Winter is the coldest season of the year, and only hardy crucian carp can be caught. The cold hardiness of crucian carp lies in not hibernating, and if it does not hibernate, it needs to eat, otherwise its physical strength will not be able to keep up. And the larger the crucian carp, the more it can't stop, otherwise it will not be able to reproduce normally in spring, and the folk call this phenomenon "raising seeds". Therefore, if you can't catch crucian carp in winter, it's basically not because of the cold weather, but because you haven't found a fish nest. 
The fun or difficulty of winter fishing lies in finding the fish nest, no matter how expensive the nest material is, it can not attract the fish, because the activity and foraging range of crucian carp in winter is very small, and the premise of the nest is to find the fish nest, and the nest is near the fish nest, so that it is possible to gather the surrounding fish. If you find the right nest, the catch will certainly not be bad. How do I find a fish nest?In fact, the principle is very simple, in winter, the cold water temperature is low, the crucian carp has the habit of chasing temperature, and there may be fish nests when the water temperature is high. This is also the reason why crucian carp gather in winter, and there are always some areas where the water temperature is more suitable than other places, so it has become a common choice for crucian carp. 
Water temperature can vary depending on a number of factors, such as wind, light, currents, obstacles, and depth, but the most interesting is the effect of shade on water temperature changes. When the water table has frozen, the north wind anglers start to play ice fishing, and the fish that have just been caught are actually "steaming", which is enough to indicate that the water temperature in the deep water is high. But we all know that the water temperature decreases with the increase in water depth, for example, deep water is much cooler than shallow water in summer. Why is deep water warmer than shallow water in winter?This is because the density of water is highest at around 4 degrees, and when the air temperature drops, the water meter temperature starts to drop first, and the freezing also starts from the water meter, and the water at 4 degrees begins to sink, so deep water is warmer than shallow water. 
Fishing in deep or shallow water is actually a big problem, and sometimes the terrain is chosen properly, and the catch can vary greatly depending on the depth and distance. Specifically, it depends on the temperature conditions, the temperature is not low in the early winter stage, there is no need to fish deep water, at this time the shallow water is warmer than the deep water. Deep water is warmer than shallow water when the temperature is very low, so it is not accurate to say that winter fishing is deep. Taking the Yangtze River basin as an example, at least before the heavy snow season, there is no need to fish too far, and other seasons do not need 3The short game of 6 is an important part of the early winter stage. When the temperature is extremely low, you need to fish deep water, and if you want to reach the fish nest, a long rod on narrow water is the best choice. In addition to the depth of the water, another factor that has a greater impact on the water temperature is the orientation, which is naturally higher due to the unobstructed and longer sunlight hours. Therefore, it is recommended to fish the north and east shores in winter, as there is a higher possibility of fish nests, and the angler is more sunny and the fishing is warmer. Fishing to the sun is the constant truth of winter fishing. 
There are also obstacles, which are also key to affecting the water temperature. Some obstacles have a better heat absorption and thermal insulation effect, for example, there is a dead grass area underwater, commonly known as dark grass, the water depth is deep, the lighting is not affected, not only more heat preservation but also to prevent the fish inside from being washed by the current, and the possibility of naturally having a fish nest is higher. There are also reeds, the sunny side of the bridge piers, the boulders in the water, the back of the stones, etc., all of which are warmer than the open water. Wind can also affect the water temperature, and for winter fishing, it will also affect the casting and drifting, so it is best to find a sheltered location. Could it be that the water temperature in this location is much higher than in other places, so there must be a fish nest?That's not necessarily, if someone just caught it yesterday, the surrounding fish will be gone. The range of fish in the winter is relatively small, and it will take some time for new fish to replenish. So a good den, if you fish frequently, the catch will be less and less. 
Winter fishing is more recommended to use the method of multi-nest teasing fishing, which is also the advantage of this, the probability of encountering fish nests increases a lot. Please pay attention to the collection and like, update on time every day, thank you fishing friends!
