Prompt 1: Determine the wind direction.
There is no smoke without fire, as is the case with wild fishing in black pits. Even if you fish in a black hole, there is a saying that if there is no wind and the temperature is right, it is not suitable for fishing.
There is a simple reason. The black pit is closed. Although the water is not particularly deep, the dissolved oxygen in deep water is definitely not as good as that in the upper and middle layers.
Tip 2: Look at the water color.
Experienced old birds know that black hole fishing is actually fishing for water quality, and the owner of the pond who can transfer water can really make the fish talk and shut up.
But for fishing friends, there is a simple way to look at the water quality. The water is inevitably dark and dirty. Even through the polarizer, the water is colorful, the water quality is too fat and the sludge is too thick.
Tip 3: Test the water temperature.
The demand for food for cultured fish in black pits is different from that in wild waters. Only when the water temperature is right, they will open their mouths to feed, which is why black pit fishing is good in the morning and evening and bad in the daytime.
Of course, we can't go fishing with a thermometer, but we can test the water temperature by measuring the temperature of the lead pendant, which is not difficult to operate.
Tip 4: Choose a fishing posture.
Through the above three skills, you can basically determine whether you can get off the pole, and choosing the fishing position has become the most important skill.
Choosing a fishing position is nothing more than choosing an edge and a corner. Whether the black pit is round or square, you should choose the downwind and the downwind angle. Even if the fish in the whole pond are in a bad mood, there is still great hope of catching fish.
