In the last two years, the market for the river crab industry has declined. The supply of megalopa in the north has exceeded the demand, causing many seedling enterprises to lose money. The breeding diseases of adult crabs in the south have continued to occur, especially this year, the "water shriveled" disease is very serious. This resulted in a large-scale reduction in the production of adult crabs. Some practitioners of the crab industry have lost confidence in this industry, thinking that the prospects of the crab industry are not good, and they have the intention to switch to other industries. In response to this problem, the frontier of aquatic products has analyzed the prospects of this industry and shared it with you here.

My country's river crabs are mainly distributed in three major water systems, namely the Yangtze River, the Liaohe River and the Oujiang water system. The Yangtze River system has the largest production of crabs, and Jiangsu Province is the main producing area of river crabs. With the gradual expansion of the scale of the crab aquaculture industry, a series of problems have emerged in the crab industry in Jiangsu: complex germplasm, degraded breeding strains; chaotic seedlings, brand seedlings have not yet been formed; disease prevention and control systems have not yet been perfected and other problems. Over the years, some river crab seedling and breeding units have used small-sized parents for artificial breeding, inbreeding and blind introduction of different water system branches, etc., resulting in the degradation of the crab germplasm and the smaller size. The industry is mixed.

The selection and breeding of fine varieties is the inevitable way for the development of the crab industry. By the end of 2015, there are 4 new species of river crabs that have been cultivated and approved by the National Aquatic Breeds Committee by relevant domestic units, namely "Yangtze River 1# and Changjiang 2#" selected by Jiangsu Freshwater Aquatic Products Research Institute and Panjin Photosynthetic Crab Industry. "Photosynthetic 1#" selected by Shanghai Ocean University Co., Ltd. and "Jianghai 21#" selected by Shanghai Ocean University, but compared with the huge industrial scale and the huge demand for seed, the number of improved species of river crabs is too small, and the contribution to the industry is also relatively high. Small.

In response to the above problems, some enterprises and scientific research institutions are also working tirelessly for the selection and breeding of crabs. According to incomplete statistics, at present, Jinkangda, Tongwei, Aohua, Tianbang, Haorun, Shanghai Sanzhi and other enterprises are all involved in the crab seed industry and even the industrial chain. Tianbang and Tongwei promote "Yangtze River 1#" and "Yangtze River 2#"; Aohua Group and Shanghai Ocean University jointly promote "Shenjiang 1#" and "Shenjiang 2#", which are early-maturing and late-maturing lines respectively. Some companies have not disclosed the source of seedlings, but are also doing work in this area, such as Jiangsu Haorun, Shanghai Sanzhi, and Jiangsu Jinkangda. Although the current crab seed industry is relatively scattered, in recent years, with the strengthening of scientific research strength and the capital investment of large enterprises, through acquisitions, mergers, cooperation and other forms, the seed industry will tend to develop on a large scale. The higher the degree, the higher the cost of credit. 2016 will be the first year of China's crab elimination. Whether it is seedling, breeding, feed, animal protection, circulation, and e-commerce, it will be a knockout competition. The brand seedling market will be formed in the next 2-3 years.

The leadership of our company headed by Li Dong is also far-sighted and has long realized the impact of germplasm resource optimization on the future river crab industry. Since 2005, foreign experts have been hired to carry out the selection and breeding of new species. After more than ten years of painstaking research, we have successfully cultivated a new species of river crab "Photosynthesis 1#", which is currently being promoted. This year, our company mainly sells macrophthalmia 1# photosynthetic larvae. Through the statistics of farmers' breeding situation, the result is that the advantages of photosynthetic 1# seedlings are very obvious. Xiamen Liyang Company has basically established a cooperative relationship with us, using their nationwide sales network to promote the "Photosynthesis 1#" crab seedlings. As long as our seedlings are of reliable quality, more companies will be required to join our crab industry. , Therefore, after the brand optimization, our crab industry will usher in a glorious era. At present, as long as we persevere, we will be able to wait for this day to come.
