池塘养殖的蟹类由于早期蜕皮过频 ,性成熟一般较早 ,导致个体不大 ,经济效益受到影响 ,如今通过基因延长其早期蜕皮周期 ,控制蟹类生长成为可能。上海水产大学邱高峰博士率领的研究小组经过两年多的攻关 ,利用克隆技术在世界上率先定位并克隆了我国沿海主要经济蟹类——锯缘青 Because of the early molting in the ponds, the frequency of sexual molting in the ponds is earlier than that in the ponds, resulting in small individuals and economic impacts. Now it is possible to control the growth of the crabs by extending their early molting cycle through genes. After more than two years of research, the research team led by Dr. Qiu Gaofeng from Shanghai Fisheries University took the lead in positioning and cloning the world’s major economic crabs - Marigold
