Introduction: In the past, there were a few fish in the rural wells, and no one fed them, why can the fish survive tenaciously?
At present, rural areas are basically connected to running water, and some can reach 24-hour uninterrupted water delivery. This is a significant improvement in the daily life of the villagers. Water is the source of all things, and the production of any living thing is inseparable from water, which is also a history of living by water. In the area far from the river, the ancients took the well to get water, the well has also become an inseparable water source in the countryside, every morning or evening, there will be people to fetch water to eat, hot summer also like to soak watermelon in the cold well water, such watermelon is worthy of the current ice watermelon.
The wisdom of the ancients is infinite, and some wells in the village love to throw in a few fish, or a few turtles. Why? This is because in ancient times, public security was relatively chaotic, and wars were frequent, local forces could easily cause fights, and some in order to paralyze the combat effectiveness of the entire village, the method of choice was: poisoning the well, which was the source of water for the whole village to drink water, and if the well was poisoned. Villagers will naturally be poisoned because of eating poisonous water, light will be a serious illness, serious will lose their lives, so in order to prevent the well from being poisoned, a few fish or a few turtles in the well can play a monitoring role.
As long as the fish or turtles in the well live well, then the well water is naturally safe and non-toxic, and it can be safe to carry water to eat. If the fish has a vision and the fish turns over and dies, then the well water is polluted, and it is likely that it is poisoned by someone, so it is still very useful to put a few fish in the well. But the strange thing is that the fish in these wells have not been fed, these fish have no food source, but they are not starved to death, but they are tenacious, but they are not big, most of them are very thin, what is the reason?
Self-consumption is very small; the fish's own consumption is originally very small, which is also the characteristics of the temperature change animal, as a fish, can make its own adjustment according to the change of ambient temperature, so its own consumption is very low and very low, such a life habit can allow fish in the environment without food, can live normally for a long time, this is also the unique habit of the fish itself, the well water temperature is very low, the amount of fish activity is very small, the body's volatilization is also quite small, so that it can survive for a long time.
Sporadic drops; although the well is not fed food, but in the daily wind, grass, wind and rain, from time to time there will be some nutrient-rich things falling into the well. Like some leaves, fruits, grain and other items will fall into it from time to time, although these items are not much, but they can also be swallowed by fish as food, playing a certain role in supplementing nutrition, so they can also tenaciously maintain life.
Well microbial reproduction; well wall, well bottom and other places, over time, will derive a lot of microorganisms, moss, etc., there will be some other insects and eggs in the water, although the number is far less abundant than other waters, but for the small number of fish in the well, it can still maintain life.
With the smooth flow of rural tap water, the number of rural wells is also getting smaller and smaller, many rural wells have been backfilled, becoming flat land, wells with a long history in the countryside, and finally completed the mission, replaced by tap water, do you still have wells in your rural hometown?
