Abstract

Motan, Thynnichthys polylepis is one of fish fauna in floodplain, Kampar Kiri River. The research was done from Juni until December 2005, was aiming to describe information on reproductive aspects of motan fishes i.e. sex ratio, gonado somatic index, gonado somatic stages, first size of maturity, fecundity, and egg diameters. Total samples were 479 individuals, consisted of 251 males and 228 females. The spawning seasons was on September-December. Fecundity ranged 718-27.636 eggs from 107 individual females. Spawning pattern was total spawner.
