Abstract:Silver Carp(Hypophthalmichthys molitrix) is a traditional edible fish in China with the highest yield cultured.Yangtze River is served as an excellent resource for fish production and gene pool conservation of silver carp.This paper analyzed the age and growth characters from 151 silver carp samples collected from January 2008 and December at the National Original Breeding Farm(NOBF) located in Jianli County,Hubei Province(29°35′N,113°00′E) in which the four major Chinese Carps are cultured.The result indicated that the linear relation between body length(L) and scale length(R) was L=205.96R-6.374 0(n=151,r=0.948 6) and the function relationship between body length and body weight(W) was W=0.023 4L2.941 1(n=151,r=0.995 5).Moreover,the growth model could be described by Von Bertalanffy equation as Lt=93.77[1-e-0.208 7(t-0.031 1)] and Wt=19 293.35[1-e-0.208 7(t-0.031 1)]2.941 1.The growth inflexion was ti=5.14 years as the inflexion point of body length and body weight was Lr=61.47 cm and Wr=5 570.85 g,respectively.The value of growth parameters we got in this study,such as progressive body length,progressive body weight and age of inflecting point,have become smaller compared with the silver carp sampled in the Tian-e-zhou National Reserve in the middle of 1980s and Hukou area in 1990s.
