Introduction: Why do the elderly in rural areas say "A hundred years ago, fish were inexhaustible"? Is there any scientific basis?
This year, due to a long drought and no rain, it has not rained heavily in my hometown for 3 months, so many rivers and streams have dried up.
The drought in the village was severe, and two of them were completely exhausted. During the National Day holiday, many people also went to dry ponds to catch fish. Many people were busy and sweating profusely, but they only caught a few loaches, , eels, and some river clams . As for other fish, there were very few.
This also made many elderly people in the village sigh: If were inseparable from the rural fish a hundred years ago, it would be inseparable from now on. There are very few fish in many rivers, ponds and reservoirs. Many common fish are rare now, and some big fish are even rarer.
So why do some people say "the fish from a hundred years ago are inseparable"? Is this a basis for saying it? Why are there fewer fish now?
The fish from a hundred years ago are inexhaustible, but they are also true!
In fact, for many elderly rural people, they should be very aware of the changes in rural areas over the years. Most of them know that compared to before, there are much fewer fish now. Not to mention a hundred years ago, even 30 years ago, there is a big difference compared to now.
I still remember that when I was very young, my parents went to the farmland to work. At that time, rice had to be planted for two seasons. Before each planting, some lime powder will be sprinkled in the rice fields to kill insects and sterilize the rice fields. When lime powder is sprinkled in the rice fields, not only insects will be killed, but also various loaches, eels and some small fish will be killed. But even so, every time you plow the farmland, you can always catch a lot of loaches, eels and small fish. Sometimes you can catch dozens of kilograms of fish in a piece of farmland.
is not only that, but there are many pools, pools, etc. in rural areas. They often have water after it rains or only after it rises in summer. And fish will appear over time. In winter, some people will dry the water in the pool and pool to catch fish. In this way, fish will be found in the pool in the second year.
Some farmers even dig fish ponds and never let fish go. They eat pure wild fish every year. If they are lucky, they can catch hundreds of kilograms of fish in a pond.
not only had many species of fish, but also many large fish. For example, grass carp grows to hundreds of kilograms, while grass carp weighs 70 to 80 kilograms and are often caught. is also because there are too many fish in rivers and reservoirs. Even if they are caught in large quantities every year, there are many fish every year, so it gives people the feeling that the fish at that time were "inexhaustible".
Why did the fish in rural areas in the past be "inexhaustible"?
In fact, this was also due to the reason at that time. The first thing in was that the environment was very good at that time and was very suitable for the growth of fish.
In the past, many places in rural areas had rivers, reservoirs and ponds. In today's words, the mountains and rivers were beautiful at that time, and such an environment was very suitable for the survival of various fish and could reproduce naturally. What's more, many fish have good reproductive abilities.
The second one is related to the backward fishing tools at that time. In the past, farmers' fishing tools were relatively simple. Most of them were simple tools made by farmers themselves, and some even used some farm tools to fish. In this way, when they are fishing, they often only catch a part of it, and may be a very small part. Most of the fish escape, which creates conditions for the subsequent reproduction.
The third one is related to people's concepts at that time.
I remember when I was a child, adults told us, "Going the mountain turtle , and going down the mountain pheasant can't touch it." It is because the turtle up the mountain is to lay eggs. If they are caught, there will be no turtle behind it. When catching fish, you should also remember one thing: as long as the big ones are, don’t catch the small ones.Only in this way can there be a continuous stream of fish.
Why are many fish in rural areas becoming rare now?
Nowadays, many people say that many fish are rare in rural areas, and some fish have even become "extinct". In fact, there is a reason.
First of all, the ecological environment in rural areas has undergone great changes . The water resources and environment in many places have been polluted, which is not conducive to the survival of fish.
In the past, there were basically no chemical plants or polluting enterprises. In recent years, the water in many rivers and lakes in rural areas has been polluted due to the discharge of sewage and waste. At the same time, farmers also use a large amount of fertilizers, pesticides, etc., which makes it difficult for many fish to survive.
is secondly because some people fish in uncontrollably. Compared with the past, has more advanced fishing methods and higher efficiency.
For example, the electric fish that many people hate has been rampant in the early years. Not only will the electric fish catch big fish, but small fish, fish eggs, etc. will be electrocuted. Even if they are not fished, they will be unable to reproduce, which shows how harmful it is.
In addition to this, some people use drugs to fish. Such uncontrollable and crazy fishing has led to many fish becoming rare.
There are also many places where rivers are built to dam, which directly leads to some small rivers being cut off. The green mountains and green waters of the past have now become stinky ditches.
written at the end
is also due to the above reasons, many fish in many places have become rare now. Now, the Yangtze River basin has been banned for ten years, and due to the increase in environmental protection measures, it has only been a few years since the fish resources in the waters of some places have been significantly enriched, which also shows that the harm of overfishing and environmental pollution is so great.
believes that as long as everyone cares about the environment and fishes scientifically and reasonably, it will not take long to return to the previous scene of "fish in the water, beautiful mountains and beautiful waters".
