　　Yu Shan Crucian Carp is a high-backed, fast-growing, delicious, and silver-white variety of crucian carp developed through three generations of selective breeding from wild Ertix River silver crucian carp introduced in 1996 by the Panyu District Agricultural Science Institute from the Ertix River in Xinjiang. Although the original species is a sub-coldwater fish from the Arctic water system, practical experience has shown that it grows well in southern China, especially maintaining normal growth and weight gain even during the winter months in the region. When used as a co-cultured fish with Oreochromis niloticus, stocking 150–250 fish per mu results in fish weighing over 500 grams by the end of the year, growing 11.81% faster than Pengze Crucian Carp. As a co-cultured species, it can increase the yield of high-quality crucian carp by 75–100 kg per mu without affecting the production of the main cultured fish, ensuring stable economic returns. In March 2001, the Guangzhou Municipal Science and Technology Commission organized a panel of senior aquaculture experts to evaluate the project, who unanimously agreed that “breeding a new variety of crucian carp from Ertix River silver crucian carp and Feng carp is the first of its kind in China, and the technology is at an advanced domestic level.” This research achievement was awarded the Third Prize for Scientific and Technological Progress in Guangzhou for the year 2001, as well as the First Prize for Scientific and Technological Progress in Panyu District.
