Growth period is long, and the Yellow River beach, which grows a large amount of ruderal, can be used as fish feed, these are all the superior of development fish production
Condition.And the main reason for domestic section of our province abounds with high-quality the Yellow River carp in history.The Yellow River carp is the same as the Songjiang River perch, Xinkaihu Lake
Fish, Song Hua River salmon are described as four big, China fish altogether.The Yellow River carp just has from ancient times " its ichthyophagy, must river carp ", " Lip river carp she
It is triangular bream, expensive such as cattle and sheep " say, to the top grade for food.The Yellow River carp is also delicious with its fine and tender taste, long excellent of the red tail of golden squama, figure shuttle
U.S. form, has won fame both at home and abroad, and is the valuable stock of fish in our province and China.The legend succeeded in the civil service examination in old times, it is almost widely known.It is white
The easily equal ancient times poet Zeng Weiqi in residence, which write the poem, to be assigned, and " dragonfish " is called.Folklore has " three ruler carp of the Yellow River, this in Meng Jinju,
Point volume not Cheng Long, comes back with all fishes " etc. fine verse.Since the Yellow River is very huge, the spawning ground of annual the Yellow River carp is not solid
It is fixed indefinite, so scientific research personnel need to spend a large amount of man power and material to go to the spawning ground for accurately finding the Yellow River carp.
