草鱼Ctenopharyngodon idellus(Cuv.et Val.)是我国劳动人民发现的并久经饲养的一种淡水鱼类养殖对象。它有生长快,草食性等优点。但抗病力低,特别是在鱼种阶段死亡率高,一般在60%左右,严重的可达80%以上。为了解决这一生产上的问题,在文化大革命初期(1966年)我们和本所官桥试验场的工人同志一起,做了草鱼(♀)×团头鲂((?))(Megalobrama amblycephala Yih.)的杂交试验。1968年又进行了草鱼(♀)×团
Grass carp Ctenopharyngodon idellus (Cuv. Et Val.) Is a freshwater fish breeding object discovered by our working people and well-established. It has fast growth, herbivore and so on. However, the disease resistance is low, especially in the high mortality stage of fish species, generally about 60% and severe up to 80%. In order to solve this production problem, in the early days of the Cultural Revolution (1966), we, together with the workers’ comrades at the Guonag Bridge test site, made the grass carp (♀) × Megalobrama amblycephala Yih. ) Hybridization test. In 1968 another grass carp (♀) × group
