The development of globalization has brought a lot of opportunities to many countries, and under the rapid exchange of communication, the economic development of each country has been rapid.
As early as the last century, experts in various countries were studying species from other countries and introducing them as the main economic species in the country.
No matter which country there is a large number of exotic species, such as the British hairy crabs, German crayfish, Chinese bullfrogs, tilapia and so on.
Most of the exotic species are thought to bring in good profits, but in the end they multiply and keep invading the local ecosystem, leading to ecological destruction and huge losses.
Some time ago, some anglers caught a strange fish with a strange appearance, especially in the head, from the overall point of view, it looks like a mutant fish.
This strange fish is actually called "duckbill" by most people, and the scientific name of this fish native to the Mississippi River in the United States is spoon-nosed sturgeon.
The reason why it is called a platypus is because the head is flat and long like a platypus, while the body parts are different from normal fish.
According to the understanding, the angler caught it in the lower reaches of the Yangtze River, when it was caught it did cause a lot of people to gather around.
In fact, the duckbill was introduced as early as 1988, when experts thought the giant freshwater fish had excellent genes and wanted to breed it into an economic species.
This fish has the same reputation as the Chinese sturgeon, Russian sturgeon, has a high value, the adult duckbill can grow to at least 2 meters, its weight can weigh up to 100 pounds.
It is also such an exotic economic species, its adaptability is strong, its reproductive capacity is the "best" in the fish, a child can produce 6 million.
And now there are a lot of breeding bases in China, the duckbill not only has food value, but also will be kept in the aquarium.
Only the stocking of duckbills and the escape of duckbill farms from rivers have led to the arrival of many duckbills in China's rivers.
Usually, invasive species are economically costly, wreaking havoc on local ecosystems and taking over the environment of native species.
But wouldn't invading China have other effects, given that the platypus can grow so large and outcompete native fish in every way?
It's true that duckbills have good genes, but in reality they are lifelong plankton feeders, and of course some crustaceans are also on their diet. That said, duckbills are slightly gentler than the larger, more aggressive carnivorous fish, so they don't have much of an impact to some extent.
Additionally, duckbills are picky about their living conditions, so if they can be found in the Yangtze River, it means that the water is of good quality and that a lot of fish will be able to survive. China's river management has been effective over the years, and the fish have been able to live freely in the water.
The duckbill itself was originally intended as an economic species, and is not found in the market, but only in some fine restaurants. According to the understanding, the duckbill fish meat is delicious, contains protein, amino acids, etc. in line with the human health diet, not only that it can make caviar, its price is 200-300 yuan per kilogram. As an ornamental fish, a duckbill less than 20 centimeters, its price is 40-50. Therefore, even if the duckbill fish came to all parts of China, and even flooded up, this time there is no need to be afraid of, one person a pair of chopsticks thing can be done, when the fish can grow up to one hundred kilograms, it is estimated that in China can be less than 10 kilograms.
In fact, invasive fish like duckbill are very common in these years, but we Chinese love fish.
Native carp, carp, grass carp and so on are basically used to eat, this time if you can change some other fish to eat, it is also a good choice. In this regard, you have seen duckbill fish in the wild? Welcome to discuss.
