Abstract:Growth characteristics of generation 2010 ( 4 to 15 months after hatching) and generation 2009 (16 to 27 months after hatching) A. fasciatus were studied in Xinchang of Zhejiang province, including the male and female growth difference, growth feature and the change in body shape. The results show that there are quite significant differences on the total length (Lt), body height (Hb), body width (D) and body weight (W) between male and female, the growth rate of female is faster both generation 2010 and generation 2009 in this species. The growth equation of generation 2010 and generation 2009 A. fasciatus are Lt=0.268+4.932Hb(r=0.9568), Lt=0.236+9.014D (r=0.9941), W=8×10-3Lt3.087 (r=0.9921) andLt=1.255+4.726Hb(r=0.961), Lt=1.364+8.281D (r=0.9534), W=7×10-3Lt3.179 (r=0.9623), respectively. The generation 2010 A. fasciatus has a fast growth rate from April to August, whereas generation 2009 A. fasciatus grows slow from June to August in breeding period. During the whole growth process, there is difference on the body shape between male and female. There are quite significant differences on the total Length/body height, total length/body width, body height/body width, total length/head length, head height/body height and caudal peduncle length/caudal peduncle height indexes of generation 2010 and generation 2009 A. fasciatus each month, while the total length/head height index has no significant difference in the same case.
