Bi Fang stood on the exposed ice and looked around.
In fact, if you look carefully, the shocked audience will realize that this is indeed a river.
Its terrain is unique, with slight bulges on both sides, and the north bulge is higher, corresponding to the wind direction of the previous few days, but the middle is very flat, and it keeps winding away into the distance.
The existence of a normal river will scour the river bed, and the final result will be that the two banks are higher than the river surface, even after freezing.
A small number of aboveground rivers are actually not caused by nature, but are constructed by manpower. In order to ensure the stability of the rivers and avoid flooding or excessive diversion, natural rivers cannot be like this.
It can already be imagined that a river with riverbanks has condensed into a thick layer of ice due to the cold. Under the action of the snow, the river is completely covered. Under the action of the strong wind, the thickness of the snow on one side
Significantly higher.
Bi Fang poked open the snow on the ground and knocked it with a tree stick, making a dull sound. The ice layer was frozen quite thick, as he just said, at least ten centimeters.
"Since it is a river, it is already fresh water, but the structure of old ice and new ice is actually the same as that of sea water, so the judgment is correct and it has indeed been frozen for a long time."
"We have to be careful. Old ice is ice that has gone through at least one summer without melting. Its characteristic is that its surface is smoother than first-year ice."
Bi Fang opened up the nearby snow, revealing the center of a circle covering an area of about three or four square meters. He patiently observed the ice surface. He couldn't wait to start ice fishing.
Ice fishing is actually very easy as long as you find the right location. The fish will run to the hole on their own due to lack of oxygen. You don't even need to fish. You can stun them by just slapping the water surface hard.
“Generally, the fishing spots are generally located on the north bank facing the sun, where the water is slow, relatively deep, and there are large pits at the bottom of the river, more rocks, tree roots, and more aquatic plants. These places are easy to hide fish.
, gather fish.”
"If you are not familiar with the river, you can tell whether there are fish by looking at the color of the ice, the bubbles, and the cracks in the ice."
The reason why all the snow is pushed away is to distinguish this information more clearly under the sun, but it is already afternoon and the sun is about to set.
Bi Fang wanted to try to catch a few fish before dark to solve the problem of dinner.
"In terms of ice color, the depth of the water is blue, and the shallow water is more colorful. Where there are more aquatic plants, the color is greenish-brown, and some places are white."
"There are many bubbles in places. It is difficult to distinguish whether they are mud stars or underwater fish bubbles. Mud stars are more fixed in one place, densely packed, and about the same size, while fish stars are linear, of different sizes, and appear in one piece. They are easier to distinguish from the ice surface.
.”
"Ice cracks are the result of ice expansion. Places with ice cracks are often places where the ice is relatively thick and the water is relatively deep. After the ice cracks, there is relatively more dissolved oxygen in the water, and fish can easily gather. Generally speaking,
The sound of cracking ice will not scare away the fish, on the contrary, it will easily make the fish swim."
Bi Fang lay on the ground and carefully observed the old piece of ice in front of him, but he was slightly disappointed because it did not meet the conditions he said.
Helpless, he had to dig a few holes in other places, re-observe, and finally selected a more satisfactory location. The ice surface was slightly raised and the snow was much less than the previous locations. This was the upper reaches of the river.
"After digging a hole in the convex part, the river water will rise under pressure, and the overflowing water can flow away smoothly without accumulating into a pit."
"It's best to find ice surfaces with less or no snow. One of the characteristics of flowing wild rivers in winter is that the upstream river water often overflows from unfrozen areas, and the snow on the ice surface melts and then freezes into ice."
"Sometimes the snow is 40 to 50 centimeters thick on the shore, but there is no snow on the ice in many river sections. On the ice without snow, sunlight can enter the river bottom, which is beneficial to the photosynthesis of aquatic plants under the ice, and the temperature will be relatively higher.
It’s good for gathering fish.”
One novel key point was presented by Bi Fang one after another, which opened the eyes of many viewers.
I didn’t expect that ice fishing requires so much attention, and that you can analyze so many things just by looking at the ice surface, which is really awesome.
[No wonder I am always in the air force! I just lack the guidance of a master like Fang Shen]
【Damn it, fisherman!】
[I’ve given up studying, I’m going to give it a try this winter]
[If I had Fang Shen’s skills back then, Cuihua from the next village wouldn’t have left me]
Since there was no bait, Bi Fang placed more hope on the harpoon and continued to dig through the ice to enlarge the hole.
Then take off your gloves and scoop out all the crushed ice.
"Theoretically, the temperature of the ice-water mixture is zero degrees, which is higher than the surrounding temperature, but you will never feel warm when you put your hand in it. The rate of heat loss in the water is dozens of times that of the air."
“As long as you find the right location, ice fishing doesn’t require much other preparation.”
Bi Fang shook the water dry, wiped his hands with snow, put on his gloves again, and began to tap the water with a tree stick.
"When the ice bursts, the sound is very loud, which will make the semi-hibernating fish become active and swim to the entrance of the hole easily. At the same time, the sound of ice fishing will not scare the fish away. The fish often scatter and swim away, and then
Come together again."
"Keep your head, hands, and feet warm, especially your feet. Keep them dry. Water and moisture can easily make you sick. Don't sit for a long time, and move your body every hour. If you dig a hole, but there are no fish within an hour
Come here, then you can give up."
"If you are fishing, lift the fish lightly. When fishing in ice fishing, you should not lift the rod too hard after the fish eats the hook. To control the fish, lead the fish to the entrance of the hole and then lift it up. The bottom of the ice surface is not flat.
Instead, there are ice corrugations and icicles. If you lift the fish too hard, the fish will rush to the side of the hole, making it easy to get hooked."
Under Bi Fang's constant tapping, as expected, there was movement under the water.
Bi Fang stopped moving, changed the stick in his hand, pointed it downwards, slowly stirred the water to prevent the hole from freezing, and then quietly waited for the fish to swim to the hole.
After a few minutes, a few bubbles floated out from the hole mixed with crushed ice.
Bi Fang has sharp eyesight and quick hands, and the spear in his hand is as powerful as a rainbow. Although he has been in a state of malnutrition these past few days, his physical fitness is basically there. Even if it declines, he can still do it in a short burst.
Almost at the moment when the audience didn't see it clearly, Bi Fang started to lift up after thrusting out, a large splash of water was lifted up, and a big fish with spots landed on the ice.
It didn't seem to realize that it had been penetrated, and its body was swinging back and forth, throwing out a large number of water droplets, trying to escape back to the surface of the water.
Bi Fang kicked him away from the ice.
In the cold climate, it didn't take long for this big fish full of vitality to gradually freeze.
