The feeding regimes, including optimum feeding frequency, diel feeding rhythm, and optimum feeding rate, were established for gibel carp . The optimum feeding frequency for gibel carp was determined through 8week growth trial at five frequencies (2, 3, 4, 12 and 24 meals/d). Diel feeding rhythm of gibel carp was investigated by 24-hour trials at two body sizes (mean body weight: 20.5g and 76. 3g). The optimum feeding rate for gibel carp was estimated by the bioenergetics modelling and the validation trial was carried out based on the the feeding regimes of gibel carp.

异育银鲫的最佳投喂频率是通过设计5组不同的频率2、3、4、12及24次//天，经8周生长实验，然后比较鱼体生长和饲料转化效率获得的；异育银鲫的日摄食节律是通过对两组不同体重异育银鲫（平均体重20.5g和76.3g）24h内摄食率的测定而获得的；异育银鲫的最适摄食率是通过鱼类生物能量学模型的建立而获得的；最后通过生长实验对建立起来的异育银鲫投喂体系进行了验证。

The average contents of A, T, G and C were 14.1%, 16.1%, 30.2% and 39.6%, respectively, the contents of GC 69.8%） were obviously higher than those of AT. Using these primers, ITS-1 region can be amplified in other four Lutjanus species, but the lengths of ITS-1 were largely different between different species.
