Abstract
This paper is contributing the additional importance information on the reproductive biology of Rasbora tawarensis in relation to provide comprehensive our understanding on the reproductive biology of this species. Monthly sampling was conducted from April 2008 to July 2009. The highest absolute fecundity was observed in December, but it was not significantly different (p>0.05) from January, May, July, August, October and November. The highest relative fecundity was observed in July but it was not different significantly (p>0.05) from January, May, June, August, September, November and December. The average absolute fecundity was 3715.4±893.6 eggs, while the average relative fecundity was 518±95.64 eggs.g[sup]-1[/sup]body weight. The spawning frequency of the female was 2 to 11 days and fish was frequent spawned during the reproductive seasons in March, September and December.
