Recently, in the waters of the Three Gorges of the Yangtze River, some people recently photographed a group of big fish more than 2 meters long, some people say that they are Chinese sturgeons? After taking a closer look, they can't help but be startled, it turns out that this is a yellow diamond fish, also called catfish, they are not picky eaters, except for eating fish and shrimp, even the frogs and birds on the shore do not let go, as long as they can eat everything in their mouths!
Some people say that adult squid can reach 2-3 meters in length and weigh more than 100 kilograms, which is bigger than a child! The operation is as fierce as a tiger, so it is called the "tiger" in the water!
Seeing a group of catfish chasing a big turtle to attack, and chasing a large carp to besiege it, that scene can't help but remind people of Amazonian piranhas!
This guy eats a lot and has a lot of children!
It is said that someone ate catfish from the Yangtze River 50 years ago, and think that some of those big guys have passed their 60th birthday!
Fortunately, it is our local, and there are many outsiders who are also rampant, and it is said that some outsiders have been specially introduced before, and now it is estimated that they have been almost wiped out by our local overlords!
For example, this alligator gar weighs 45-72 kilograms, can grow to more than 100 kilograms at most, and is quite edible. Some people say that if it spreads in the waters of the Yangtze River, the catfish can be wiped out! Of course, most people say that they don't want to fish, and they will soon be on the table, and they will basically be eaten up in less than three years!
The Yangtze River, the cradle of Chinese civilization, is facing unprecedented ecological challenges. Recently, a group of giant fish with a length of more than 2 meters appeared in the waters of the Three Gorges area, which was mistaken for the precious Chinese sturgeon, but under closer inspection, it is the terrifying yellow diamond fish, commonly known as catfish. The proliferation of these creatures makes people sigh: the Yangtze River is crying.
Native to the Yangtze River basin on the mainland, the yellow diamond fish is known for its strong survivability and amazing fecundity. The non-picky eating habit makes the yellow diamond fish occupy an extremely strong position in the food chain. They not only hunt fish and shrimp, but also frogs and small birds on the shore, and eat almost everything. Eyewitnesses described a group of yellow diamond fish besieging a large turtle and a group of people chasing a large carp, all of which show their dominance in the Yangtze River ecosystem.
This situation has exposed a serious problem in the Yangtze ecosystem: an imbalance in biodiversity. The 10-year fishing ban was originally implemented to restore the ecological environment of the Yangtze River, but the reality seems to be unsatisfactory. The high reproduction rate and strong adaptability of yellow diamond fish have allowed them to expand rapidly in the absence of natural predators, creating new challenges for already fragile ecosystems.
There is also the introduction of alien species, which for some time was considered an effective means of increasing biodiversity, but now it appears that this practice can have unforeseen consequences. Some specially introduced alien species, which were originally expected to play a specific role in the ecosystem, are often unadapted or suppressed by native species, resulting in a sharp decline in numbers, or even a complete eradication. On the contrary, native species such as the yellow diamond fish have become the new hegemon due to their strong competitiveness for survival.
In the face of such a situation, we have to reflect on the need for more scientific and rigorous ecological protection and species introduction strategies. In the future ecological governance, more attention should be paid to the balance between species to avoid the squeezing of ecological niches caused by the overbreeding of a single species. At the same time, the introduction of alien species must be rigorously assessed and monitored to ensure that they do not pose a threat to native ecosystems.
The future of the Yangtze River requires us to watch together. When these "water tigers" flood the Yangtze River, we cannot sit idly by, let alone stop at amazement and worry. Effective measures must be taken to restore the original balance of the Yangtze River ecosystem, protect the rare and fragile native species, and let the Yangtze stop crying and regain its vitality.
As every resident living in the Yangtze River Basin, we should be aware of the urgency of ecological protection and actively participate in the protection of the Yangtze River. Only when each of us shoulders our responsibilities and works together can the Yangtze River get rid of the current predicament and regain its former vigor. Let us move forward hand in hand to draw a more vivid and harmonious picture for the future of the Yangtze River. [Heart]
