The better the weather, the more difficult it is to catch fish, and many anglers have this experience. This kind of good weather has two characteristics, one is that the temperature is high in the morning and evening, sometimes even as high as 15-20 degrees, and the other is that the sun is large and the water meter heats up quickly. Both kinds of weather will have a significant impact on the water temperature, and the fish is an ectothermic animal, it is difficult to quickly adapt to the change of water temperature, so it is natural to choose to close your mouth.
Studies have shown that when the temperature of the fish varies by about 10 degrees, the oxygen consumption of the fish is 23 multiples increase or decrease, and its body metabolism is changed with the change of water temperature, increase or decrease by 1 degree will change by about 10% (metabolism increased or decreased). In weather with large temperature differences, fish tend to swim to places with high dissolved oxygen content, and this kind of aerobic swimming is not controlled by our nest material and bait.
In winter, the sun is big, often blowing south wind, west wind, southwest wind, the water surface temperature rises sharply, the bottom temperature rises slowly, the water surface and the bottom of the water naturally form a temperature difference, the fish have the habit of swimming in winter, the water surface temperature rises, forcing the fish to float. At this time, you are still sticking to the bottom of the fishing, of course there is no mouth, do you have a mouth when fishing floats? Not necessarily, because the fish are affected by temperature changes and have a stress reaction, the body is unwell, the bait is also tasteless, and it is difficult to find the fish mouth when fishing floating.
The main reason for the good weather and the difficulty of fishing is that the water temperature rises due to the rising temperature, which affects the fish mouth. If we fish at a time when the water temperature is constant, we can also fish for a wild mouth.
One is to fish in the morning and evening, or even at night. In the fine weather with a large temperature difference, 6-9 o'clock in the morning, 3-5 o'clock in the afternoon, the water temperature is basically more stable, and the fish mouth is more normal, of course, the fish opening time in the morning is shorter, about seven o'clock before dawn, after the temperature rises at 9 o'clock, there is no mouth, two hours to nest to attract fish, the time is a little tight, but, 3-5 o'clock in the afternoon, it is relatively easy to grasp some, at this time, the sun is westerly, the water meter begins to cool down, the water surface bottom temperature difference is small, it is a good time to fish late. Conditionally, good body of anglers, can also choose night fishing, winter night fishing almost the whole low temperature period, small trash fish nest less, easy to encounter large carp.
The second is to fish for running water. The flow of water can reduce the temperature difference between the surface and the bottom of the water, and the water temperature in this water area is relatively stable, and the fish will open their mouths to feed normally. In winter, the probability of fishing with a boring rod and running water is very high.
The third is to fish for wind and waves. There is a downwind outlet of waves on the water surface, the temperature exchange between the bottom of the water surface is sufficient, the dissolved oxygen content is high, and the water temperature is relatively constant, which is the active place of the large carp. Of course, fishing downwind is mainly for light wind weather of level 1-2, if the wind level is larger, you can fish for deep water with smaller wind waves.
Fourth, fishing in shallow water. The reason is that in the weather with a large temperature difference, there is almost no temperature difference in shallow water, and the amount of dissolved oxygen in shallow water is relatively higher than that of deep water, especially in some shallow small waters, the deepest is only 15-2 meters, find a relative depth, it is easy to burst the rod.
