The lowest temperature for catching grass carp is about 5 ℃. Although grass carp is a common fish with a wide distribution range, its cold resistance is not strong. Under normal circumstances, the water temperature of 10 ℃ will reduce their appetite and activity, but they can also ensure normal growth and development. When the water temperature is lower than 5 ℃, their appetite and activity will deteriorate, and it will become more difficult to fish at this time, so fishing is not recommended. However, you can also fish at about 5 ℃, so long as you prepare suitable bait for them and keep the correct fishing method, you can also catch grass carp.

The best season for grass carp fishing is from late spring to early autumn. At this stage, the temperature is comfortable, and the activity and appetite of grass carp are also the best, so the difficulty of fishing will be low. Especially when the water temperature is between 20-30 ℃, the activity of grass carp is the highest, and fishing is the most suitable at this time. In spring and summer, you can fish all day without time limit. In autumn, you can choose to fish at noon. Of course, it doesn't mean that grass carp can't be caught in winter, but the temperature in winter is low, which makes fishing more difficult. If you fish at noon on sunny days, you can also catch grass carp.
