The core point of winter fishing is to find the fish nest, as long as you find the fish nest, the catch is still very safe. This is because when the weather is cold and the ground is frozen, crucian carp have the habit of gathering in groups and spending the winter collectively in places with high water temperatures, so finding a fish nest is finding a group of crucian carp. The problem is that it is more difficult to find a fish nest, and the theory is really simple, just one sentence: **high water temperature** has a fish nest. Therefore, it is necessary to pay attention to the multiple factors that affect the water temperature, and secondly, to choose the right water surface, because the narrower the water surface, it will be easier to find fish nests. 
1. There are usually large crucian carp in fertilizer water, this is because the water quality and fertilizer are basically caused by algae, which is a manifestation of the abundance of algae, relatively speaking, the food will be relatively rich, and the wild crucian carp grows rapidly. If there is a certain length of water surface and a certain number of aquatic plants, it is definitely a good water quality for large crucian carp. Generally speaking, the water temperature is low in winter, the number of algae will be relatively small, if the water quality is the best in the winter, it must be caused by some reasons for the higher water temperature, and the effect of fertilizer water heat absorption and heat preservation is also better. The way to find a fish nest through fertile water is to find a place where the water quality is more turbid than the surrounding area, which is a representative of high water temperature. If it is generally a phenomenon of fertile water, you don't need to fish too deep in winter, and you can fish in open water. 
Second, clear water is actually the more normal water quality in winter, because of the small number of algae, the water quality is the best in the low temperature season, and the light transmittance is poor. The crucian carp in it is relatively less abundant than the fat water, and although it grows slowly, the fish species tend to be better. For winter fishing in clear water, it is best not to fish in open water, but to choose a location with obstacles, among which the vicinity of aquatic weeds and reeds is the first choice. Because clean water does not warm up as fertile water, the obstacle area will be warmer and more suitable for fish to hide. If it is fishing open water, it is generally a sunny and wind-sheltered location to fish slopes, underwater trenches and other terrain, and the water depth should reach more than three meters. 
3. Muddy waterMuddy water is special in winter, and finding a fish nest through muddy water is not fishing the water surface of the whole river is muddy water. But there is a special place, if two tributaries converge, one clear water and one muddy water, most of the fish are in the area where the muddy water and the clear water meet. If the water is too turbid, it will be close to the side of the clear water. Because muddy water is more suitable for hiding for fish, but clear water is not conducive to hiding. If a river with decent water quality has muddy water in some areas, there is a high chance that there will be fish nests. Because the fish in winter do not like to move, it is not completely immobile, as long as the fish are active, it is easy to cause the phenomenon of muddy water. This also has to do with the underwater environment, where fish are more likely to be found in silt bottoms, as they absorb more heat than gravel bottoms and the water is warmer. When fish move in places with a lot of silt, it is easy to cause muddy water. 
Fourth, bubbles bubbles are also an important skill to judge the position of the fish, and the effect is immediate, in the winter found that there are fish stars in the water, you can directly hang the bait to fish the place where the fish stars surface, because this is likely to be the location of the fish. Finding fish nests through the Fish Stars is more common when ice fishing, and the Fish Stars will be frozen in the ice and will be easier to spot. The fish don't like to move in winter after they get together, so when the ice is already very thick, it is easy to run into fish nests when the ice is frozen here. This also illustrates the characteristics of winter fish, respiration produces fish stars, and the range of fish is indeed small. It is not easy to find an oscyostar in winter, and you need to observe it carefully, but fortunately, the temperature is relatively low in winter, and the phenomenon of underwater fermentation is not serious, and there will be no phenomenon of taking the swamp bubble as an osthyo. 
Finally, to sum up: fertile water is suitable for winter fishing, fishing open water, aquatic weeds can be, but be sure to find a sunny and sheltered location. It is best to find dark grass and reeds for clean water and medium water, and if you want to fish for open water, you should also take shelter from the sun and wind, and the water depth should reach at least 3 meters. Small patches of muddy water in clear water, or areas with bubbles in the water, are direct evidence of a fish nest.
