Can you catch crucian carp by night fishing in the first frost?

Yes, it is a good time to catch crucian carp after the first frost.

Crucian carp is a year-round foraging fish, and the temperature between 10-20 degrees is especially suitable for fishing, so the probability of catching big crucian carp is very high. The best time to produce large crucian carp in a year is late spring and early summer, and the other is late autumn and early winter.
