Recently, the Ministry of Agriculture and Rural Affairs issued Announcement No. 836, officially promoting 23 new aquatic varieties such as Yuxuan Huanghe Carp No. 2.
After successive generations of breeding, these new varieties have many advantages, such as fast growth rate, high survival rate and strong disease resistance.
The announcement is not only a recognition of these new varieties, but also a strong push for the future development of the aquaculture industry.
The 23 new aquatic products are: Yuxuan Yellow River Carp No. 2, grass carp "Husu No. 1", Siniperca chuatsi "Huakang No. 2", black Snapper "Suhai No. 1", Procellus Kwangyi "Xuyi No. 1", Macrobrachium roseni "Suhu No. 1", Penaeus vanae "Zhongxing No. 2", Penaeus vanae "Haijing No. 1", Penaeus vanae "Shenjiang No. 1", Chinese eriocheir "Yangcheng No. 1", Chinese eriocheir "Yangcheng No. 1" , Suhaihong No. 1 of the Mandarin clam, Fuhai No. 1 of the Crepe Pan, Yongle No. 2 of the Sinonovacula, Guihao No. 1 of the Hong Kong Oyster, Huanghuang No. 1 of the scallop, Anyuan No. 2 of the sea cucumber, Liaohaike No. 1 of the jellyfish, Dianyu No. 1 of the hybrid Cyprus, Yaolong No. 1 of the hybrid yellow Catfish, Baixiong No. 1 of the hybrid yellow Catfish, Shenghang No. 1 of the Flounder, and Yan of the Fujian Oyster The first 2 ".
Here are the highlights of several new varieties
Yuxuan Yellow River Cyprinus No. 2: Under the same breeding conditions, the growth rate of Yuxuan Yellow River Cyprinus No. 2 was 22.36% higher than that of Yuxuan Yellow River Cyprinus, with pure body color and neat specifications. The results of productivity comparison showed that the yield of Yuxuanhuanghe Cyprinus No. 2 was 15.19% higher than that of Yuxuanhuanghe Cyprinus. Yuxuan Huanghe Cyprinus No. 2 is suitable for cultivation in artificial and controllable freshwater bodies all over the country.
Grass carp "Husu No.1" : under the same breeding conditions, the weight of grass carp at 7 months and 19 months increased by 19.74% and 20.16%, respectively, compared with unbred grass carp. It is suitable for aquaculture in artificial and controllable fresh water bodies with water temperature of 18~32℃.
Siniperca chuatsi "Huakang No. 2" : On the basis of the new variety "Huakang No. 1" already bred, the easily domesticated strain "Huakang No. 2" was selected and bred. The success rate of feeding is as high as 90%, the feed coefficient is as low as 1.3, and it has the characteristics of short breeding cycle, fast growth rate and strong tolerance to low temperature. It is suitable for aquaculture in artificially controllable freshwater bodies with water temperature of 22~30℃.
Chinese eriocheir crab "Shenjiang No. 1" : Compared with other Chinese eriocheir crab species under the same breeding conditions, 90% of individuals completed reproductive molting 11 days earlier and harvested the same weight. It is suitable for aquaculture in artificially controllable freshwater bodies with water temperature of 15~30℃.
Hybrid Yalong No. 1: It can grow under the medium alkalinity water environment conditions below 50mM, with strong disease resistance and fast growth rate. Compared with parents, the weight increased by 19%~47%, and the growth advantage was obvious.
Hybrid pelteobagrus "Baixiong No. 1" : The breeding cycle is one month less than that of common hybrid seedlings, and the body size is larger. According to the density of 20,000-30,000 / mu stocking, the average mu yield can increase by 200-300 jin.

The popularization of these new varieties will have a profound impact on China's aquaculture industry. They will not only improve the efficiency and reduce the cost of farming, but also promote the green transformation of fisheries. In the future, with the wide application of these new varieties, China's aquaculture industry will usher in a broader development prospect.
