Abstract:Fecundity of Triplophysa brevicauda from Qushui county in the Yarlung Zangbo River, China was estimated in this study. The gonadosomatic index of female T. brevicauda was significantly higher than that of male. Absolute fecundity of T. brevicauda was ranged from 1028 to 5508 eggs, and the mean value was 2804 eggs±1282 eggs. The relative fecundity of body length and body weight were (42±16) eggs per mm and (1006±292) eggs per gram, respectively. Significant positive relationship was observed between the absolute fecundity and three variables including body length, body weight, and gonad weight. A significant relationship between the relative fecundity of body length and body weight and gonad weight was found. However, no correlation between the relative fecundity of body weight and any of those parameters of fish size and weight was found. Distribution of egg diameter showed a single peak, which might indicate T. brevicauda did not spawn by batches.
