| The "Road to Rebirth" of Indigenous Fish Species in Yunnan Plateau Lakes |
China News Service, Kunming, October 6th, title: The "Road to Rebirth" of indigenous fish species in Yunnan plateau lakes
China News Agency reporter Du Xiaoxiao
"In the past, there were a lot of anti-wave fish in Fuxian Lake.
I didn't want them to disappear, so I tried to make
them'swim back' to Fuxian Lake .
" Yin Shumao has been engaged in the protection of anti-wave fish source for 26 years because of his obsession
Anti-wave fish (Yanlang white fish), golden thread barb, big head carp and Dali bow fish in Dianchi Lake are collectively known as the "Four Famous Fish in Yunnan"
.
Anti-wave fish used to be a rare indigenous fish unique to the plateau lake Fuxian Lake.
There are 629 species of freshwater fishes in the southern part of the "Animal Kingdom", which account for about 40% of China's freshwater fishes, ranking first in China
.
Among them, there are 594 species of indigenous species, but there are 138 species of indigenous fish that are extinct, critically endangered, endangered and vulnerable
Yin Shumao's hometown, Goujie Town, Yiliang County, is only a mountain away from Fuxian Lake.
He was heartbroken when he saw this situation, and returned to his hometown in 1995 to protect the source of anti-wave fish
.
Initially, fish fry were collected from the fishermen of Fuxian Lake.
In the past 26 years, Yin Shumao has carried out a number of studies, and finally explored the anti-wave fish simulation wild breeding model, according to the fish’s living habits and genetic diversity for natural reproduction, to ensure the purity of the source of the fish, and the survival rate of the fish.
Up to about 90%, the incidence of abnormal fish is zero
.
Now, the anti-wave fish hatched by Yin Shumao has "swimmed back" to Fuxian Lake
.
"After observation and experiments, we found that the anti-wave fish can also play a role in purifying water quality and controlling the number of whitebait
Many people have the same desires as Yin Shumao
.
The Chinese government and scientific research institutions have made many efforts in the field of protecting Yunnan indigenous fish
It is understood that the Key Laboratory of Plateau Fish Breeding of Yunnan Province has established a high-level fish live resource bank and genetic resource bank, and carried out variety innovation based on this, and created a new species of soft-fin new light lip fish, golden thread barb and carp.
Distant hybrids
.
It has now reached the annual production capacity of more than 5 million indigenous fish seedlings, which can directly drive the annual output value of characteristic fish to more than 100 million yuan
"We are not only protecting the results show to the world, we have come through from the road to sustainable use of protection
.
" China Ke Xueyuan researcher Kunming Institute of Zoology, Laboratory Director of Yunnan plateau fish breeding YANG Jun-xing believes that the protection of indigenous fish Once it is integrated with the livelihoods of the people, they will protect them more actively, and sustainable use is the real protection
