In our country, fishing can be done in many river basins, not only in natural river basins, but also in artificial fish ponds, that is, the way of fishing in black pits. It is very common to fish for crucian carp in black pits, because crucian carp is a common fish species. Many of the crucian carp in the black pit are directly put in, and within a short period of time after they are put in, the crucian carp has not yet adapted to the new environment, so it is not easy to open their mouths. After a period of time, when the crucian carp slowly adapts to the new environment, they are more easily attracted by the bait and more easily open their mouths. It is not certain how long the crucian carp in the

black pit will open its mouth. First of all, it has a lot to do with whether it is living water. In the running water, it is easier to open the mouth, and the crucian carp can open the mouth about 2 hours after it is put in; while in the stagnant water, the crucian carp will wait for a long time to open the mouth, and sometimes it takes about 2 days to open the mouth. In addition, at certain times of the day, crucian carp are more likely to open their mouths after being put in. For example, between 5 and 11 in the morning and between 4 and 6 in the afternoon, crucian carp is easier to adapt to these two periods, and the opening time will be shorter.

has been introduced above, the black pit just put the crucian carp, they need a period of time to adapt, and then can open. Some baits can promote the opening of crucian carp and attract them more easily. You can choose a bait with a slightly stronger taste, that is, a stronger impact. For example, bait with fishy smell, then we need to use small medicines with fishy smell, such as crazy red worm crucian carp and so on. In addition, the bait with wine flavor is also easy to attract crucian carp, and some grains can be used as raw materials, which are mixed with musk wine. Moreover, baits such as corn kernels can also be directly used as baits to promote the opening of crucian carp.
