湖南师范大学生命科学院成功研究出投入低、产出高、具有国际领先水平的“三倍体鲫(鲤)——湘云鲫、湘云鲤”。湖南师大生科院是从1988年开始三倍体鲤鱼和鲤鱼即湘云鲫、湘云鲤的研究的。这种鲫鱼、鲤鱼与传统的鲤(鲫)鱼相比较,具有如下显著特点:一是生长快。湘云鲫比普通鲫鱼生长快2～3倍,当年鱼苗可长到0.5公斤/尾;湘云鲤比普通鲤鱼快20-30％,当年鱼苗可长到0.75公斤/尾;二是不繁殖后代。由于湘云鲫、湘云鲤均是三倍体
Hunan Normal University, Academy of Life Sciences successfully developed a low input, high output, with the international advanced level of “triploid crucian carp (Cyprinus carpio), Xiangyun carp, Xiangyun carp.” Hunan Normal University, Institute of Biophysics from 1988 triploid carp and carp that is the cloud carp, Xiangyun carp research. This carp, carp and traditional carp (crucian carp) compared to fish, has the following salient features: First, fast growth. The growth rate of Carassius auratus is 2 ~ 3 times faster than that of ordinary carp, when the fry grows up to 0.5 kg / t, while that of Xian carp is 20-30% faster than that of common carp. In the same year, fry can grow to 0.75 kg / . Due to the cloud crucian carp, Xiangyun carp are triploid
