We are about to eat without thorns Wuchang fish

The Yangtze River Daily Da Wuhan Client September 26 (Reporter Zhou Yan) On September 25, the Gao Zexia team of the Fisheries Institute of Huazhong Agricultural University revealed that since this year, they have used the first generation of miscellaneous composition (F0 generation) less stabbing fish. After the male and female mating breeding, the Wuchang fish (Tuan head) seedlings (F1 generation) that has no muscle thorns (F1 generation) will be further carried out next year. According to normal procedures, after the new type of quality is stable, the relevant certification of the country can be obtained, and it can be promoted on a large scale.

Professor Gao Zexia is in the test.

Last year, the Yangtze River Daily took the lead in reporting the Gao Zexia team of Huazhong Agricultural University to discover the main effect gene to regulate the growth of fishbone, and use gene editing technology to obtain the news of miscellaneous stabs. prick".

Yesterday, Professor Gao Zexia showed the latest achievements of his team on the breeding of Wuchang fish breeding in the "Exchange Meeting of Daquan Fisheries High -quality Development Forum and National Freshwater Fish — Featured Freshwater Fish Industry Technology System System System System System System System.

As can be seen from the displayed pictures, a 15 cm long and 51.1 grams of thorns -free Wuchang fish. Compared with the same length, there are almost no differences in the appearance, and in another X -ray film, you can see that you can see There are small thorns that grow horizontally in the body of Wuchang fish in the body that grows horizontally and shiny under the light, and shadow in the body without thorns Wuchang fish. The third skeletal dyeing picture clearly shows the comparison of the fishbone thorns. There are skeleton with martial arts with the skeleton and muscle spines. The lines appear dense, but the skeleton of Wuchang fish is sparse, without any extra small thorns. Gao Zexia said that the thorns -free Wuchang fish they breed this year are good, and more testing is currently underway.

The thorns -free fish is not only implemented on Wuchang fish. At the meeting, some other experts also reported the tests and applications on different fish after the introduction of the primary effect gene discovered by the Gao Zexia team. Following the main effect gene of the pilot of the grass carp and silver carp before, the latest gene knockout was also achieved on the catfish, and the F0 generation of thorns was obtained, and the muscle thorns decreased by 50%. Experts said that according to the current R & D speed, not only Wuchang fish, it is expected that we can eat a few major fish without thorns or less thorns soon.
