<![CDATA[Stocking density is a key factor in the culture of bileh fish (Rasbora sp.) because it affects water quality, growth, feed conversion, and survival. This study aimed to evaluate the effect of different stocking densities on survival rate, feed conversion ratio (FCR), and growth of bileh fish reared in aquaria. The experiment was conducted for 40 days using a Completely Randomized Design (CRD) with four stocking density treatments (5, 10, 15, and 20 fish/m3) and three replicates. The results showed that stocking density significantly affected (P<0.05) absolute weight gain, absolute length gain, daily growth rate, feed efficiency, and FCR, with the best performance obtained at a stocking density of 5 fish/m3 (daily growth rate of 0.97%/day; feed efficiency of 24.95%; FCR of 4.16). Survival rate after 40 days of rearing was not significantly different (P>0.05) among treatments, with the highest value of 93.33% recorded at a stocking density of 5 fish/m3. Increasing stocking density increased competition for space and feed, thereby reducing growth performance and feed utilization efficiency.]]>
