spots are simply areas where running water is blocked, areas where there is no sunshine for a long time, areas where dissolved oxygen is sufficient, and areas where floating garbage is easy to gather. For example, Wan Hui, Winding and Huajian are all areas where flowing water is blocked. Shade, bridge piles and Yinshan are all areas that are not exposed to the sun for a long time. Water inlet and outlet, the junction of deep water and shallow water, etc. They are all areas with sufficient dissolved oxygen, and these areas are widely distributed, and it is easy to collect floating garbage on the water surface. After fishing, the rest is the terrain. The so-called terrain is the environmental characteristics around the fishing point, such as the surrounding vegetation, trees, slope and so on. Because there are many good fishing spots, it is usually not suitable for fishing.

Third, there is a saying that there is no fish in the clear water pond, which is actually very reasonable, because it shows a basic reference of water quality, clarity, and there are many sundries in the suburban waters and water. All kinds of suspended solids, plankton, insects, impurities, microorganisms, garbage, the more the proportion of these impurities, the higher the deviation rate of the map after direct light, and the worse the definition. We call this water quality fat water. On the contrary, the introduction of impurities in water, after passing through a direct light source, has a relatively low refractive index and high definition. Everyone's water quality is fine water. The fatter the water, the more impurities and humus there are, which is more suitable for fish to survive and find food. If the water is thin and there are few impurities in the water, it is not suitable for fish to survive. Therefore, when we see clear water, most of us can be sure that it is not suitable for fishing here, but it is not that the fatter the water, the better. The water is too fat, even if it is shallow, zooplankton, microorganisms and humus in the water will consume a lot of dissolved oxygen in the water, and fish in the water will have no desire to eat because of long-term hypoxia.

Fourth, floating fish are underwater. When fishing, we can't judge the fish's eating hook in the water with naked eyes, so it reflects the floating effect. The act of floating in water is called floating. If you want to fully understand drift, let alone novices, there are drifts that you don't know clearly, but that doesn't mean novices don't have to master the basic knowledge of drift. It should be remembered that the key significance of floating phase is to judge the general situation of underwater according to the movement of floating phase. However, after all, once the bait is underwater, once the floating phase is stressed, it will swing from side to side and fluctuate up and down. No matter what kind of floating phase, it must be floating by external forces. Different sea areas, different weather, different kinds of fish in the water, and different floating phases when eating. Only by practicing personally and feeling more can we hold our tongue relatively accurately. For beginners, induction, summary and refinement are the most important. Don't blindly grasp the mouth, first learn to grasp the dead mouth, then learn to grasp the mouth, and then drift stages such as top drift, shift drift and small mouth.
