Silver carp can be fished at a depth of 3-4 meters in winter. Silver carp usually likes to move in the middle and upper layers, but after entering winter, the temperature is relatively low, and the water temperature in the upper and middle layers will also be affected, so they will move into deep water or silt. Moreover, there are some areas with low temperature, and the water surface may freeze after winter, so they live in deeper areas.

However, these are only rough data, and how deep to fish depends on the weather and region. Generally, the winter temperature in the south is not particularly low, so it is OK to fish for about 3 meters. If it is sunny, it can be shallower. If it is winter, you should fish for about 4 meters when the weather is fine.

Silver carp likes sour bait, and some acidic bait can be made for them when fishing in winter. You can use bean curd residue, oil bran or wheat bran, yogurt, beer and honey. First, stir bean curd residue and oil bran evenly, then add honey and yogurt to mix, and finally add beer to stir slowly, so that the bait is in a slightly moist state. The prepared bait is put into a plastic bucket for sealed fermentation, and can be used after fermentation for about one month in winter. If the fermentation time is too long, it can be fermented with steamed corn flour plus white wine and medicinal liquor, which can be used in a few days.
