There were 63 female Pseudobagrus truncatus which ovaries at stage Ⅳ collected from the Yangtze River’s tributaries-MinJiang river in April-May 2013. The data for body length （L） , body weight （M） , net body weight （W） , ovary weight （Wa） were measured. The lapilli were used to determine the ages and egg diameters were measured with the aid of a vernier calipers. Counted with gravimetric method, the individual absolute fecundity （F） was obtained, and used for calculating the relative fecundity per centimeter （FL）, relative fecundity per gram （FW）, coefficient of maturing （GSI）, fullness （K）, and other indices. Based on these measurements and calculations, the relationships between the individual fecundity and the morphological indices of 63 female specimens of P. truncatus were studied. The results showed that the ages of the specimens ranged from 2 to 5 years old（Table 1）. The individual absolute fecundity （F）, ranged from 566 to 6 758 eggs （average 3 056 eggs ）. The individual relative fecundity per centimeter （FL）, ranged from 68 to 469 eggs （average 234 eggs） and the individual relative fecundity per gram （FW） , ranged from 45 to 349 eggs （average 145 eggs）(Fig. 3). The absolute fecundity and length relatively fecundity were power correlated with body length, body weight and coefficient of maturing, respectively. While weight relative fecundity was only power correlated with the coefficient of maturing, but not correlated with other morphological indices. Multi-regressive analyses showed that the individual absolute fecundity was significantly correlated with body weight and coefficient of maturing, the relative fecundity per centimeter was significantly correlated with body weight, net weight and coefficient of maturing, while the relative fecundity per gram was only correlated with coefficient of maturing. The multiple stepwise regression equation were as follow: F = 16 370.714 3 284.028 GSI 58.361 M，（n=63, R2 = 0.973, P < 0.01）; FL = 251.749 18.961 M 684.273 W 3 268.421 GSI，（n=63, R2 = 0.852, P < 0.01）；Fw = 138.590 837.641GSI，（n=63,R2 = 0.539, P < 0.01）. The distribution of egg diameter showed that P. truncatus was the fish with onetime spawner a year.
