Through 3 years estimation research, good germplasm of triangle sail mussel (Hyriopsis cummigii) was successfully obtained in China Five Largest Fresh Water Lakes. The Triangle sail mussel strain is charactered with quick growth speed, strong anti-disease, and significant growing characters.
Comparative study was conducted on the morphology, growth and molecular genetics of geographic populations of (Hyriopsis cumingii) in China’s Five Large Lakes and Zhuji cultured population. The application of tradition technology and combinative modern bio-technique to the research, researchers found out the Dongting Lake, the Poyang Lake and the Taihu Lake , these geographical population triangle sail mussel had a very obviously economic advantage in practice. After 3 years of estimation, these triangle sail mussel strains are very pure in gene, with obvious phenotype than native artificial farmed mussel in Zhejiang(a province in China). In growth speed, these stain is 15-25% quicker than native artificial farming mussel in Zhuji, 30%-50% more living rate, 20% more production rate.
